Mr. Parx1nson, of Hoxton, whofe va- 
luable publications we have frequently 
had oceafion to notice, has announced a 
new and interefting work, under the title 
of Organic Remains of a former World,

neralized remains of the Antediluvian Ve- 
getables and Animals. 
The Secretary of the Vaccine Pock Inflitution, 
Broad-freet, Golden-Jquare, bas addreffed the 
following Letter to the Editor of the Monthly 
Magazine.—** The public mind being of late 
much difturbed in confequence of fucceflive 
reports during the whole of the laft year, 
and efpecially of late, by publications of 
cafes efteemed to be inftances of the Small- 
pox two or three years fubfequently to the 
Cow-pock; the Medical Eftablifhment of this 
Inftitution have thought it their duty, what- 
ever may be their own opinions, not to be 
ina€tive and filent. Accordingly I am di- 
rected to ftate, that in the laft fortnight a 
number of fubjeéts who had undergone vac- 
cination in the year 1800, (the firf? year of the 
new practice at any profeffed inflitution) have 
been fubmitted to the teft or counter-proof 
wariolation, in circumftances the moft favour- 
“able for exciting the Small-pox. Befides 
thefe trials, additional ones have been infti- 
tuted on fubjeéts who were vaccinated in Dr. 
Pearfons and Mr. Keate’s early praétice in 
1799. Further: reports have’ been already 
received at the Inftitution from feveral pro- 
vincial correfpondents, who were witnefies 
to whole parifhes of fubjeéts vaccinated under 
Dr. Peaifon’s infpe€tion, or with matter fur- 
nithed by himfelf early in the year 1799.* A 
_ * It may be very important information to 
affirm, that the matter now ufed at this Infti- 
tution was that originally taken, in January 
and February, 1799, by one of the phyficians, 
from cows in Mary-le-bone-fielas and Gray’s-

Statement of Evidence collected from thefe 
fources on the queftion with which fome per- 
fons have agitated the minds of fo many fae 
families is intended to be laid before the pub- 
lic in a week or ten days. This fatement, it 
is apprehended, will be the moft proper returm 
to the refpe€table author,¢ who has lately 
addrefled his pamphlet ¢ Zo rhe Directors of 
the Vaccine Inftitution, very juftly conceiving 
that the point at iffue is within the power of 
this Inftitution, if they will give directions 
for a number of perfons to be inoculated with 
Small-pox matter, oz expofed ftrongly to in= 
fection, who were vaccinated early in the 
practice.” As no other profefled vaccine in- 
ftitution but this has been eftablifhed long 
enough to anfwer the demand, it has been 
determined to comply.” 
The ingenious Mr. CUTHBERTSON 
gives the following as the refult of many 
experiments in Galvanifm: (1) Charcoal 
was deflagrated and ignited for about one 
inch in length; (2) iron wire, 24; of an inch 
in diameter, was melted into a ball =. of 
an inch in diameter ; (3) platina wire, = 
inch in diameter, was melted intoa ball, 35 
inch in diameter; (4) brais wire, 34; inch 
in diameter, was ignited; (5) brals, 7: 
‘inch diameter, was red hot at the extre- 
mity; (6) iron wire, ++, inch in diameter, 
was red hot for 16 inches in lengths 
(7) iron wire, 12 inches, deflagrated and 
melted into a ball; (8) iron wire, fix 
inches in length was deflagrated; (9) 
iron wire, eight inches in length was 
ignited, Tavo troughs, each containing 
30 pair of plates, fix inches {quare, were 
ufed for the firft feven experiments ; and 
one of thefe troughs only for the laft two 
experiments. The four laft experiments, 
Mr. Cuthbertfon thinks, go to prove, that 
double quantities of Galvanic fiuid bura 
double lengths of uire, and not the /quare, 
as electrical charges do.

Mr. J. BramMaH has invented a new 
jib. ‘The peculiar conftruétion confifts in 
perforating the axis or pillar of the crane, 
ON Oe eee 
inn-lane, with the addition, about three years 
ago, of matter from the Milanefe by Dr. 
Tacco But it-does not appear that this ex- 
tenfive fucceflion has at all altered the pro- 
perties, nor that there is any difference of 
properties amongft thefe different fources of 
matter. The experience of this Inftitution does 
not juftify the conciufions, that the failure 
of the Cow Pock in preventing the Small 
Pox depends in general upon the felection 
of matter on a particular day.
