foot — viz., the lateral cartilages, sensitive frog, coronary liga- 

 ment, sensitive lamina, and sensitive sole. 



The lateral cartilages are two thin plates, composed of hyaline 

 cartilage in the middle, partaking more of the nature of fibro- 

 cartilage towards the borders. They are of an irregular qua- 

 drangular form, and surmount the wings of the cofhn bone. The 

 sensitive portion of the foot is attached to the inner surface of 

 the hoof. The sensitive frog occupies the posterior and central 

 parts of the foot, filling up the iri'egular space between the late- 

 ral cartilage, flexor tendons, and os pedis. The coronary sub- 

 stance, or coronary band, is that vascular structure which occu- 

 pies the cutigeral groove on the superior border of the wall. The 

 sensitive laminie are the continuations of the coronary substance, 

 and are attached to the coffin bone by a dense, fibrous mem- 

 brane. The sensitive sole, continuous with the sensitive laminae 

 and frog, is firmly attached to the coffin bone; like the sensitive 

 laminse, it is made up of a fibro-vascular membrane, clothed by 

 a continuation of the corum, covered by villi, which secrete the 

 horny sole. The perioplic ring is composed of papillae like those 

 of the coronaiy cushion, but smaller in size, and it is by its 

 agency that the periople whidi covers the exterior of the wall is 

 formed. 



THE BLOOD. 



The blood, as it exists in the living body, is a red, homogene- 

 ous, alkaline fluid, of saltish taste and faint odor; its specific 

 gravity is 1052-1058. It consists of minute, solid bodies, the 

 corpuscles floating in a liquid, the liquor sanguinis. The cor- 

 puscles are of two kinds — the red and the white, or colorless; 

 the former, by far the more numerous, exist in varying propor- 

 tions. The red corpuscles are circular biconcave discs of 

 1.4000th part of an inch in diameter, their average thickness 

 being about one-fourth of this. 



The white corpuscles are larger than the red, spheroidal in 

 shape. Some of them are smaller than the red, and have a lower 

 specific gravity. They possess one or two nuclei, which are
