Since the printing of the third edition 
of Mr. ForsytTu’s Book on Trees, he has 
been vifited by the following gentlemen, 
and been favoured with their concurrent 
teftimony'as beneath : 
°* To Mr. For{yth, Royal Gardens, Kenfington. 
** Sir, As you had the goodnefs lately to 
give us an opportunity of examining feveral 
trees in Kenfington Gardens, in the various 
ftages of renovation, or filling up with new 
wood ; and as reports have been circulated, 
tending to difcredit the efficacy of your pro- 
cefs; We feel it an act of juftice, not only to 
you, but to the country, which is deeply in- 
terefted in your difcoveries, thus publicly to 
declare, that the ftatements you have pub- 
lithed on the fubje& contain nothing more 
than the Truth.—John Coakley Lettfom, 
William Woodville, James Sims, William 
Norris, jofeph Hart Myers, Aftley Cooper, 
Edward Coleman, H, N.. Willis.” 
London,. Nov. 17; 1303. 
Mr. Forsyru has alfo announced a 
difcovery recently made; and which, as 
calculated to faye time and labour, de- 
ferves attention, Inftead of paring away 
the bark, as had heretofore been the prac- 
tice, and covering the ftem with the com- 
pofition, he now merely fcrapes off the 
Joofe bark, and applies a mixture of cow- 
dung and urine only (made to the confif- 
tence of thick paint), with a painter’s 
brufh ; covering the ftem carefully over. 
This foftens the old {cabrous bark, which 
peels off during the following winter and 
{pring, and is fucceded by a fine {mooth 
new bark.

Dr. De Carro, of Vienna, has ad- 
dreffed a Letter to Dr. Jenner containing 
the following extraordinary circumftances, 
tending to prove that the Vacciolous Ings 
culation is a preventative of the Plague: 
‘* Your difcovery has produced fome con- 
fequences which you furely were very far 
from forefeeing, when you made it known to 
the world. I believe that £ once mentioned 
to you, that a French phyfician, Monf. La- 
font, thought he had obferved, that vaccinat- 
ed people were not attacked by the plague. 
He defcribed to me the fa&ts which raifed the 
fufpicion; they were few, and not very con» 
clufive ; bus he fpoke of his new obfervations 
with modefty and prudence, and thought only 
that the fubject deferved his further atten- 
tion. Another phyfician at Conftantinople, 
Monf. Auban, who never had any commuani- 
cation with M. Lafont, who is of Salonica, 
wrote to me about a year ago, that he alfo 
had fome fufpicion of the Cow-pox being a 
prefervative againft the plague—did not men~ 
tion faéts, but faid that feveral people had 
obferved the fame, and many vaccinated 
themfelves as a fecurity againft the plague. 
Guefs what was my aftonifhment when, a 
few days.ago, Ireceived, through the French 
ambaflador at Vienna, a packet of Dr. Au- 
ban, who begins his letter with thefe words + 
** What I had the honour of mentioning to 
you long ago, concerning the Cow-pox being 
a fecurity againft the plague, as a probability, 
I can now, after many experiments, {peak of 
almoft as a certainty.” He defcribes the fa&ts 
fummarily in his letter, and adds two proces 
verbaux, figned by him and feveral witnefles, 
defiring Citizen Champagny and myfelf to
