198 Mr. Gulliver's Observations 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- 

 7iotus,) a male. Common diameter of corpuscles l-34<32nd 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 subpentadactijlus,) a 

 female about two-thirds grown. The following diameters 

 most frequent: l-3790th, l-3600th, and l-3429th of an inch. 

 Extreme sizes l-4'920th 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, 

 1 -3555th, 1 -3600th, 1 -3693rd and l-3792nd. Extreme dia- 

 meters l-4555th and l-3000th. Blood from a prick of the 

 fore hand. 



126. Weeper Monkey, [Cehus apella,) a female nearly full- 

 grown. l-3600th, l-3554<th, l-3429th, and l-3368th; most 

 common sizes. Extreme diameters l-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, [Callithrix sciureiis,) 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 l-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 healthv 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 Europcca,) 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.
