But they had no well marked double outline. There were no
forms found in the urine of this patient. In another case (Donovan,) who
six months previous had had Panama fever, and had well nigh recovered, I
found no spores or sporangia.
Observations made at Washington, D.C., Sept., 1879. At this time I
examined with clinical microscope the blood of eight to ten persons
living near the Congressional Cemetery and in the Arsenal grounds. I was
successful in finding the plants in the blood of five or more persons
who were or had been suffering from the intermittent fever.
In 1877, at the Naval Hospital, Chelsea, I accidentally came across
three well marked and well defined Gemiasmas in the blood of a marine
whom I was studying for another disease. I learned that he had had
intermittent fever not long before.
Another positive case came to my notice in connection with micrographic
work the past summer. The artist was a physician residing in one of the
suburban cities of New York. I had demonstrated to him Gemiasma verdans,
showed how to collect them from the soil in my boxes. And he had made
outline drawings also, for the purposes of more perfectly completing his
drawings.
