the shells also are very little altered : the epidermis or 
fine cuticle of the shell is in the prominent parts lacerated, 
and the white lime is apparently in a small degree softened : 
in this state they appear to be voided, as they were much 
in the same state in the extreme gut. These fishes, like 
other fat subjects, seem to require very little food. 
The stomachs of other Trout that I have examined 
contained these and other shelly animals, such as cads *■ 
with stony and wooden cases, &c., but I did not meet with 
any separate remains of any of the animals so as to identify 
their species. From what John Hunter observes, we may 
conclude that the size of the stomach is owing to its de- 
lighting in coarser food than others.
