SUBSTITUTE FOR CINCHONA, 
C. Zannetini, a phyfician who attended the French army 
in Italy, has madé fome experiments, by which it appears 
that the flowers and feeds of the common nettle (Urtica di- 
oides Ltn.) may be employed in fever inftead of cinchona. 
This fubftitute was attended with a fuccefs beyond all ex- 
pectation, in tertian and quartan malignant fevers. The 
nettle often produces a fpeedier effeét than bark, for it heats 
in a gréat degree, and, when the dofe is pretty ftrong, occa- 
fions a lethargic fleep. The dofe muft never exceed a dram, 
and is given in wine two or three times in the courfe of 
24 hours. Zannetini found this medicine of great fervice to 
guard againft that total exhauftion which forms the principal 
character of malignant fevers; and he recommends a flight 
infufion of it in wine as an excellent prefervative for thofe who 
refide in marfhy and infalubrious diftrias. In employing 
the nettle in fever, Zannetini gives the fame caution as ought 
to be abferved in regard to cinchona, that is, that it muft not 
be employed where there is an inclination to inflammation, 
or where a continued fever, arifing from obftructions, exifts. 
This difcovery is not unworthy the attention of phyficians, 
and deferves at Jeaft to be farther inveftigated, as a great deal 
would be faved if cinchona could be entirely difpenfed with. 
CURE FOR DISEASED ELMS. 
C. Boucher, fecretary to the Society of Emulation at Ab- 
beyille, has lately publifhed a memoir on the difeafes which 
attack elms, and the method of curing them, from which 
the following is an extract :—‘ Elms are frequently attacked 
by ulcers, which at length deftroy a great number of thefe 
valuable trees. Duhamel fuppofed that this malady might 
_ be afcribed to a plethora of the fap; and C. Boucher, by 
numerous experiments, has eftablithed this fa&t, and difco- 
yered aremedy. He obferved, that local ulcers never attack 
the tree on the north fide, but almoft always on that expofed 
to the fouth. The elms chiefly fubje& to it are thofe planted 
in marthy ground, and in the neighbourhood of rivers. The 
ulcer is generally at a little diflance from the earth, feldom
