or Red Disks of the Mammiferous Animals. 29 



disks was from l-4000th to J -3564.th, and 1 -3000th to 1- 2666th 

 were frequent sizes. Corpuscles in the blood of vena portse 

 and right ventricle of the heart apparently identical. 



b. A Kitten sixteen days old. The most frequent size of 

 corpuscles l-^OOOth. From Mr. Siddall's observation. 



28. Serval, adult female, {Felis Serval). 1 -4000th of an 

 inch the most common diameter of the corpuscles. They 

 were very irregular in diameter, l-5000th and 1 -3000th being 

 frequent sizes. Blood from all the chambers of the heart 

 examined, as well as from the renal vein. 



29. Asiatic Leopard, adult male, {Felis Leopardus). Disks 

 very variable in size; l-4800th the common diameter, many 

 varying from l-5333rd to l-3200th. The blood was obtained 

 from the ventricles of the heart, from the renal vein and artery, 

 and from the splenic vein, no difference being apparent in 

 the corpuscles. 



30. Lynx, nearly full-grown, male, (Felis Caracal), Most 

 common diameter of corpuscles l-^SOOth to l-4365th of an 

 inch. Very variable in size, extending from l-60O0th to 

 l-^OOOth. Blood from both ventricles examined. 



31. Norvvciy Lynx, about two years old, {Felis Lynx). Most 

 common sizes l-4'365th to l-4000th. Extreme diameters 

 l-5333rd to l-3554th. Blood from both ventricles. 



32. Coati Mondi, old male, {Nasua fusca). l-3200th the 

 most frequent diameter. Extreme sizes l-4572nd and l-2666th: 

 the former extreme most common. 



33. Red Coati Mondi, adult female, {Nasua rufa). l-4000th 

 and l-3554th the most common diameters of the corpuscles. 

 Extreme sizes 1 -5333rd and l-3200th of an inch. Blood from 

 both ventricles and from the abdominal aorta, in this and the 

 preceding species. 



34. Horse, gelding, aged three years, and another aged 

 five [Eguns Caballus). Blood from jugular vein. The average- 

 sized corpuscles in both l-4800th and l-4.572nd of an inch. 



a. Gelding, twenty-six years old. Same size generally, 

 but more irregular, many being seen as large as 1 -4000th of 

 an inch. In this and the preceding, when collected into 

 rouleaux, the edges of the corpuscles were from 1-1 2,000th 

 to 1-1 45000th of an inch, that is, a rouleau of six or seven 

 disks occupied two spaces of the micrometer. 



35. Ass, old female, {Equus Asimis). Most common dia- 

 meter of corpuscles 1 -4000th of an inch. Blood obtained from 

 the jugular vein. 



36. Dromedary, full-grown male, {Camelus Dromedarius). 

 Disks oval. Long diameter : the most frequent was l-3200th 

 of an inch, and the following were seen, viz. 1 -4000th,
