outline drawings also, for the purposes of more perfectly completing his
drawings. I gave him some of the Gemiasmas between a slide and cover,
and also some of the earth containing the soil. He carried them home. It
so happened that a brother physician came to his house while he was at
work upon the drawings. My artist showed his friend the plants I had
collected, then the plants he collected himself from the earth, and then
he called his daughter, a young lady, and took a drop of blood from
her finger. The first specimen contained several of the Gemiasmas. The
demonstration, coming after the previous demonstrations, carried a
conviction that it otherwise would not have had.


AGUE PLANTS IN THE URINE.

I have found them in the urine of persons suffering or having suffered
from intermittent fever.

When I was at the Naval Hospital in Brooklyn one of the accomplished
assistant surgeons, after I had showed him some plants in the urine,
said he had often encountered them in the urine of ague cases, but did
not know their significance. I might multiply evidence, but think it
unnecessary. I am not certain that my testimony will convince any one
save myself, but I know that I had rather have my present definite,
positive belief based on this evidence, than to be floundering on doubts
and uncertainties. There is no doubt that the profession believe that
intermittents have a cause; but this belief has a vagueness which cannot
be represented by drawings or photograph. Since I have photographed the
Gemiasma, and studied their biology, I feel like holding on to your
dicta until upset by something more than words.
