treatment more or less speedily, to recur, however, in
some cases, under conditions similar to those under
which it first appeared. The presence of both sugar
and albumin in the urine indicates serious disturbance
in the metabolic processes, calling for relief to the
nervous strain which the patient may have been under-
going, and an adjustment as far as can be of his en-
vironment, but under favorable conditions these pa-
tients may continue in at least fair average health for
4. Chemiotaxis, — Barratt summarizes his observa-
tions on chemiotaxis as follows: I. Paramcecia pass
readily into tubes containing acid and alkaline solu-
tions of sublethal concentration, but pass still more
readily into control tubes containing the same liquid
as that in which the paramcecia are immersed. 2. Only
negative chemiotaxis appears to be exerted by acids
and alkalies upon paramcecia. This negative chemio-
taxis is marked in alkaline solutions of lethal concen-
tration, and is slighter in acid solutions of lethal con-
centration. 3. There is no parallelism between (a) the
lethal concentration of acids and alkalies for para-
mcecia, and (b) the chemiotaxis of paramcecia in re-
spect of acids and alkalies. 4. The taxis of paramcecia
is modified when these organisms are transferred from
ha}' infusion to distilled water. 5. Chemiotaxis is not
to be explained simply by reference to the acidity or
alkalinity of the solutions employed. Mere change of
concentration is an important factor in its production.
6. Negative chemiotaxis does not necessarily indicate
that the liquid tested acts injuriously upon the organ-
6. Lead Poisoning from Electrolysis. — Roberts re-
ports a case of lead poisoning, caused by water used
for drinking purposes, it containing 0.14 grains of lead
to the gallon. On investigation it was found that the
water was supplied through a lead pipe, the interior
of which showed patches of lead carbonate, due to
electrolysis. The lead pipe was crossed by an electric
cable passing about eighteen inches above it. At this
point in the cable there was a leak of 1.8 volts, suffi-
cient to cause the electrolysis.
7. Trypsin and Cancer. — Beard's experiments were
undertaken to determine the action of trypsin upon the
living cells of a carcinoma. To this end mice suffer-
ing from Jensen's mouse tumor were injected with
suitable amounts of trypsin. On killing the mice every
single tumor cell was found to be in degeneration. The
somatic tissues (leucocytes and connective tissue stroma
cells) were quite normal. It appears to be certain that
the action of trypsin upon the cancer cell is to pull
down the cancer albumin — a living substance — and the
cancer ferment (malignin) produced by this. In ad-
dition to their confirmation of the conclusion that tryp-
sin is the substance which will destroy the cancer cell
with ease and without danger to the individual, these
experiments go far to prove that in its nature cancer
is neither germinal nor somatic, for trypsin, the archi-
tect of the soma, does not in life destroy the soma or
sexual individual or its sexual products, whilst its ac-
tion is direct and utterly ruinous upon trophoblast or
