The small proportion of cases giving a history of having eaten 
uncooked shellfish shows that shellfish this ^^ar, as was the case in 
1906, could not have been the means of transmitting the infection to 
any considerable number of cases. 
All but 9 of the 523 cases occurred between May 1 and Xovember 1, 
during which period comparatively few raw oysters or clams are 
eaten in the District of Columbia. 
OCCUPATION. 
In the following table is given the occupation of the cases, along 
with the number of persons in the District of Columbia, according
