SEA-FISHERIES LABORATORY. 343 



The results of these primary inoculations are shown 

 on the following table. It will be seen that the " enteri- 

 tidis reaction " was typical in each of the 12 anaerobic 

 cultures made. The colonies which resembled those 

 produced by Bacillus coli were counted, and the numbers 

 present in x 1 ^ cc. of the stomach juices of each shellfish 

 vary from 14 downwards. On two of the plates no 

 '* colon-like " colonies were present. In some of the 

 countings the number is to be regarded as a minimum 

 one on account of the fusion of colonies.
