29 
or Red Disks of the Mammiferous Animals, 
disks was from l-4000th to J-3564-tli, and 1 -3000th to 1- 2666th 
were frequent sizes. Corpuscles in the blood of vena portae 
and right ventricle of the heart apparently identical. 
h, A Kitten sixteen days old. The most frequent size of 
corpuscles l-4000th. 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 l-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-4800th to l-4365th of an 
inch. Very variable in size, extending from 1 -6000th to 
l-4000th. Blood from both ventricles examined. 
31. Norway Lynx, about two years old, {Felis Fynx), Most 
common sizes l-4365th to l-4000th. Extreme diameters 
l-5333rd to l-3554th. Blood from both ventricles. 
32. Coati Mondi, old male, {Nasua fiisco). 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 1 -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 
?iSQ{Equus Cab alius). Blood from jugular vein. The average- 
sized corpuscles in both l-4800th and l-4572nd 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 4,000th of an inch, that is, a rouleau of six or seven 
disks occupied two spaces of the micrometer. 
35. Ass, old female, {Eqiius Asinus). Most common dia- 
meter of corpuscles l-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 1 -3200th 
of an inch, and the following were seen, viz. 1 -4000th,
