On Infeéis which cure the Tooth-ache: 83 
them over each other, by which means his fingers, for a 
whole year, though he daily wafhed his hands, were en- 
dowed with the property of curing the tooth-ache, by merely 
touching the affe¢ted tooth. The author of the letter affirms, 
that the following method will always afford relief. The 
infect defcribed by Roffi, in his Fauna Etrufca, under the 
name of carabus chryfocephalus, is to be held for fome mi- 
nutes between the thumb and the fore-finger, and the dif- 
eafed tooth and the gums are to be afterwards touched with 
that finger.. If the pain does not ceafe on the firft touching, 
the finger is to be well dried, and mutt be applied to the in- - 
fest again, and then to the tooth; and this is to be conti- 
nued alternately till the pain ceafes entirely. M. Cypriani 
afferts, that he cured every cafe of the tooth-ache, without 
-exception, by this method, within the fpace of eight or nine 
minutes. 
More infects poffefs the like property, and experiments 
made with the following were equally fuccefsful.. The cara- 
bus ferrugineus of Fabricius; the coccinella feptem punc- 
tata (the lady bird); the chry/omela populi, and the chry/o- 
mela fanguinolenta. It would appear that this property be- 
Jongs to various kinds of the coleopéera. 
The idea of thefe infets being endowed with the property 
of curing the tooth-ache is not confined to Italy; for 
Dr. Hirfch, dentift to the court of Weimar, afferts (Ver- 
kundiger, September 24, 1798,) that he employed them 
with the happiefi effect, except in fome cafes where his pa- 
tients were females. Dr. Hirfch fays, that he took that 
fmall infect, found commonly among corn, coccinella /eptem- 
punGata, and bruifed it between his fingers. He then rub- 
bed the fingers with which he had bruifed it, till they be- 
came warm at the points, and touched with them the un- 
found parts of the gums, as well as the difeafed tooth. Dr.. 
Hirfch adds, that he made the fame experiment a few days 
after, with equal fuceefs, though he had not bruifed a new 
infe& with his fingers, He p inp to think, though the
