whom my own acknowledgments and those of the Sanitary Committee
are due, I have now a pretty correct list of all the cases that have
occurred in connection with it. The cases amount to about 160, and
although, in the houses where the first cases that came to my knowledge
occurred, there were some flagrant sanitary defects which were calculated
to promote the occurrence of fever, I am satisfied that in other
instances, and probably the major part of them, the invasion of fever
was due to a cause with which this class of defects had little or nothing
to do. My inquiries into the cause of the extension of the fever have
therefore been pursued in quite a different direction. They are not
yet completed, but so far as they have gone, they point to nothing
which requires any further action than that which has been already
taken. Both the cause and the effect have ceased to exist.
