another is apparently in the natural shape in which it was found.

It is worth recapitulating here, that native gold, silver, copper, and iron, were all found on the altar of the large mound in this group, and that all were manufactured into ornaments simply by hammering.

On the altar of another mound of the group were several terra-cotta figurines of a character heretofore unknown from the mounds. Unfortunately, these objects, as well as others found on the altars, had been more or less burnt; and many of them appear to have been purposely broken before they were placed on the altars. Many pieces of these images have been united; and enough has already been made out to show their importance in the study of early American art. The peculiar head-dresses, method of wearing the hair, and the large button-like car-ornaments, shown on these human figures, are of particular interest. The shape of the ear ornaments leaves no doubt of the character of the spool-shaped objects previously referred to. On the same altar were two remarkable dishes in the form of animals, carved from stone, which have been nearly restored from a large number of small fragments. With these were a serpent cut out of mica, several hundred small quartz pebbles from the river, and nearly three hundred astragali of Ideer and elk. As but two of these bones could be obtained from a single animal, and as there were but one or two fragments of other bones, there must have been some special and important reason for collecting so large a number of these particular bones. A finely made bracelet of copper, and several other ornaments of copper, a few pearls and shells and other ornaments, were on this altar, with two large masses of native copper, and a mass of unworked meteoric iron. Many fossil shells were found on both altars.

Harvard college observatory, Cambridge, Mass. Astronomical photographs. —It is proposed to form, at the observatory, a collection of photographs of the heavenly bodies and of their spectra. Original negatives would be particularly valuable. It may happen that some such negatives, having slight imperfections which would limit their value for purposes of engraving, could be spared for a collection, and would be as important, considered as astronomical observations, as others photographically more perfect. In some cases, astronomers may be willing to deposit negatives taken for a special purpose, and no longer required for study, in a collection where they would retain a permanent value as parts of an historical series. Where photography is regularly employed in a continuous series of observations, it is obvious that specimen negatives only can be spared for a collection; but in such cases it is hoped that some duplicates may be available, and that occasional negatives may hereafter be taken for the purpose of being added to the collection, to exhibit recent improvements or striking phenomena. When negatives cannot be furnished, glass positives, taken, if possible, by direct printing, would be very useful. If these, also, are not procurable, photographic prints or engravings would be desirable.

The observatory already possesses many of the early and historically important specimens which would naturally form part of such a series. Among these may be mentioned four series of daguerrotypes and photographs of various celestial objects, taken at this observatory. These series were respectively undertaken in 1850, 1857, 1869, and 1882.

Copies of memoirs or communications relating to the specimens sent, or to the general subject of astronomical photography, would form an interesting

supplement to the collection. A part of the contemplated scheme will involve the preparation of a complete bibliography of the subject, including a list of unpublished photographs not hitherto mentioned in works to which reference may be made.

The expense which may be incurred by contributors to the collection in the preparation and transmission of specimens will be gladly repaid by the observatory, when desired.

- Special reports Nos. 56 and 57 of the U. S. department of agriculture for February and March, 1883, are entirely occupied with statistics. No. 56 opens with a report upon the numbers and values of farm-animals in the several states and territories, including a comparison with the corresponding statistics of last year. These show that there has been a decided increase in the number, and in the average price per head, of these animals. The statistics of the cotton-crop point to a probable total movement of not less than 7,000,000 bales, of unusually good quality; making the total crop nearly four per cent larger than the great crop of 1880. The report contains, also, a comparison of the prices of English and American agricultural implements, an article on

transportation-rates in Europe, and a list of transportation-rates on the more important rail and water routes from the west to the seaboard. All these are obviously of more or less general interest; but it is difficult to see how it can be considered the duty of the department to publish, as it does in this report, a gratuitous advertisement of one particular western railroad, avowedly furnished by its western passenger-agent. Report No. 57 is on the distribution of the corn and wheat crops of 1882, and the comparative quantity still remaining on the farm. Statistics are also presented regarding the extent and character of the domestic uses of these crops, and tables of transportation-rates are appended to the report.

- The U. S. geological survey has commenced the publication of octavo bulletins to receive such papers, relating to the general purpose of its work, as would not properly come under the heads of annual reports or monographs. Each paper will be issued separately with a distinct number, and will have two paginations, one proper to itself, at the top; and one belonging to the volume, at the bottom, -a most convenient arrangement. The first number, just issued, contains a paper by Whitman Cross on hypersthene-andesite, and on triclinic pyroxene in augitic rocks, with a geological sketch, by S. F. Emmons, of Buffalo Peaks, Col., where the principal rocks examined were found. Mr. Cross urges the need of a re-classification of the andesite rocks, and concludes that the chief subdivision of the augite-andesites may much more properly be called hypersthene-andesite Two plates accompany the bulletin.

- At its two hundred and thirty-third meeting, held April 7, the Philosophical society of Washington listened to Prof. W. C. Kerr, on the Geology of Cape Hatteras and the adjoining coasts; to Mr. H. F. Walling, on Topographical indications of a fault near Harper's Ferry; and to Mr. S. F. Emmons, on Ore deposition by replacement.

- At the annual meeting of the Cincinnati society of natural history, April 3, the following officers were elected: president, Dr. J. H. Hunt; vice-presidents, Professors John Mickleborough and George W. Harper; secretary, Davis L. James; treasurer, S. E. Wright; librarian, A. E. Heighway, jun. The report of the treasurer showed a balance in the treasury. The membership dues paid during the year amounted to a larger sum than in any previous year. Reports of the curators and custodian were handed in. The latter stated that the use of the museum by instructors of the high schools and academies was increasing yearly. The collections had been increased largely by donation and purchase, and were as well displayed as the limited space permitted.

FRIDAY, MAY 4, 1883.

THE PROPOSED MEETING OF THE BRITISH ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE IN CANADA.

THE British association has not yet ventured to hold its meetings in any part of the empire beyond the limits of the British Islands. It has, however, so far crossed the sea as several times to hold meetings in Ireland; and its sister-association of France has set it an example by holding a meeting in Algeria. The idea. of such extension of its geographical range is not altogether new. Projects of an international meeting have at various times been discussed, both in Britain and the United States; and it is understood that the present governorgeneral of Canada, who has shown much interest in the scientific progress of the new dominion, has had correspondence with leading men of science in England, with the view of either bringing the association to Canada, or securing a representative delegation to meet with the recently established Royal society of Canada.

The project of a visit to Canada only assumed definite form at the meeting last summer in Southampton. A motion was proposed, we believe by Capt. Bedford Pym, in the general committee, that the association should meet in Canada in 1883. This was lost on a division; but it was understood by the promoters of the scheme that the unfavorable result was in part due to the fact that they were unable to produce a definite invitation from any Canadian city. After the decision to meet in Southport in 1883, they therefore felt at liberty to propose that the meeting of 1884 should be held in the city of Montreal; and this was carried. Unfortunately, however, there was no official communication of this resolution till after the close of the meeting of the American association in Montreal: otherwise some steps might have been taken toward a combined gathering in 1884.

As soon as the resolution of the association was definitely known in Montreal, a movement was made to respond in a fitting manner. After a preliminary meeting called by the

No. 13. 1883.

president of the board of trade, and at which there were representatives of the McGill university and of the Natural history society of Montreal, the mayor was requested to call a public meeting, which was large, influential, and enthusiastic, and which passed resolutions pledging the city to do all in its power to make the meeting successful; appointing, at the same time, a large committee of leading citizens to carry these resolutions into effect.

In so far as accommodations for the meeting is concerned, and funds for its expenses, there can be no doubt that Montreal can entertain the association as well as any of the British cities in which it ordinarily meets; and its geographical position and facilities for access, and for communication with all parts of Canada, the northern states, and the west, present many attractions; while there is reason to hope that a meeting of the British association in Montreal would be attended not only by all interested in science in Canada, but by large numbers of the scientific workers of the United States. The experience acquired last year in entertaining the American association will also afford very valuable guidance. It was felt, however, that the real difficulty lay in the transportation across the ocean of so large a body as the British association, or even of that scientific nucleus of it which constitutes its essential part. The matter was therefore brought under the notice of the dominion government with the view of securing aid toward the passage across the Atlantic; and it is understood that a grant will be made sufficiently large to insure free passages to the officers of the society, and some of its more important members, who will also be the guests of the city, and reduced rates in favor of all the members who may be able to attend. Letters and printed circulars, giving information as to these points, have been sent to Sir Alexander Galt, the high commissioner of the dominion in London, and to Professor Bonney, the secretary of the association. From one of these, signed by the chairman of the local committee, and by Dr. Hunt, as chairman of the committee of invitation, the following extracts are taken :

"The city of Montreal, which has a population of about 150,000 souls, has twice entertained the American association for the advancement of science, - for the second time, in August, 1882, when an attendance of more than nine hundred members and associates was registered, and the association, with its nine sections, found ample accommodation in the buildings of McGill university. . . . We have assurance that the government of the Dominion of Canada will make a liberal grant of money to defray the expenses of members of the British association in crossing the ocean, and that the various railroad and steamboat lines in Canada and in the United States will offer most liberal arrangements to our guests. The Grand Trunk railway will arrange for an excursion of members of the association to the Great Lakes and Chicago; while the Canadian Pacific railroad will give an excursion to the provinces of the north-west, as far as the Rocky Mountains. The city of Montreal, from its climate, its geographical position, and its ways of communication, offers many attractions alike to the traveller and the student. The large and important collections of the geological survey of Canada, gathered during the past forty years, are in the museum at Ottawa; and these, together with extensive collections contained in the museum of the Natural history society of Montreal, and in that of McGill university, furnish ample materials for the study of the natural history of Canada.

"Members of the British association, in coming to Canada, may be assured of a most cordial welcome and generous hospitality, not only from the citizens of Montreal, where every facility will be furnished for their meeting, but from the people throughout the country. It is hoped by the invitation committee that these assurances, and the above statement of the advantages and facilities offered them, may secure a large attendance of the members of the British association at Montreal in 1884."

It is well known that considerable opposition has existed in England to the project of meeting in Montreal; and it is natural that many of the life-members and associates who cannot visit Canada should view it with disfavor: but it is believed that the leading members of the association are of a different opinion, and that the hearty action of the city of Montreal and the dominion government will do much to disarm such opposition as may manifest itself next summer at Southport, where the final decision must be made.

It is to be observed, that in the present year the meeting of the American association, at Minneapolis, is early (Aug. 17); while that of the British association, at Southport, which is, besides, in the immediate vicinity of Liverpool, is unusually late (Sept. 19). This will

allow members of the American association to attend both meetings; and it is stated that the retiring president of the American association, and possibly others of its members, may

avail themselves of this privilege. This may possibly permit arrangements to be made which might substantially unite the meetings of the two associations in 1884, and so prepare for an international meeting in the future. If the meeting of the American association for 1884 can be fixed for some north-eastern city, sufficiently near to Montreal, and can be timed so as to occur a week before or after that of the British association, there can be no doubt that a great number of the members of the latter body would take advantage of the opportunity to enjoy the companionship of their American confrères; while, on the other hand, many of these would gladly spend a few days at the meeting of the British association. In this way it would seem that a greater benefit to science might result than even from an international meeting. There would be time for the complete transaction of the business of both associations. Neither would suffer, either pecuniarily or in the value of its proceedings; and there would be the best possible opportunity for interchange of ideas between the scientific men of the United States, Great Britain, and Canada. Nor is it unlikely that some scientific workers from the continent of Europe and elsewhere may be attracted by a combination so unusual. It may thus be hoped that the proposed meeting of the British association in Canada may not only be one of the most successful that this mother of associations has held, but may inaugurate an epoch of renewed activity and progress in the widelyspread scientific work of the two great associations of the English-speaking race.

MODEL OF THE GIANT OCTOPUS OF THE WEST COAST OF AMERICA. WHILE working on the models of the large Newfoundland squid (Architeuthis princeps) for the Yale and Harvard museums, it was proposed that I should also model the large Octopus of the west coast of America. Nothing was done upon it, however, until the past winter, while preparations were making by the U. S. fish-commission for the International fishery exhibition in London. For this exhibition, Mr. William Palmer, one of the modellers of the National museum in Washington,

nor could make a trip to California for the purpose, the model had to be copied chiefly from specimens preserved in alcohol, and restored according to the best information we could get as to its appearance when living. The largest specimens we could get were badly shrunken by the alcohol; and one of moderate size, with arms about three feet long, was selected; and from this most of the details of the model were enlarged four times.

IMERTONY

On all anatomical points we depended chiefly on Professor Verrill's knowledge of the cephalopods. In the color, size, and position of the body, we were aided by descriptions and sketches by Messrs. W. H. Dall and A. Agassiz, who had seen it alive. I was also guided by my knowledge of Octopus Bairdii, the small species of the east coast, which I had several times seen alive.

The position of the middle part of the body
