Página 449 - French beans ; or, rather, American beans. The herbalists call them kidney-beans, from their shape and effects; for they strengthen the kidneys. They are variegated much, — some being bigger, a great deal, than others; some white, black, red, yellow, blue, spotted : besides your Bonivis, and Calavances, and the kidney-bean that is proper to Ronoake. But these are brought into the country: the other are natural to the climate.
Página 656 - Stead of pottage and puddings and custards and pies, Our pumpkins and parsnips are common supplies : We have pumpkins at morning and pumpkins at noon ; If it was not for pumpkins we should be undone.
Página 522 - Further experiments are, however, needed on this head, for any ordinary washing would be very ineffective compared with the prolonged soaking the tide would effect in the case of a limpet (like the one just mentioned) living some distance below high-water mark. Still some limpets live so near this last that they are covered but a very short time, and yet these remain on their scars during that time. Hence I think some other motive probably induces them to remain firmly fixed to their scars when under...
Página 529 - The lungs and the liver are easily and successfully injected. I have been less successful in injecting the organs that send away their blood current through the portal vein; but I have no doubt that they too may be injected. Triple injections of the liver may be made by first injecting the hepatic artery with a green mass until the whole liver assumes a green tint, and afterwards injecting the portal vein and the hepatic vein with red and blue as above directed. The same apparatus may be employed...
Página 450 - Okindgier, called by us beans, because in greatness and partly in shape they are like to the beans in England, saving that they are flatter, of more divers colors, and some pied. The leaf also of the stem is much different. In taste, they are altogether as good as our English peaze.
Página 697 - The present paper referred more particularly to a remarkable Jurasso-cretaceous flora recently discovered by Dr. GM Dawson in the Rocky mountains, and to intermediate groups of plants between this and the Middle Cretaceous, serving to extend greatly our knowledge of the Lower Cretaceous flora, and to render more complete the series of plants between this and the Laramie. The oldest of these floras is found in beds which it is proposed to call the Kootanie group, from a tribe of Indians of that name...
Página 734 - Mr. Charles E. Putnam enters a vigorous and well-written protest against the criticisms and insinuations which have been made against the character of the discoverer and the authenticity of the elephant pipes in the museum of the Davenport Academy. The article is racy reading, and incidentally gives strong arguments against the desire for centralization in science shown in certain quarters. It will be found impossible to concentrate all science in any one clique or city. Our local societies and scattered...
Página 520 - Indeed, limpets are often serviceable to one another by thus clearing away esculents growing upon their shells. To secure a dinner, a good deal of licking is requisite, and perhaps this habit may help to account for the inordinate length of the tongue-ribbon. Certainly it must be used up at a very great rate. But this is not the only, though I believe' the chief, way in which the limpet feeds. Those individuals which live near large sea-weeds, such as Fucus, feed extensively upon them, as their gnawed...
Página 529 - ... 37. — Apparatus for making double injections. with the bottle F by the tubes D and C. Each of the bottles B and R has a tube, which, starting from near the bottom, passes through the cork, and is, a little above this, bent at right angles. With these are connected the rubber tubes, H and I. Now when water is allowed to flow into the reservoir mentioned above, the air is forced out through A into F, and thence along the tubes D and C into B and R. As soon as the pressure in these bottles becomes...
Página 713 - ... are footless, while the tenth bears the fully developed anal or fifth pair of genuine proplegs. " While these two pairs of tubercles differ from the normal legs in being much smaller and without a crown of curved spines, they are protruded and actively engaged in locomotion, and in situation, as well as the presence of the basal tufts, are truly homologous with the normal abdominal legs. " When we turn to the work of Kowalevsky on the...
