and I kept them for several years and demonstrated them as I had
opportunity. You also showed me on this visit the following experiments
that I regarded as crucial:

1st. I saw you scrape from the skin of an ague patient sweat and
epithelium with the spores and the full grown plants of the Gemiasma
verdans.

2d. I saw you take the sputa of a ague patient and demonstrate the
spores and sporangia of the Gemiasma verdans.

3d. I saw you take the urine of a female patient suffering from ague
(though from motives of delicacy I did not see the urine voided--still I
believe that she did pass the urine, as I did not think it necessary to
insult the patient), and you demonstrated to me beautiful specimens of
Gemiasma rubra. You said it was not common to find the full development
in the urine of such cases, but only in the urine of the old severe
cases. This was a mild case.

4th. I saw you take the blood from the forearm of an ague patient, and
under the microscope I saw you demonstrate the gemiasma, white and
bleached in the blood. You said that the coloring matter did not develop
in the blood, that it was a difficult task to demonstrate the plants in
the blood, that it required usually a long and careful search of hours
sometimes, and at other times the plants would be obtained at once.

When I had fully comprehended the significance of the experiments I was
filled with joy, and like the converts in apostolic times I desired to
go about and promulgate the news to the profession. I did so in many
places, notably in New York city, where I satisfactorily demonstrated
