defcription of a new fpecies of Monkey, 
which he names fince Symia Entellus. The 
body of this animal, which is a native of 
Bengal, is of a pale ftraw colour, and in 
form and fize bears a ftrong refemblance 
to the Sima Nemeus, It meafures in 
-length about three feet, the tail is con- 
fiderably longer than the whole body, 
and terminates ma buth of long hairs, 
of a paler hue than the other parts of the 
animal. “Phe hands and feet are black, 
and the callofities on the pofteriors un- 
commonly large. 
TheAbbé BERTINELLI, in his ¢* Die 
courje concerning the prefent State of Luiera- 
ture and the Arts,in Mantua, intorms us, 
on the authority of a manuicript by one 
Tobn Piccinardi, preferved in the library 
of Cremona, that it was cuftomary in the 
asth century, on the feftival of St. Paul, 
to chaunt a hymn in honour of the poet 
Virgil. According to an ancient tra- 
dition, the apofile of the Gentiles is faid, 
on his arrival at Naples, to have paid a 
vifit to Virgil’s tomb, and to have ex- 
prefled his regret, in lively terms, at not 
having been a cotemporary of the Man- 
tuan bard, that he might have enjoyed 
anopportunity of forming a perfonal ac- 
quaintance with this excellent poet, and 
converting kim to the Chriftian reli- 
gien. This tradition is related in the 
following lines, which conftitute a part 
of the hymn formerly chaunted in honour 
of Virgil, on the feftival of St. Paul: 
Ad Maronis maufoleum 
Duttus, fudit fuper eum 
Piae torrem lacrymae. 
Quem te, inquit, reddidiffem, 
Si te vivum inveniflem, 
Poetarum maxime.

The 7zf number of the ** Axnales de

rived in this country. It is one of the 
moft important of the whole feries, as will 
appear from the following extraéts :

GREN, on the formation of fulphate of 
foda (glauber’s falt)_in fea water and 
brine {prings, by expofure to a tempera- 
tare below the freezing point; and an 
‘eafy method of freezing it from the deli- 
quefcent falt.”” The fubject of this memoir

manufaéturer of falt. . The chief fagis 
contained in it.are the following: ... 
I. Sulphate of magnefia (Epfom falt) 
and muriate of i¢da (common jalt) being 
added to each other in folution, and dfub- 
jected to congelation, are reciprocally de-. 
compofed into fulphate ef foda and muri- 
ate of magnefia, nor will the two newly 
formed neutral falts be decompofed by 
reftoring the former temperature of the 
mixture; by the fimple proceis, therefore, 
of freezing fea water, any quantity of 
giauber’s falt may be readily procured. 
Ti. The. deliquefcent falts contamed 
in fea-water, or brine fprings, which form 
the mother-water and contaminate the 
falt,. are muriate of lime, or -muriate of 
magnefia, or both together. mS raat 
1. When the muriate of lye is the 
only contaminating matter, an addition 
of fulphate of foda (glauber’s falt) pro- 
cured in the manner above-mentioned, 
will decompofe the muriate of lime, form- 
ing muriate of feda (common fait) an 
fuiphate of lime, which bemg an infolu- 
ble falt, will be precipitated, and from 
which the liquor may ealily be poured off 
clear. ais 
2. If the water contains muriate of mag 
nefia, quick lime isto be added, which 
forms muriate of lime, wnile the magnefia 
is precipitated ; the muriate of lime is af- 
erwards to be decompofed by the frft 
proce(s. 
3. Ifmuriate of lime and muriate of 
magnefia exift together in the fait liquor, 
the muriate of lime is firft to be got rid 
of by procefs 1. and muriate of magnefia 
by procefs 2. 
The advantages to be derived from 
thefe proceffes are yery important :. in the 
firfi place, the quantity of the falt is in- 
creafed, and the evaporation may fafely 
be carried on to drynefs, as no motlfer 
water will remain. Secondly, the quality 
of the falt will be greatly improved, and 
it will net be at all fubject to deliquefce, 
or become moift by expofure to the air, 
Thirdly, a confiderable quantity of mag-. 
nefia is procured,
