subserving especial functions, cannot be maintained. Intelli- 
gence, sentiment, the passions, and the natural appetites, are 
not localised in portions of cortical substance capable of aCting 
separately. The limited destruction of any part whatsoever of 
the cortical substance is unable to paralyse the aCtion of a muscle 
in a permanent manner, or to withdraw it from the aCtion of the 
will. 
Herr J. Kuhn describes a half-breed, between a Gayal bull 
from Further India and a cow of the long-horned African race 
common in the Soudan. 
Mr. H. C. Hovey (“ American Naturalist”) records the case 
of a cat which had become completely blind from cataraCt, but 
which is still a capital mouser, and succeeds in finding its way- 
home from a distance, even when the ground is covered with 
snow. 
M. Timiriazeff, in a study on chlorophyll (“Comptes Rendus”), 
notes that the position of maximum energy, as fixed by Mr. 
Langley in the orange ray, corresponds precisely to the charac- 
teristic band of chlorophyll (between B and C). Chlorophyll 
seems able to convert into work 40 per cent of the energy 
absorbed. 
M. de Chardonnet (“Comptes Rendus ”) has studied the pene- 
tration of the solar radiations in the eye of man and of the verte- 
brate animals. He proposes the law that no medium of the eye 
in the vertebrates is transparent for waves shorter than T or U, 
the limits of the ultra-violet solar speCtrum. The vitreous body 
presents a mere trace of fluorescence in the sparrow-hawk ; the 
fluorescence of the cornea appears in the owl and the carp, the 
cat, and the sheep. The crystalline lens is generally fluorescent. 
Dr. J. Blake, in a communication to the Academy of Sciences, 
combats the view of M. Rabuteau, that the toxic power of metals 
is simply proportional to their atomic weight, and shows that 
this merely holds good in one and the same isomorphous group. 
Herr Ludwig (“ Botan. Central-Blatt ”) has shown that under 
certain circumstances Agaricus tuberosus is distinctly phos- 
phorescent. 
Herr Rohmann (“ Pfliiger’s Archiv. Phys.,” xxix., p. 509) has 
proved experimentally that so long as the nutriment is normal 
the intestinal canal can perform the functions necessary for the 
preservation of the organism, even in the absence of bile. The 
phenomena of putrefaction noticed by earlier observers occur 
only when the diet contains fat in abnormal quantities. 
M. Dareste (“ Comptes Rendus ”) confirms his former result 
that the longer the interval between the laying of an egg and the 
beginning of incubation the greater the probability of the
