or Red Particles of the Mammiferous Animals, 
129. Grisly Bear, {fjrsus ferox^) a female about half- 
grown. Most common diameters l-3o40th and l-3552nd 
of an inch. Extreme sizes 1 -4570th and l-3000th. Blood 
from a prick of the nose. 
130. Badger, {Meles mlgaris,) an old male. All the fol- 
lowing sizes very common: l-4128th, l-4000th, l-3973rd, 
l-3810th, and l-3693rd. Extreme diameters 1 -5333rd and 
1 -3200th of an inch. There were besides some of the very 
small circular particles as in the genus Sciurus, Blood from 
the integuments of the thigh. 
131. Common Jackal, [Canis aureus^) an old male. The 
corpuscles, dried quickly, afforded the following measure- 
ments: l-4000th, l-3764th, and l-3840th most frequently, 
the extreme sizes being l-4800th and l-3200th of an inch. 
In the serum, examined within two hours after they were 
obtained, 1 -4800th was the most common diameter, and the 
extreme sizes l-6000th and l-3200th. Disks of the last, or 
largest size, as well as of l-3555th, were not unfrequent, ge- 
nerally collecting together quickly into rouleaux, from which 
it was seen that the thickness of the edges of these corpuscles 
was l-14,000th of an inch. The smaller particles, though 
much more abundant, did not arrange themselves together 
by their flat surfaces, and indeed could hardly be seen edge- 
wise. 
The blood was obtained freely from a puncture in a vein 
of the hind leg ; and the above facts are merely mentioned 
as exemplying the variations which may often be observed in 
the corpuscles only a short time after the blood has been - 
removed, with every care, from various mammals. 
132. African Civet Cat, (Viverra civetta^) adult male. 
l-46l5th, l-4360th, l-4000th, and l-3552nd of an inch all 
frequently observed. Extreme sizes 1 -6000th and 1 -3200th. 
The corpuscles in this instance, therefore, very variable in 
magnitude. Blood from a prick of the tail. 
In another adult male, after death, the corpuscles were 
also extremely variable in size, as the following were all com- 
mon, viz. l-5333rd, l-4760th, l-4500th, 1-441 2th, l-4365th 
and 1 -4000th; the extreme measurements being l-6000th 
and 1-S200th of an inch. Blood from the different cavities 
of the heart, from the coronary veins, and from the portal vein. 
133. Javanese Ichneumon, [Herpestes Javanicus^) a full- 
grown male. All the following sizes common: l-4800th, 
l-4924th, 1-5 142nd, and 1-5 120th. Extreme diameters 
l-6000th and 1 -4000th. Blood from a wound at the end of 
the tail. 
134. Chetah or Hunting Leopard, {Felisjubata,) an adult
