NOTES AND CORKESPONDENCE ON THE SALMON AND TROUT. 371 



B— Oi^ STOMACHS OF SALMON AXD THEIR CONTENTS. 

 1. — ON THE CiECAL APPENDAGES OF THE STOMACH. 



New Haven, February 22, 1873. 

 Dear Sir: I looked, over some salinon-stomaclis last November. I 

 told Mr. Smith the result, and supposed that he put this item in with 

 his report to yoii. I learned the other daj- from him that this was not 

 the case. 



The fact was, that there was no regnlaritj' in the number or arrange- 

 ment of the ctecal appendages. They ran all the way from 44 to 70, 

 gradually, continuously, and without grouping. 

 Very respectfully, 



JAMES K. THACHER. 

 Professor S. F. Baird. 



2. — ON THE CONTENTS OF THE STOMACH. 



New Haven, November 11, 1872. 



Dear Sir : I have carefully examined the salmon-stomachs, sent on a 

 few days ago, but find nothing in them which could have served as food. 

 The stomachs themselves were entirely empty, except one, which con- 

 tained a single specimen of the external, Caligus-like, parasite, sent by 

 Mr. Atkins as from the salmon. This may have been accidental. The 

 intestines usually contained, especially in the pyloric region, consider- 

 able mucus, which revealed nothing under the microscope. In several 

 specimens, the intestines contained a few fish-scales, which, I presume, 

 are those of the salmon, as they were also frequently found upon the 

 outside of intestines, and loose in the i^ackages. 



In one specimen, there were two small bits of wood in the intestine 

 These specimens, with a few intestinal worms, which were found, I have 

 preserved to return with the stomachs as soon as you wish. 

 Very truly, yours, 



SIDNEY I. SMITH.

[According to Dr. A. C. Hamlin, the examination of many hundred 

 salmon in the Bangor market revealed no kind of food, exceptiug in a 

 single instance, where two small fishes were discovered. — S. F. B.J
