An open pi'ivy, whicli had been overlooked ui) to this time, was dis- 

 covered in the horse stable immediately adjoining the milk room. Flies 

 were in great abimdance, and it was admitted by a member of the family 

 that they were frequently foimd in the milk room. 



The milk continued to show coli until August Sth, when it cleared up 

 entirely. 



THE NATURE OF THE DISEASE. 



The disease showed a very rapid onset accompanied by pain, high tem- 

 perature, nausea and vomiting. Diarrhoea always followed. Secondary 

 cases were numerous, especially among children. 



THE SPREAD OF THE EPIDEMIC. 



Until about August 12th, all cases occurred along the susjiected milk 

 route. Over 60 per cent, of these milk users were infected. On that date 

 one of the neighbors of an infected household came down with the disease. 

 From then on the contagion spread from one family to another, probably 

 through contagion, vmtil nearly every home in the community had or had 

 had the disease. 



Nothing was done to investigate the causes, although the State Board 

 of Health was asked to look over the situation. 



It might be said, to eliminate as many probable causes as possible, that 

 the town of Dublin does not have a common water supply. Most of the 

 water comes from driven wells or from the lake. Dublin is a summer re- 

 sort and everything is done to keep the town in as sanitary a condition as 

 possible. 



CONCLUSION. 



The epidemiology of this outbreak has not been studied carcfuH\ 

 enough to permit us to draw any positive conclusions. I have tried to 

 show the relation of the epidemic to the milk infected with coli. The evi- 

 dences seem to incriminate the milk, although a positive diagnosis of a 

 milk-borne epidemic cannot be reached from the data at hand.
