For the gratification of our readers, we shall give room to another extract from the description of this beautiful and romantic scene.

"[descended with regret from a dele&table mountain, and came again within the pale of the park, at the place I left it, near the ruin ; where in the midst of a grove of chefnuts, the path finds its way, and then steals between a multiplicity of knotty, crooked oaks, along the side of a narrow valley, capricioufly wooded in the bottom only, to a feat ornamented with shells, with this infcription in the same fancy :


• The seat of contemplation,

All is vanity.' . This feat rises in the midst of fylvan beauty, and no Stuation in the world can more aptly agree with the first line of the inscription ;--it is formed exactly for it, retired, folitary, and serene--indeed, the whole of the walk from the ruin, is unparalleled : -no valley was ever more happily diversified po'taste ever shewed itself more powerfully--we here see how surpafling that part of gardening is, that never violates the Jaws prescribed by nature; and if a designer, who might happen to have (as is sometimes the case) some lively sparks of genius about him, was to visit this place, and be attentive to its charms, he possibly, might gather fome laurels in an imi. 'tation—but the worst part of it is, most of these gentlemen of the profeflion, seldom think any thing fine enough, and will dip their pencils into carmine, when the most simple colour would do a thousand times better.

• I rambled in delight through this Tempean recess, catching its influence in the feelings of the softest tranquility :-every step I took, whether I descended into the obscure, or rose again. to the more fprightly, I thought the scene still improved, till I found myself within the vicinity of perfection itself, at

6 The H ER MIT A GE, & One knows not how to reconcile an hermitage, or a cote tage, standing within the polithed park of a nobleman: there is an incongruity in both ; and neither, in my opinion, should be countenanced in such places.

• However, this hermitage, or call it what you will, iswell enough adapted to the scenery about it, being rudely formed with chumps of wood, and jagged old roots, jambed together, and its interstices simply filled with moss: the for is neatly paved with small pebbles, and a matted couch goes round it.

• A door from this leads into another apartment much in the same dress; every thing within, and immediately about it, carries the face of poverty, and a contempt of the vain superfluities of the world, fit for the imaginary inhabitant, whom we are to suppose defpises the follies and luxuries of life,, and who devotes his melancholy hours, to meditation and a rigid abstinence.

• Within the first room are these well adapted Knes from the Il Penferofo of Milton:

• And may at last my weary age
Find out the peaceful hermitage ;
The hairy gown and mofly cell,
Where I may fit and rightly spell
Of every star that heav'n doth shew,
And every herb that fips the dew:
Till old experience do attain
To something like prophetic strain,
These pleasures melancholy give,

And I with thee will chuse to live.

There appear from the door of this mofly cell, two perfpe&tive peeps at the diftant country; one of them over the spreading branches of the trees in front, and the other under them-little fancies of this fort, in places To folitary, where they do not expose the fituation, but only tincture it with a ray of chearfulness, are very justifiable.

• I suppose there is not in the whole of thefe domains, nor, I may venture to affirm, in any other, a recess to be found, capable of exciting more agreeable feelings in the breast of a man of take, than this before us.-Nature and art co-operate so happily, that to diftinguish one from the other, requires a judgment little inferior to that employed in the execution of it: the one seems to have exerted all her powers in gwing the most random inequalities; the other in the excellent dif position of the groves, clumps, or fingle" trees that adorn them.

• Excepting the two perspective views before mentioned, the whole is close, depending on its own parts, which though sew, admitting only' of a glimpse of the deep tree-filled rural valley, water, flants of lawn and precipitate woody hills, are indescribably picturesque.'

Thomfon, too, had his favourite walk in this Elysian re. treat ; to'whose memory likewise' his lordship devoted an ele. gant building, of an octagonal form, with the following infcription.

With respect to the succeeding object of attention, the beautiful Leasowes, it was formerly the seat of Mr. Shenstone, and at“ present, of Edward Horne, esq. But for the account of those places, we must refer to the Letters, where they are painted in a lively and agreeable manner, and the description interfpersed with observations which indicate sensibility and taste.

Experimental Inquiries : Part the Third. Containing a Defcription

of the red Particles of the Blood in the Human Subject and in other Animals; with: an Account of the Strukture and Offices of the Lymphatic Glands, of the Thymus Gland, and of the Spleen. By Magnus Falconar. 8vo.' 5s. in boards. Longman. N this work, Mr. Falconar prosecutes the Inquiry concern.

ing the composition of the blood, which had been begun by the late ingenious Mr. Hewfon. He informs us, that during an intimacy of three years, he had frequent opportunities of discoursing with that gentleman on the subject, and be. coming perfectly acquainted with his ideas. Besides which, Mr. Falconar frequently repeated many of the experiments that had been instituted by his friend, and thereby not only attained a more complete knowledge of the doctrine, but has been confirmed in the cpinion that it is founded in truth.

The first chapter of this inquiry was written by Mr. Hewson, and published in the sixty-third volume of the Philosophical Transactions. The author there maintained, in opposition to


preceding writers, that the particles of blood, instead of being spherical, were in reality fat bodies. This discovery he ascribed to his having diluted the blood before he fubjected it to the mi. croscope, the omiflion of which expedient had rendered the composition of the blood indiscernible to former observators. In performing the dilution, however, he did not employ water, which would have diffolved the particles, but the serum of the blood. After viewing the particles distinct from each other, he observed that they were perfectly fiat; and that the dark spot in the middle, which father de la Torré imagined to be a hole, was not a perforation. In answer to an objection which might be urged, namely, that though thofe particles appear to be flat out of the body, they retain a fpherical figure within the vessels, Mr. Hewson affirmed, that he had repeatedly observed them with their sides parallel, like a num. ber of coins laid one against another, whilst circulating in the small vefsels between the toes of a frog, both by the fular microscope, and the other which he used.

In the second chapter, Mr. Falconar enters on an anatoinical and physiological disquisition concerning the structure of the lymphatic glands, in which we meet with the following obfervations on the properties of the fluid that is found in those parts of the body:

• The existence of a white thick mucus-like fluid, in the lymphatic gland, has been long generally known to anatomists, and is particularly remarked by M. de Haller ; bur the properties of this fluid seem to have been entirely overlooked and neglected.

• This may perhaps have been owing to the fame cause, that the shape of the particles of the blood, till lately, has been so little known, viz. the want of diluting this liquor ; for it we examine this fluid in the natural state, we find it a homogeneous mass, discovering nothing of its compofition, or properties. But if we dilute it with a solution of Glauber's falts in water, or with the serum of the blood, and view it with a lens of the z's of an inch focus, as formerly mentioned in the experiments on the blood, we then observe the following ap. pearance.

• Numberless small, white, folid particles, resembling in size and Mape those central particles found in the veficles of the blood, are to be seen distin&ly g'iding down on the fage of the microscope, and if we dilute it sufficiently, we can examine them separately, and view them as distinäly as we can the particles of the blood.

• These particles found in the lymphatic glands, likewise agree remarkably in their properties with the central pas seles



found in the vesicles of the blood, not only as to fize and shape, but also in being insoluble in serum, or a solution of any of the neutral falts in water (except putrefaction takes place), and are like the blood soluble in water, and in the same order. These particles are by the lymphatic vefsels taken into the course of the circulation, and mixed with the blood, where they are for a time retained, to be again fepa. rated from it, as we shall see afterwards in our inquiry into the anatomy of some other parts.' .

The third chapter treats of the situation and ftru&ure of the thymus gland, a part, the function of which not being obvious, some physiologists have considered as of no use in the animal ceconomy. From the experiments here related, however, the following plausible conclusions are drawn, viz. that one use of the thymus is to fecrete from the blood a fluid, containing numberless small folid particles, fimilar to those found in the lymphatic glands; and that the lymphatic vefsels arising from the thymus convey this fecreted fluid through the thoracic duct into the blood-vefsels, and become the excretory duets to this gland. That the structure and uses of this gland are similar to those of the lymphatic glands, to which it may be considered as an appendage. In confirm ation of this doctrine it is observed, that the thymus exists only during the early periods of life, at which time those particles appear to be chiefly wanted.

In the succeeding chapter, the author examines with equal accuracy the situation and structure of the spleen ; and from the experiments related, proceeds, in the next division of the Inquiry, to give an account of the manner in which the red particles of the blood are formed, conformable to the observ ations that have been made.

The theory of this inquirer is, that the central particles of the blood are chiefly formed by the lymphatic veffels and glands, and that the office of the spleen is to secrete the ve. sicular part. The novelty of the doctrine, as well as its importance to physiology, induces us to lay before our readers, the author's argunents in its favour,

• It may then reasonably be asked, how is the red blood formed when the spleen is taken out, if the spleen is the vifcus intended by nature to form the red blood? This objection will militate equally strong against any other use the spleen is sup. posed to have ; for that the spleen may be taken out, and the animal fuffer but little inconveniency, by no means prove it to be useless, but it proves that some other part is capable of performing its office. Every philosopher must entertain too, exalted an idea of nature, to believe that any part of the
