or Red Particles of the Mammiferous Animals. 
1 -4500th, l-4572nd, and l-4800th. Extreme diameters, 
l-6000th and l-4000th. In the serum, a great many of the 
disks l-6000th to l-5333rd of an inch. Blood from a vein 
of the fore foot. 
92. Wolf, {Canis Lupus,) adult male. l~3554th, ] -3635th, 
1 -3692nd, all very frequent diameters. Extreme sizes 1 -4570th 
and 1- 3000th. Blood from a prick of the ear. 
93. Jackal, [Canis mesomelas,) adult female. The following 
diameters very common : l-3552nd, l-3600th, l-3693rd, 
1 -3790th. Extreme sizes l-4570th, l-3000th. Blood from 
a prick of the ear. 
94. Two Spotted Paradoxure, {Paradoxurus hinotatus,) 
a female nearly full-grown, from Western Africa. The follow- 
ing sizes frequent: l-4572nd, l-4800th, and 1 -5052nd of an 
inch. Extreme diameters l-6000th and l-3555th. Blood 
from a prick of the tail. 
95. Striped Hyaena, {Hyaena mlgaris,) female not quite 
full-grown. l-4000th, l-3764th and l-3552nd, common dia- 
meters. Extreme sizes l-4800th and l-3000th. Blood from 
a vein of the ear. 
96. Lion, [Felis Leo,) from Africa, nearly full-grown. The 
most common diameters l-4500th and l-4365th of an inch. 
Extreme sizes l-5800th and l-3554th. Blood from a prick 
of the ear. 
a. Lioness, about two-thirds grown. Some corpuscles ob- 
tained from the cutaneous vessels of the leg gave the same 
measurements. 
97. Puma or Silver Lion, {Felis concolor,) from South Ame- 
rica, full-grown male, l-4572nd, l-4500th and l-4440th, the 
most frequent diameters of the disks. Extreme sizes l-5800th 
and 1-35 5 4th. Blood from a prick of the ear. 
98. Tiger, {Felis Tigris,) from India, a female, full-grown. 
Common sizes l-4440th, l-4210th, and l-4268th. Several 
also of l-4000th. Extreme diameters 1- 5333rd and l-3428th 
of an inch. Blood from a vein of the ear. 
The size therefore of the blood corpuscles of these larger 
species of the genus Felis is very nearly alike^\ In some of the 
smaller species, as the Cat (27.), Serval (28.), and Lynx 
(30.), the disks have much the same diameter, as I infer from 
frequent examinations. Mr. Siddall too, before he was ac- 
quainted with the result of my observations, came to the same 
conclusion, from several trials with the blood of the cat, as 
compared with one specimen of that of the tiger. In some 
blood obtained during life from the femoral vein and from the 
femoral artery of a cat, about a third-grown, the disks most
