gland. Herein it is that the veins commence their 

 share in the work of circulating the blood afresh, as 

 we shall see in the sequel, and the lymphatics obtain 

 the watery particles into which the morbific matter 

 of those solids are converted. 



In blood horses (natives of hot climates), as we 

 have seen, tendon supplies the place of muscle, or 

 flesh, upon the limbs particularly, which are always 

 finer than those of other breeds ; this accounts why 

 our fleshy horses in sultry weather, or hot stables, 

 feel the greatest lassitude, even to weakness, whilst 

 those of full blood seem invigorated by the same 

 circumstance. When, however, the atmosphere of 

 the stable be moist as well as hot, both breeds suffer 

 equally in one way or another ; laxity of fibre and 

 profuse perspiration, with weakness, follow, and 

 these producing an obnoxious effect upon the ex- 

 crematory organs, occasion in stables those stinking 

 ammoniacal vapours that destroy the lungs, by dis- 

 posing them to contract inflammation. 



28. Besides the Glands just alluded to, that 

 are situated in and about the solids and more se- 

 cluded parts, and are so small and concealed as to 

 be scarcely exposed to the sight or touch, unless 

 when inflamed and enlarged by disease ; other 

 larger and more evident ones occupy the hinder 

 part of the animal, of which we shall speak in their 

 place. They are, 1st, the liver; 2d, the kidneys; 

 and 3d, the testicles ; the functions of each being 

 tolerably well known. See sect. 52 — 55. and chap. iii.
