The Springfield epidemic of August, 1892, was likewise attributed to the milk as a source of infection. Other cases are also here recorded.

A careful investigation of the well water, spring and deep well water supplying the college was made by Dr. HarrimanT who had charge of the college hospital, and therefore had a good opportunity for studying all the conditions. He concluded that the milk supplying the college dining room was the source of infection. The general conclusions reached by the writer in a paperf were as follows: It may be stated that so far as the analyses show the college water supply may be considered excellent. It is true that in a number of instances more organisms were found than at other times, but an examination made from time to time shows that the number is not unusually large, and on the whole that we may consider our water supply piactically pure, and I should also state that the water from the spring supply is unusually good. We should bear in mind that the failure to find the typhoid fever bacillus in the water supply of the Briley well is not at all surprising.
