In regard to other circumstances relative to the presence of this
fungus, there are, above all, two remarkable facts, namely, its property
of adhering to surfaces as perfectly polished as that of a mirror, and
its power of resistance against the reagents, if we except the caustic
alkalies and the concentrated mineral acids. This power of resisting the
ordinary reagents explains in a plausible manner why the fungus is not
destroyed by the digestive process in the stomach, where, however, the
acid reaction of the gastric juice probably arrests its development--is
that of the schistomycetes in general--and keeps it in a state of
temporary inactivity. This property of adhering to smooth surfaces
explains perhaps the power of the Eucalyptus globulus in arresting the
progress of paludal miasm (?). But it is evident that other trees,
shrubs, and plants of resinous or balsamic foliage, as, for example, the
Populus balsamifera, Cannabis sativa, Pinus silvestris, Pinus abies,
Juniperus communis, have equally, with us, the same faculty; they are
favorable also for the drying of the soil, and the more completely, as
their roots are spreading, more extended, and more ramified.

In order to demonstrate the presence of the limnophysalis in the blood
of patients affected with intermittent fever during the febrile stage,
properly speaking, it appeared necessary for me to dilute the blood of
patients with a solution of nitrate of potassa, having at 37.5 deg.C. the
same specific gravity as the serum of the blood. With capillary tubes of
glass, a little dilated toward the middle, of the same shape and size as
those which are used in collecting vaccine lymph, I took up a little
of the solution of nitrate of potassa above indicated. After this I
introduced the point of an ordinary inoculating needle under the skin,
especially in the splenic region, where I ruptured some of the smallest
blood-vessels of the subcutaneous cellular tissue. I collected some
