a. Fox-hound Puppy, One day old, a bitch. 1- 3000th and

blood of the vena portae they were generally of the latter size, 
b. Fox-hound Puppy, twelve days old, a bitch. Most

common. Besides blood from the heart, corpuscles were ex- 
amined from the cava and splenic veins. 
24. Red American Fox, half-grown dog, [Canis Vidpes, 
var. Americanus), Common-sized corpuscles 1 -4000th and 
1 -3693rd of an inch in diameter. A few were observed of

25. Black American Fox, a dog, about two-thirds grown, 
[Canis argentatus), l-4000th of an inch most common dia- 
meter of corpuscles: extreme sizes l-5333rd to l-2666th. 
(This animal and the succeeding one came to England together 
from Hudson’s Bay.) 
26. White Arctic Fox, about two-thirds grown, [Canis

The measurements in the genus Canis were all made from 
dried corpuscles obtained from the right ventricle of the 
heart. 
27. Domestic Cat, adult female, [Felis Catus), Blood from 
right ventricle. Most common diameter of disks 1 -4000th of 
an inch ; a few w^ere 1 -4572nd.
