30 Mr. G. Gulliver's Observations on the Blood Corpuscles 



1-SOOOth and 1 -2666th. Short diameter, l-eOOOth, the most 

 frequent, and the following were seen, viz. l-6600th, l-6400th, 

 and l-53S3rd, and l-'iSOOth. Thickness of the edges of the 

 disks l-16,000th to l-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 Vicugyia). Disks oval. 

 Long diameter most frequently l-4000th of an inch; and the 

 following long diameters were observed : l-5S33rd, l-3200th, 

 l~3000th. Short diameter; the most frequent 1 -6400th ; also 

 many varying from 1 -8000th to l-5S33rd 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, [Auchenia 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 

 Ghana), Blood obtained from the ear. Disks oval, and 

 not diflering 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 

 l-16,000th or l-20,000th of an inch thick. I 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 pomt. 



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, l-5333rd, 

 and 1 -6000th, Blood from a wound in the neck. 



41. Cashmere Goat, old male, [Cajora Hircus, var.). Ave- 

 rage-sized corpuscles 1 -7200th to l-5858th. The corpuscles 

 very irregular in size; all the following sizes were very fre- 

 quent, viz. l-8000th, l-6400thj l-6000th; there were also a 

 few disks I-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 

 animals were read at the Royal Med, Chir. Society, Nov. 26, 1839.
