protuberans on both sides of slides and beaker. There were also spores
and mycelial filaments of fungi, dirt, and zoospores. The drops of dew
were collected with capillary tubes such as were used in Edinburgh for
vaccine virus. The fluid was then preserved and examined in the naval
laboratory. In a few hours the spores disappeared.

Observation 32. Some of the earth near the site of the exposure referred
to in Observation 31, was examined and found to contain abundantly the
Gemiasma verdans, rubra, Protuberans lamella, confirmed by three more
observations.

Observation 33. In company with Surgeon F. M. Dearborne, U.S.N., in
charge of Naval Hospital, the same day later explored the wall about
marsh west of hospital. Found the area abundantly supplied with
palmellae, Gemiasma rubra, verdans, and Protuberans lamella, even where
there was no incrustation or green mould. Made very many examinations,
always finding the plants and spores, giving up only when both of us
were overcome with the heat.

Observation 34. August, 1881. Visited the Wallabout; found it filled up
with earth. August 17. Visited the Flushing district; examined for the
gemiasma the same localities above named, but found only a few dried up
plants and plenty of spores. With sticks dug up the earth in various
places near by. Early in September revisited the same, but found nothing
more; the incrustation, not even so much as before. The weather was
continuously for a long time very dry, so much so that vegetables and
milk were scarce.

The grass and grounds were all dried up and cracked with fissures.
