IN THE SOCIETY’S COLLECTION. 97 
All the contents of the stomach were of a green colour; and 
two small boluses of hay which it contained were tinged deeply with 
' Four more coins, deeply corroded and greenish-black, were found 
in one of the intestinal ceca, together with a few stones. There were 
also a few stones in the other cacum; and the mucous membrane of 
both ceca was congested and unhealthy in appearance, which was not 
the case in the stomach to any extent. 
There were no symptoms of jaundice, which frequently accompa- 
nies copper poisoning. The liver appeared healthy, except that scat- 
tered abont were a few dense white lumps about the size of peas, 
mostly near the surface: it weighed 3 1b. 9 0z. No gall-bladder was 
present. 
The spleen was very small, and altogether weighed just under 
2 oz. There was very little healthy tissue preserved, it mostly con- 
sisting of spheroidal dense masses of matter which were about the 
size of chestnuts, and by protruding beyond the general surface 
produced an appearance of knobs. These masses, on cutting through 
the capsule, separated entirely, and were then seen to be rough and 
altogether very like urinary calculi; they were of a fawn-colour. The 
organ was situated nearly in the middle line, just above the kidneys. 
The heart weighed 1 Ib. 7 oz., and gave origin to two carotid 
arteries, one from each main branch, which ran to the head, a dis- 
tance of about 3 feet 6 inches, side by side, in front of the cervical 
vertebre, in the groove formed by the anteriorly projecting processes 
of those bones; and they never showed any tendency to unite or Page 358. 
cross one another. They were thickly covered by the anterior cervical 
muscles, and sent off symmetrical branches.* 
Superficially on each side of the neck ran a vein with the pneumo- 
gastric nerve; but that on the left side was not bigger than a crow- 
quill, while that on the right had a diameter at the lower part of 
the neck of two-thirds of an inch. This condition is constant in many 
birds. 
This right (practically the only) jugular vein, after coursing 
abont half or a little more up the neck, sent two branches to the 
head, the second running in the middle line, just behind the trachea 
and in front of the cesophagus, the first being a direct continuation of 
- the main trunk. 
The intestinal canal was 34 feet long; and the two ceca, each 
* The presence of the two carotids in this bird, while there is only one in Rhea, 
would require that they should be far separated in Nitzsch’s classification of birds 
according to the number of these vessels—the Ostrich being in his first class, with a 
carotid from each main aortic branch, and the Rhea in the fourth class, with only 
the left developed. See Nitzsch’s “‘ Pterylography” (English edition), App. p. 171.
