In a preceding note upon the same subject, Mr. Hospitalier remarked
that upon combining these effects of perspective with those of the
praxinoscope, which give the sensation of motion, we would obtain
entirely new effects. It would be perhaps complicated as to the
installation, and especially as to the making of the images, but, in
certain special cases (for giving the effect of a machine in motion,
for example), it might render genuine services.--_La Nature_.

THE EFFECT ON FOWLS OF NITROGENOUS AND CARBONACEOUS RATIONS.[1]
[Footnote 1: This article is condensed by permission from a thesis
prepared for the degree of Bachelor of Science in Agriculture, by
James Edward Rice, a graduate of the class of 1890. The work was
planned and wholly carried out in the most careful manner by Mr. Rice
under the immediate supervision of the Director. The results have been
thought worthy of publication in the _Cornell Station Bulletin_.]
On July 2, 1889, ten Plymouth Rock hens, one year old, and as nearly
as possible of uniform size, were selected from a flock of
thirty-five. At the same time ten chickens, hatched from the same hens
mated with a Plymouth Rock cock, were similarly chosen. The chickens
were about six weeks old, healthy and vigorous and of nearly the same
size. Up to the time of purchase both hens and chickens had full run
of the farm. The hens foraged for themselves and were given no food;
the chickens had been fed corn meal dough, sour milk and table scraps.
