In experiments on nerve-muscle preparation of the frog,
veratrine in concentrations of 1:1000 to 1:100,000 pro-
duced Isolated tetanie contractions which after 5-40
minutes (depending on the concentration) began to in-

tweet tetanus caused by ssratrine poisoning of the nerve
and the increase in its supernormal phase of excitability
also caused by veratrine.

Speetrophotometric arrangements used by others and those by
the authors using cells which could not be brought up close
to the back of the cuvette had shown that the gang or Sor-
et absorption band, normally found at 410 to 420t. in the
absorption spectrum of free hemoglobin and many derivatives,
is not to be found in that of whole blood or suspensions of
red corpuscles. A So photoelectric cell was attached by its
sensitive flat surface to the back of the plane parallel
quarts. euvette, and the image of the slit nas brought to a
sharp focus on the front face. By means of this apparatus
the band was observed with nearly the same intensity in the
absorption spectra of ahols blood and suspensions of sopazti
ated and washed red corpuscles before and after Taking.
Thus. the previously observed disappearance of this band is
due to an effect of the ocattering of the light by the sue?-
puaded red corpuscles.

In one series of experiments the isolated heart of a frog
was perfused by the Straub method (a caanula was inserted
through the aorta into the ventricle) The solutions of
ace.tylebeline acted 'n1y on the 'uncles of the ventricle.
In these experiments only the negative inotropic e:tfect,
no-,,t accompanied by slowing of the rhythm, was observed. In
another aeries of experiments, the cannula wa introduced
into the right auricle; the solution acted on all alemeata
of the heart. In this case negative i otropic and nega-
tive chronotropic effects were observed.

Frog nerve-muscle preparations were subjected by mans
of liquid nonpolarizable electrodes to the action of a
direct current of 0.02-0.1 me for 5-10 minutes. Acetyl-
choline was added to the emulsions to a concentration of
1;100,000. At the cathoda the activity of the cholines-
terase is decreased; at the anode it is increased. The
content of unlhydrolyzed acetylcholine is higher in the
cathode emulsion and lower in the anode emulsion than in
control emulsions. The changes in the activity of the
eholineeterass may be due to the shirt of ione.in hb
nerve.
