DUNHAM S SOLUTION WITH VARIOUS PROPORTIONS OF SODIUM CHLORID. 



Table XXVII, gives the results of three experiments, showing that 

 the growth of cultures 1 to 6 and Bacillus coli is good only in those 

 solutions containing 3 per cent or less of sodium chlorid. There was 

 growth in the 7 per cent solution, but it was very slight. The 

 amount of indol produced by the organism as shown in the column 

 for 25 days indicates to some extent the amount of growth in each
