326 Dr. Knox on the Structure of 
pints of clear, and almost insipid water, were found in the cells of 
the second stumach ten days after the death of the animal. He 
concludes, then, that the second stomach is added to the others in 
the camel for the express purpose of a reservoir. To these deserip- 
tions of the stomach of the camel, Daubenton added drawings of in- 
imitable accuracy. The ingenious and elegant popular writer of 
the article “ Menagerie,” in the Library of Entertaining Know- 
ledge, has fallen into a great error by not consulting what Dauben- 
ton has said, and by trusting to the remarks of those whose interest 
and vanity seemed to be gratified by an ill-judged and totally erro- 
neous criticism upon the works of that eminent observer. 
The transverse contraction of the fourth cavity, whereby it is 
obviously divided into two stomachs,—distinguished by this cireum- 
stance, which alone, according to the more generally received views, 
would entitle us to consider this elongated cavity as divided into a 
fourth and fifth stomach,—was discovered by Daubenton, and par- 
ticularly dwelt on by him ; and when he offered it, as his opinion, 
that there exist five stomachs in the camel, he founded that op!- 
nion on views which no real anatomist can possibly call in question. 
2. Stomach of the Lama. 
In his anatomical account of the stomach of the lama, Dr. Knox 
gave to the Society a detailed description of the nerves and of the 
muscular fibres in the first stomach or paunch, developing after- 
wards the succession of tunics and the composition of the cells, and 
alluding more particularly to the slight but ebvious differences in 
the mucous membrane linmg the cells, from that found in other parts 
ef the stomach. The arrangement and number of cells were the 
next objects of his examination. He stated that the paunch had 
two divisions, and was perfectly full of food when dissected. In the 
smaller portion there were 16 rows of cells, eccupyimg a surface 
which varies frem an inch to 12 inch in breadth, and is about 12 
inches inlength. In the greater division there are about the same 
number of cells, but they are much larger and deeper, and they oc- 
cupy a surface of somewhat more than 4 inches in breadth, and 17 
inches in length. 
Dr. Knox, by a drawing, represented to the Society the course of 
the nerves to the muscular fibres, which shut in the cells like the 
strings of a purse. The cells are cavities which have openings to- 
wards the cavity of the stomach, which openings are narrower than 
their capacity within. In the cells of the larger division, the mu- 
cous membrane is still softer in appearance, and more and more un- 
like what it is in other parts of the stomach. In short, in so far 
as regards apparent structure, the author concluded that it must 
obviously perform a separate function. 
The muscular fibres follow ditterent directions, but are chiefly of 
two kinds or arrangements ; in the one, the fibres are arranged in 
planes or membranes ; in the other, they are disposed in large bun-
