valuable, to communicate it, and so long as he observes the rules of
good society the profession are to give him a respectful hearing,
even though he may have made a mistake. I do not think you had a fair
hearing, and hence so far as I myself am concerned I indorse your
position, and shall do so till some one comes along and gives a better
demonstration. Allow me also to proceed with more evidence.

Observation at West Falmouth, Mass., Sept 1, 1877. I made five
observations in like manner about the marshes and bogs of this town,
which is, as it were, situated on the tendo achillis of Cape Cod, Mass.
In only one of these observations did I find any palmellae like the ague
plants, and they were not characteristic.

Chelsea, Mass., near the Naval Hospital, September 5, 1877. Three sets
of observations. In all spores were found and some sporangia, but
they were not the genuine plants as far as I could judge. They were
Protococcaceae. It is not necessary to add that there are no cases of
intermittent fever regarded as originating on the localities named.
Still, the ancient history of New England contains some accounts of ague
occurring there, but they are not regarded as entirely authentic.

Observation. Lexington, Mass, September 6, 1877. Observation made in
a meadow. There was no saline incrustation, and no palmellae found. No
local malaria.

Observation. Cambridge, Mass. Water works on the shore of Fresh Pond.
Found a few palmellae analogous to, but not the ague palmellae.

Observation. Woburn, Mass, September 27, 1877, with Dr. J. M. Moore.
Found some palmellae, but scanty. Abundance of spores of cryptogams.
