If now one increased artificially in the vicinity of the bacillus the
amount of necrotizing substance in the tissue, the necrosis would
spread a greater distance. The conditions of nourishment for the
bacillus would thereby become more unfavorable than usual.

In the first place the tissue which had become necrotic over a large
extent would decay and detach itself, and where such were possible
would carry off the inclosed bacilli and eject them outwardly, so far
disturbing their vegetation that they would much more speedily be
killed than under ordinary circumstances.

It is just in looking at such changes that the effect of the remedy
appears to consist. It contains a certain quantity of necrotizing
substance, a correspondingly large dose of which injures certain
tissue elements even in a healthy person, and perhaps the white blood
corpuscles or adjacent cells, thereby producing fever and a
complication of symptoms, whereas with tuberculous patients a much
smaller quantity suffices to induce at certain places, namely, where
tubercle bacilli are vegetating and have already impregnated the
adjacent region with the same necrotizing matter, more or less
extensive necrosis of the cells, with the phenomena in the whole
organism which result from and are connected with it.

For the present, at least, it is impossible to explain the specific
influence which the remedy, in accurately defined doses, exercises
upon tuberculous tissue, and the possibility of increasing the doses
with such remarkable rapidity, and the remedial effects which have
unquestionably been produced under not too favorable circumstances.

Of the consumptive patients whom he described as temporarily cured,
two have been returned to the Moabit Hospital for further observation.

No bacilli have appeared in their sputum for the past three months,
and their phthisical symptoms have gradually and completely
disappeared.

CAN WE SEPARATE ANIMALS FROM PLANTS?

By ANDREW WILSON.

One of the plainest points connected with the study of living things
is the power we apparently possess of separating animals from plants.
So self-evident appears this power that the popular notion scoffs at
the idea of science modestly disclaiming its ability to separate the
one group of living beings from the other. Is there any danger of
confusing a bird with the tree amid the foliage of which it builds its
nest, or of mista
