198 Mr. Gulliver’s Obsermtions on the Blood Corpuscles, 
the animal a day or two after death, the variation is within 
the limits that may occur in the same species. 
122. Black-backed Papio, or Indian Ape, {Papio mela- 
notus,) a male. Common diameter of corpuscles l-3482nd of 
an inch; extreme sizes l-4570th and 1 -2666th. Blood from 
the axillary vein after death. 
123. Wanderoo Monkey, [Papio silenus^) a full-grown male. 
Frequent sizes of corpuscles l-3600th, ] -3552nd, and 1 -3270th 
of an inch. Extreme diameters l-4570th and l-2666th. 
Blood from the left ventricle of the heart. 
124. Chameck Spider Monkey, (Ateles suhpentadactylus^) a 
female about two-thirds grown. The following diameters 
most frequent: l-3790th, l-3600th, and l-3429th of an inch. 
Extreme sizes 1 -4920th and 1 -2900th. Blood from a prick 
of the fore hand. 
125. Black Spider Monkey, [Ateles ater,) an adult male. 
All the following sizes very common : l-3429th, l-3528th, 
l-3555th, l-3600th, l-3693rd and l-3792nd. Extreme dia- 
meters l-4555th and l-3000th. Blood from a prick of the 
fore hand. 
126. Weeper Monkey, [Cehiis apella,) a female nearly full- 
grown. l”3600th, l-3554th, l-3429th, and l-3368th ; most 
common sizes. Extreme diameters 1 -4800th and l-2666th 
of an inch. Blood from a prick of the fore hand. 
The measurements slightly smaller than afforded by the cor- 
puscles of C. capucinus (5.), but as the blood was procured 
from a dead specimen of the latter, the discrepancy is not 
greater than may be often observed under similar circum- 
stances in one species. 
127. Squirrel Monkey, [Callithri/v sciureus,) a male about 
two-thirds grown. The following sizes all very frequent : 
l-3790th, l-3693rd, l-3600th, and 1 -3552nd. Extreme dia- 
meters, l-4800th and 1 -3200th. Blood from a prick of the nose. 
The blood of the Toque Monkey (81.) was obtained from the 
heart of a dead specimen. The corpuscles, procured from a 
wound in the tail, of a healthy full-grown male afforded the 
following measurements, viz. dry, l-3764th, 1 -3600th, and 
1 -3552nd. In the serum many disks of the same magnitude 
were observed, besides a large quantity of smaller size, viz. 
from l-6000th, to 1 -5333rd of an inch, though the blood 
was carefully secured in a small glass tube and examined 
within an hour after it was taken from the animal. 
128. The Mole, [Talpa Europcea,) recently killed, smallest 
disks about l-5000th, the largest about l-4000th of an inch. 
Blood from the heart. 
For this observation I am indebted to Dr. Davy.
