138 OBSERVATIONS ON THE ANATOMY OF 
tion on the left side like a caecum, 3 inches in length. The 
cardia was thick and muscular, the stomach smooth inter- 
nally, and with thin parietes, and the pyloric extremity was 
suddenly contracted by a narrow ring at its entrance into 
the very wide commencement of the duodenum. The sto- 
mach lay chiefly on the left side, and tapered regularly 
from the left to the right extremity ; when moderately in- 
flated, it measured 8 inches in a straight line from left to 
right. The small intestines, from the pylorus to the cae- 
cum coli, measured SI feet ; the caecum coli measured 19 
inches in length ; and the large intestines, from the caecum 
to the anus, were 11 feet long. The commencement of the 
duodenum was so much dilated, as to form a small caecum 
an inch long above the pyloric orifice, the dilated part of 
the duodenum continued about 4 inches from the pylorus. 
The rest of the small intestine had a uniform appearance, 
and was about an inch in diameter. The ilium terminated 
by a valvular orifice, in a wide and convoluted caecum, 2| 
inches in diameter, deeply divided by internal transverse 
plicae, marked externally by longitudinal bands, and ex- 
tending from the left to the right iliac region. The caecum 
formed two complete spiral turns, and tapered regularly to 
its shut extremity. The passage leading from the caecum 
into the colon was placed near that of the ilium, at the 
wide commencement of the caecum. The first ten inches 
of the colon were nearly as wide as the caecum, and turned 
between its convolutions. This dilated part of the colon 
exhibited a corded appearance, produced by numerous 
small longitudinal plicae of the inner membrane. The whole 
remainder of the colon and the rectum had the same dia- 
meter and general appearance as the small intestines. Im- 
mediately on escaping from the spiral turns of the caecum, 
the colon doubled itself, and formed a small circular disk 
of convolutions lying in the same plane, and connected to-
