Fig. 1. The stomach of the viper laid open, to show its in- 
ternal surface. 
Fig. 2. The stomach of the turtle, exposing one half of its 
cavity . 
Fig. 3. The stomach of the frog, exposed in the same 
manner. 
Fig. 4,. A longitudinal section of the stomach of the blue 
shark. This fish was caught at Hastings, and purchased for 
me by my friend Col. Bothwell of the Scotch Greys, who 
happened to be there. 
It is proper to remark, that previous to inverting the different 
stomachs, an opening was made at the cardia, to prevent the 
inversion from injuring the internal parts ; this opening was 
afterwards sewed up in such a manner as to be air-tight, and 
then the stomach was distended. 
Where the parts are not represented of their natural size, 
the proportions in which they are reduced are marked upon 
the Plate.
