eggs. Its viscidity was so great that on pouring it from 
one vessel into another it fell in one mass. It coagulated at the 
temperature of seventy centigrade, also by adding sulphuric 
and nitric acids to it, through their combining with the soda by 
which the albumen was held in solution. Thus this liquor 
gave by the reactives the same result as the white of eggs, 
and it may be considered as nearly of the same composition, 
plus a peculiar odour appertaining to animal matter. The 
quantity of the albumen in proportion to the water is as 6 
to 4. These analyses show that the sub-choroidean effusion 
is formed by albumen and serum in different proportions, 
and in cases of reddish tinge also of the colouring principle of 
the blood. In the human eye I have often found crystallized 
cholesterine in the serous sub-retinous effusion, particularly 
when it was of a yellow colour. 
1th Ohs .—Eye of a horse, dissected July27th, 1837 (No. 172). 
The membrane of the aqueous humour partially corrugated, 
opacity and adhesion to the iris, sub-retinous effusion and 
atrophy. This eye presented the usual alterations which are 
found in the atrophy of the eye of the horse, viz., accumula¬ 
tion of a coloured fluid in a cavity formed posteriorly by the 
choroid, and anteriorly by the retina and the h} T aloid. These 
last membranes are in the same state as in the other cases 
already described. They form the posterior parietes of a 
sac in which are usually contained the capsule and the lens, 
but of the latter there was no trace left. After having cut 
the eye into equal hemispheres, one anterior and the other 
posterior, and having found the alterations indicated, we 
divided the cornea into four parts; it was then easy to sepa¬ 
rate the membrane of Descemet, which was thickened 
throughout its whole extent, presenting towards the middle 
a corrugated aspect. In this part it had lost its transparency 
and was of a whitish colour, while the remainder of this 
membrane was unchanged. The membrane presented, be¬ 
sides, some adherences with the iris, black bands extending 
from the one to the other. The iris was thickened, princi¬ 
pally in those parts corresponding to the diseased parts of 
the membrane, and everywhere it adhered to the anterior 
parietes of the sac formed by the retina and the hyaloid. 
This membrane could easily be separated into the several 
layers of which it was composed, and which were of a certain 
thickness and a whitish colour.
