32 Mr. G. Gulliver’s Observations on the Blood Corpuscles 
ably distinct and characteristic, and I believe unlike any 
hitherto described in the animal kingdom. They are generally 
acutely pointed at the ends and gibbous in the middle; some- 
times they are not curved, and then, to use a botanical term, 
they present a lanceolate figure. A more particular descrip- 
tion of them, with drawings, is in preparation. 
49. Napu Musk Deer, adult female, {Traguliis Javanicus^). 
Average size of disks 1- 1 2,000th of an inch. Extreme diameters 
1 -15,000th and I -9600th. Blood examined from a prick of 
the ear, also from a small vein of the leg. 
Hence the blood disks of this beautiful little animal are 
smaller than those, hitherto described, of any other mammal. 
They were remarkably distinct, and very well seen in dry 
specimens, also diluted with serum or urine. 
50. Pig, about half-grown, {Sus Scrofa). Common dia- 
meters l-4000th and l-3728th. Extreme sizes l-5333rd and 
l-3200th, and the corpuscles generally very variable. The 
blood examined was arterial and venous mixed. 
51. Elephant, male, apparently an adult, {Elephas Indicus), 
Most frequent diameters of disks l-3000th, l-2666th, and 
l-2462nd of an inch. Other sizes, 1 -3329th, 1-29 10th, 
1 -2823rd, and 1 -2286th. Blood obtained from a vein in the ear. 
Consequently the blood corpuscles of this animal are larger 
than any hitherto described in the mammalia, being consider- 
ably larger than in man. But a reference to the compara- 
tive magnitude of the blood disks of the horse and the bat, 
and some species of Miis, will show how little relation there is 
between the size of the animal and the diameter of the red 
particles. In the mouse for instance, they are larger than in 
the horse. 
52. Rhinoceros, full-grown male, {Bhinoceros Indicus)* 
Common size of disks 1 -4000th and 1 -2554th. Many were 
observed with diameters of l-4572ndand l-3200th of an inch, 
with of course every intermediate gradation of size. Blood 
from a prick in the nose. 
53. Common seal {Phoca vitulina), 1 -3200th the most fre- 
quent diameter. Extreme sizes l-3554th and l-2666th. The 
disks very regular in size. Blood from prick of caudal fin. 
The particles are slightly larger than in the adult human 
subject, and approach in appearance to corpuscles of the 
monkey’s blood.

Moschus Javaniciis of Pallas. Since my observation of the singular blood- 
disks of this anitnal was |)ul)Iished, Professor Owen has given an account 
of them in another sj)ecies {M.pygmcous)^ in which they seem to be equally 
small, as he remarks he had anticipated.
