CARRIAGE OF INFECTION IN BERMUDA 251 



reported by Cochrane (1912). This occurred at St George's, 

 Bermuda, and flies were considered to be the probable carriers. 

 There were eight cases of fever; three of these were in soldiers 

 and the five civilian cases were in three families. Two of the 

 three soldiers were employed in two of the families. A fatal case 

 of typhoid had occun-ed at a house 300 yards from the house 

 where the first case occurred in September of the previous year ; 

 three cases occurred in April and May. A dry earth latrine was 

 used where the fatal cases of typhoid occurred. A fly was caught 

 near this latrine. It was put into 5 c.c. of sterile salt solution for 

 a minute and cultures made. The fly was emulsified and other 

 cultures made. Bacillus typhosus was isolated from the washings. 

 The house and the latrine were cleaned and disinfected and no 

 further cases have occurred in the vicinity since.
