30 Mr. G. Gulliver’s Ohsermtions on the Blood Corpuscles 
l-3000th and 1 -2666th. Short diameter, l-6000th, the most 
frequent, and the following were seen, viz. l-6600th, l-6400th, 
and l-5333rd, and l-4800th. Thickness of the edges of the 
disks l-16,000th to 1-12, 000th of an inch. A very few circular 
corpuscles, about 1 -6400th of an inch in diameter, were ob- 
served. Blood obtained from a prick in the skin. 
37. Vicugna, adult male, [Auchenia Vicugna). Disks oval. 
Long diameter most frequently l-4000th of an inch; and the 
following long diameters were observed : l-5333rd, l-3200th, 
l~3000th. Short diameter; the most frequent 1 -6400th ; also 
many varying from 1 -8000th to 1 -5333rd of an inch. A few 
circular corpuscles observed, as in the Dromedary. Blood 
obtained from skin of the leg. 
38. Paco, male, nearly full-grown, [AucJienia Paco), Disks 
oval. Long diameter generally 1 -3200th of an inch; some 
l-4000th, others l-2666th of an inch. Short diameter, most 
commonly 1 -6400th and l-6000th; some of l-8000th, and 
1 -5333rd. A few circular particles observed, as in the Dro- 
medary and Vicugna. ‘ Blood obtained by pricking the ear. 
39. Guanaco or Wild Lama, adult female, [Auchenia 
Glama). Blood obtained from the ear. Disks oval, and 
not differing appreciably from those of the Paco. 
Thus in the Vicugna, Paco, and Wild Lama, the blood 
corpuscles are elliptical*, as the interesting discovery of M. 
Mandl has shown them to be in the Dromedary. In the 
Vicugna the disks are rather smaller than in the Dromedary. 
They all appear to be very thin or flat in relation to their 
size, their edges in the Dromedary being not more than 
1- 16,000th or 1 -20,000th of an inch thick. 1 could see no in- 
dication whatever of a nucleus in any of the corpuscles ; and 
those of the Dromedary were subjected to the action of water, 
acetic acid, and various reagents, with a view to determine 
this point. 
40. Goat, adult female, {Capra Hircus). Common diameters 
of corpuscles l-6400th and l-6665th of an inch ; the following 
sized globules are also very frequent, viz. 1 -7108th, 1 -5333rd, 
and 1 -6000th. Blood from a wound in the neck. 
41. Cashmere Goat, old male, {Capra Hircus, var.). Ave- 
rage-sized corpuscles l-7200th to l-5858th. The corpuscles 
very irregular in size; all the following sizes were very fre- 
quent, viz. I -8000th, 1 -6400th, 1 -6000th; there were also a 
few disks 1 -5333rd of an inch in diameter. Blood from the 
vena cava and from the renal artery. 
* As announced in the Phil. Mag. for December 1839, and in the Dublin 
Medical Press, No. 47. Some observations on the blood and pus of these 
animaU were read at the Royal Med. Chir. Society, Nov. 26, 1839,
