September, 1908. These cases need only to be seen at the bedside or 

 at autopsy to recognize the possibility that they may be cases of cholera 

 in which the vibrio has lost some of its properties, including its ag- 

 glutinability with high dilutions of anticholera serum. 



Kolle/ in a series of vibrios taken from cases in Egypt, which clinically were 

 cholera, found only a few vibrios which did not agglutinate with anticholera 

 serum. Kolle's conclusion was that these eases were cholera, but that the cholera 

 organism was not isolated because of faulty technique. His contention is 

 that other vibrios are sometimes found in the human intestine; these, in the 

 enriching fluid, grow more vigorously than the cholera vibrios, and .so the 

 investigator may easily fail to isolate the cholera organisms. This seems unlikely 

 to occur in any considerable nurfber of ca.ses, especially if the transfer to the 

 hard media is made directly from the stool, or after a very short time of 

 growth in the peptone solution. 



In September, from the 1st up to the 9th, there was an average of 

 about three cases daily. On the 10th the cases reached seven, on the 

 11th nine, and on the l"2th seventeen. The course of the disease is well
