on isolated fragments only. These Skel-
etons proved what had been only sur
missed before, that the skeleton of Ne
andcrthal, the lower jaw of Naulette,
and the crania of Cronstadt belong to
one and the same race. The simian
characters Of these parts Of the skele-
ton are well-known
Localization Of the sense of sea an
emones.-Herr Nagel as recently been
conducting some experiments at Naples,
having for their object the localiza-
ton of the various senses of sea anemo-
mes. The results of his researches have
shown that the sense of taste resides
in the tentacles; and that though the
tentacles were apparently unsusceptible
to pain when cut, yet when touched,
near them, they gave evidences of be-
ing most sensitive. They are, therefore,
the seat Of three senses, viz, of touch,
taste, and smell.
Habits of Brazilian roaches.-Cock-
reaches are so common in Brazilian
country houses, says Mr.. Herbert
Smith, in Insect Life, that nobody pays
much attention to them. They have
an unpleasant way of getting into pro-
shoes, and sometimes clothing. Where
wall paper is used they soon eat it off
in unsightly patches, no doubt seeking
the paste beneath. But at Corumba,
on the upper Paraguay, | came across
the cOckrOach in new role. In the
house where we were staying, there
were nearly a dozen children, and ev-
cry one of them had their eyelashes
more or less eaten off by cockroaches
"a large brown species, one of the
commoneSt kind throughout Brazil. The
eyelashes were bitten off irregularly,
in some places quite close to the lid.
Lake most Brazilians, these children
had very long, black eyelashes, and
their appearance thus defaced was odd
enough. The trouble was confined to
children, / suppose, because they are
heavy Sleepers and do not disturb the
insects at work. My wife and l some
faces at night, but thought nothing
more of the matter. The reaches also
bite off bits of the toe-nails. Brazili-
ans very properly encourage the large
house spiders because they tend to
rid the house of other insect pests.
Tannin receptacles of the legumin-
oSae.-Dr. p. Baccarini has made an
exhaustive examination Of the struc-
ture and distribution of the tannin re-
ceptacles in large number of legumin-
osae, belonging to all the three tribes,
PapiliOnaceae, Caesalpinieae, and MINI
Oseae. These special receptacles are
especially well developed in the Loteae,
Galegeae, Phaseoleae, and in some
Hedysareae; though the tannin is by
no means confined to these receptacles,
but may be distributed in other por-
tons of the tissue. In the Podalirieae,
Genisteae, Trifolieae, and in some Gale
geae they are altogether wanting.
When present, they may be either as
ISOLATED with the vascular bundles
parafaScicular) or Independent Of
them extra fascicular), and one only
or both of the systems may occur in
the same species. The archaic form is
probably that found in Ceratonia sill
qua and Cercis siliquastrum, where
the eXtra-faScicular system is localized
in the epiderm; in other species it oc-
ours in the hypoderm or in the cor

panied by an abundance Of an albumin

different astrological character. The
author does not assign to these protO-
plasmic threads any function in connec-
ton with the distribution of nutritive
substances.
A new preservative fluid for SlugS.-
After repeated trials to obtain a good
preservative fluid for slugs, 1 have
found the following to act so admir-
ably in preserving the color, etc., that
/ think it would be well to place it
on record, so that others may benefit
by it's use. Dissolve 10 grains of alum,
2 IL grains of common salt, 1 IL grains
of potassium nitrate, 2 grains of ar
senious acid and 2 grains Of mercuric
chloride in 5sounceS Of distilled water,
and filter. After well cleansing the
slugs from mucus, I place them in
tubes containing the above solution,
and well seal with a mixture Of five
parts of old gutta-percha and four Of
asphalt applied hot, and obtain the
best results.-J W. Williams, in Sci
ence Gossip.
Cause of the digestion of albumen
by the leaves of certain plants.-N.
Tischutkin published an article in 1889,
in the Berichte der Deutschen Botani
schen Gesellschaft, on the cause Of the
digestion of albumen by the leaves Of
Pinguicula vulgariS L., in which he en-
deavors to show that the process Of
digestion is the result of the action Of
bacteria. This is in opposition to the
theory of Darwin and other authors
that the digestion is analogous to the
digestion by means of pepsin in the
animal kingdom.
In an article in volume XII. Of Acta
Hort Petropolitani he further discuss
es the subject and draws the following
conclusions:
l. The disintegration of albuminous
compounds by the secretion of carniv-
Orous plants is due to the growth OF
micro organisms, principally bacteria.
2 NIicro-o organisms possessing the
power of dissolving albuminous COM
pounds always vegetate in the secre-
tons Of completely developed car
