From a comparifon of tite zbove with 
the obfervations inferted in the Monthly 
Magazine for Jan. 1797, it appears, that, 
notwithitanding a great variation in parti- 
eular months, the average of the wicle year 
4797 differs but £° from that of 17965 
which was 522. The months, January, 
April, June, Auguit, September, veere 
colder in 1797 than in the year preceding; 
the other months were hotter in a greater 
or lefs degree. July 17th, 1797, was 6° 
higher than July rsth, 1796, but the 
thermometer never funk fo low as in fome 
ef the days preceding the Chriftimas of

For the Monthly Magazine. 
R.RENNELL having feen in the 
Monthly Magazine, a public men- 
‘tion of a report of his being concerned in 
the Purfuits of Literature, is perteCtly con- 
winced that the Editers will have the juf- 
tice to contradict, from him, in the moft 
diftin& pointed manner, fo groundle{s and 
injurious a report. In no part of that 
production had Dr. Renneli the moft 
diftant co-operation. Satirical writing of 
svery kind, particularly of an azonymous 
#ature, is perfectly alien to his habits and 
eccupations. 
Dr. RENNELL will confider the infer- 
‘tion of this declaration in their next Ma- 
gazine as a confiderable obligation ¢on~ 
¥erred upon him by the Editors. 
‘London, Dete 35) 1797 
To the Editor of the Monthly Magnzine. 
SIR, 
ee is well known fhat many medicaf 
men have been lately engaged in mak- 
ing experiments to afeertain whether, or 
not, the vexereul difeafe, in all its com-~ 
plicated forms, can be radically cured by 
medicines containing a large proportion 
of oxygen, or vital air; and particularly 
by means of the nitrous acid and oxy- 
genated mufiate of pot-afh. 
The very refpeCtable teftimonies which 
have already appeared in ‘favowr of thefe 
remedies, and the mild as well as expedi - 
tious manner in which they are faid te 
operate, ha¥e induced me to give them @ 
fair and unprejudiced trial, in a great 
variety of cafes; and alfo to folicit the 
communications of other gentlemen in 
London, whe have had opportunities of 
exhibiting them: but 1 am forry to ob- 
ferve, that our experienee obliges me to 
differ in opiniow from thofe phyficians 
and furgeons who have raifed our ex- 
pectations on this fubjeét. | 
This diverfity of opinion being found- 
ed on actual obfervation, and not on any 
preconceived notions, has emboldened me 
to ufe the freedom of circulating a printed 
letter, to recommend the trial of the new 
medicines in advanced ftages of the dif- 
eafe; where well marked blotches, nodes, 
ulcerated fouces, ozena, and other cha- 
racterifiic fymploms of a genuine fypbiles 
appear: fince, in thefe cafes only can we 
be fully affured that the fyphilitic poifow 
exifts in the conftitution, and iadubitably 
requires the adminiftration of an anti-ve- 
nereal medicine. 
The moit judicious praftitioners, and 
thof of the largeft experience, are ready 
to contefs, that although it be ufually ad- 
vifeable to give mercury in recent ftages 
of the venereal difeafe, with a view to 
prevent the farther progrefs of the fymp- 
toms, or the oecurrenee of a confirmed 
lues venerea, yet, in very many fuch in- 
fgances, the patients would efeape and re-- 
cover their health, by a proper plan of 
treatment, without the ule of mercury: 
and, notwithftanding this faét may be 
denied by fome fpeeulative perfons, it is 
too well authenticated for us to reft the 
proof of an anti-venereal remedy /olely, or 
ever chiefly, on its efficacy to remove the 
primary {ymptoms. All deductions from 
fuch premifes muft, therefore, be extremely 
fallacious and queftionable. 
I have taken the liberty to trouble you 
with thefe curfory hints, for the attention 
of medical men in the country, in hopes 
that you will favgur me by inferting them
