fpecies of bat is in all refpeéts analogous 
to the roufette: —it refembles it in the 
form of the molar teeth, in haying a 
nail on the fecond digit of the fore 
paws, in the fhortnefs of the tail, &c, 3 
but it feemed, however, excluded trom 
that genus on account of the incifores, 
which Pallas found to the number of 
two in the upper jaw: thefe teeth, which 
were altogether wanting in the lower jaw, 
had been broken out; an accident pretty 
frequent with bats. This has been ai- 
certained, by finaing in the cephalotte 
that has arrived at the Mufeum, four in- 
cifores in each jaw, asin the whole tribe 
of roufettes. This ob/eryation leaves no 
longer any room for doubt with refpeé ro 
the general determination of the ve/pertilio 
cephatates, ~— 2. The Weazel of Java, 
Seba is the only author that has made 
mention -of this fpecies, and who has 
given a figure of it in his forty-eighth 
plate. Syltematic authors had not ven- 
tured to confider it as a diftin® fpecies. 
It bears the ftrofigett analogy toa ferret, 
but deviates from it in its {kia, or colour of 
a fallow brown, and by yellow fpots 
above the eyes. —3. A Tatow with ten 
hands. This is only a variety of the 
cachicame, or of the tatou with nine 
bands. —4. A Hedge-hog of Malacca. 
The one juft received at the Mufeum, is 
probably one of the young individuals de- 
figned or figured by Seba; it has a clofer 
affinity to the hedge-bogs of Europe, than 
to thofe of Madagafcar.—5. A new fpe- 
cies of fhrew-moule (forex alba). Tie 
figure of this Shrew-moufe is found in the 
Thefaurus of Seba, plate 33, fig. 7.; but 
as it is there given under the name of 
American Rat, it has been neglected,-and 
does not oceur in any fyftematic work. 
Its teeth refemble, in number and form, 
that of our European fhrew-movfe; it is 
three times greater, and all whise; its 
tail is covered with long hairs, rare and 
verticiliated, or curled upward. Although 
prélerved in liquor, it yields a very ftrong 
icentof mufk. Seba obferves, that it feeds 
chiefly upon nuts. 
Lately at Paris, in the School of Na-

cide on the uleful purpofes to which this 
novel invention may be applied. In the 
interim, the boat is open every day to the 
inf{pection of all comers at the manufac- 
tory, in the Rue Notre Dame des Champs, 
at Paris, Fauxbourg St. Germain. 
An experiment has lately been made at 
Lyons to try the effects of vaccination in. 
prelerving fine-woolled fheep from the ra- 
yages of the fcab, which prevailed in the 
neighbourhood, and haa already extended 
its pernicious influence to a flock of come 
mon fheep, belonging to M, Furanpres 
D’Espinay. Another flock of the Merinos 
breed, belonging to the fame gentleman, 
was fubmitted to vaccination, which pro- 
duced its ufual effect, and preferved the 
flock in the midft of the contagion. Forty 
of the fheep which had undergone the 
operation were placed among the infected 
flock, but they withftcod the attacks of 
the difeale, while not one of thofe which 
had not be-n vaccinated efcaped.

M. De La Haye difcovered, during 
his travels, a {pecics of wheat, a fingie 
grain of which produces a trunk wita 
trom tweive to eighteen fhoots. Each 
fhoot has a bunch compofed of ten or 
twelve grains. This dilcovery has been 
announced to the Minifter of the Interior 
in France, and from it much advantage 
is expected. . 
Baron .D’Arerin, librarian to the 
Elector of Bavaria, has dilcovered an old
