of August, when they in ague localities spring into existence in vast
multitudes, and continue to develop in great profusion till frost comes.

Dr. Cutter writes me September 28, 1882: "My dear Professor: By this
mail I send you a specimen of the Gemiasma rubra of Salisbury, described
in 1862, as found in bogs, mud holes, and marshes of ague districts, in
the air suspended at night, in the sputa, blood, and urine, and on
the skin of persons suffering with ague. It is regarded as one of the
Palmellaceae. This rubra is found in the more malignant and fatal types
of the disease. I have found it in all the habitats described by Dr.
Salisbury. Both he and myself would like you to examine and hear what
you have to say about it."
