19. Paradoxure Gennet, adult, [Paradoxurus typus). Most 

 frequent size l-5331st. Extreme diameters 1-G600th and 

 l-4572nd. Size of corpuscles more regular than in the pre- 

 ceding. Blood from a prick of the tail. 



20. Gray \chne\ivc\oxi {Herpestes griseus), adult male. Most 

 frequent diameter l-4572nd of an inch. Extreme sizes 1 -6000th

21. Domestic Dog, old mongrel, [Canisfamiliaris). Com- 

 mon diameter of corpuscles l-4000th to l-3200th of an inch. 



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

 l-2666th the most common diameters of the corpuscles. In the 

 blood of the vena portae they were generally of the latter size, 



h. Fox-hound Puppy, twelve days old, a bitch. Most 

 common diameter of the corpuscles l-3000Lh and l-2885th 

 of an inch. Extreme sizes l-4000th and l-2666th. 



c. Mongrel Puppy, four months old, a bitch. All the fol- 

 lowing diameters common, viz. l-3693rd, l-3554<th, l-34<29th 

 and l-3200th.

 straliensis). Most common size of corpuscles l-3200th and 

 1 -3000th; l-4000th and l-2666th were seen, but rarely. 



23. Fox, old bitch, [Canis Vulpes), The following sized 

 corpuscles were frequent, viz. l-4572nd, l-4365th, 1 -4000th, 

 and l-3653rd; the third diameter (l-4000th) was the 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 Fidpes, 

 var. Americanus). Common-sized corpuscles 1 -4000th and 

 1 -3693rd of an inch in diameter. A few were observed of 

 l-5333rd; and l-3200th was rather a frequent diameter. 



9,5. 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 

 lagopus). Same sizes as in the preceding. 



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 Cains). Blood from 

 right ventricle. Most common diameter of disks l-4000th of 

 an inch ; a few were 1 -4572nd. 



a. A Kitten one day old, female. The common size of
