pox. Now, in the hiflory of fmall pox 
inoculation, there are feveral ungucftion- 
able inftances of the recurrence of the 
difeafe in the fame fubject; thefe aré ano- 
malous cafes, and before the difcovery of 
the vaccine, it would have been juft as 
rafh to have rejected variolous inocula- 
tion, becaufe one fubjet in fifteen or 
twenty thoufand had been fufceptible of 
the: difeafe a fecond time, as it is now to 
reject the vaccine inoculation, becaufe one 
fubjeét in fifteen times fifteen or .twenty 
thoufand was unfortunate enough to re- 
ceive the fmall-pox after vaccination. 
In confequence of Mr. Goldfon’s pam- 
phlet, Dr. Jenner has thought it incum. 
bent on him to fubmit his-earlieft cafes of 
cow-pox to the variolous tet: Mr. D. 
quotes a letter from the Door on the 
fubjeét, dated July 22d, i804.—* The 
trials (fays he) I have lately inftituted 
here, affifted by my nephews, I can af- 
fure you, have been fevere ones—but, 
thank Heaven! they have been decifve ; 
and, without apy other aid, mut com- 
prey overthrow the argument of Mr. 
oldfon. All the fubjetis that I could 
collect, who were vaccinated at the com-- 
mencement of my praétice here, men, 
women, and children, have been iately ex- 
pofed to the fmall-pox, in a ftate as highly 
contagious as poffible: they were taken 
into aroom, and went to the bedfide of a 
woman covered from head to foot with 
puftules. All have efcaped unhurt, ex- 
A 
great number of thefe had been inoculat- 
ed fix yearsago. Phipps too, the boy on 
whom I made the firft trial, more than 
eight years ago, has again been put to 
the teft with impunity.” 
“* Statement of Evidence from Trials 
by Inoculation by variolous and vaccine 
Matter,’ publithed by the phyficians of 
the original Vaccine Pock Inftitution. 
Statements of thele trials were made ex- 
prefsiy in corffequence of Mr. Goldfon’s 
publication, and the evidence is now 
brought forward to allay the public anx- 
iety on the fubject. “The experiments are 
moft of them detailed at length, but we 
have only room to {tate the genera] refult. 
Thefe trials thew, ‘* that above fifty per- 
fons who had been vaccinated from three 
to five years ago, and ten who had been 
vaccinated at a later period, were incapa- 
ble of taking the fmall- pox by inoculation, 
In circumftances chofen as moft favoura- 
ble for infegtion. For many of the fub- 
jects were expofed to the cffluvia fiom 
{mall pox patients; they were all inecu- 
dated in three tines the ufual number of 
places ; they were all inoculated with eff- 
Cacious and recent matter, and with ma- 
ny of them unufual pains were beitowed 
to introduce the matter quite fluid, imme- 
diately from the variolous patient. In 
thefe it feems fair to calculate, that nor 
more than one, or, at moft, two of thefe 
fixty perfons, would have eltaped the 
fmall-pox, if they had not already gone 
through that difeafe, or its vicarious affec- 
tion, the cow-pock.” 
Dr. Bostock, of Liverpool, has pub. 
Jifhed the frft and fecond parts of a very 
ingenious and fcientific ** Efazp on Refpa- 
ration.’ The whole work he divides in- 
to three parts; of the two which are pub- 
lifhed, the firflas employed in defcribing 
the procefs of refpiration. Here Dr. 
Boffock gives an account of the various 
organs which unite to perform their func- 
tions; the lungs, the trachea, with its 
various ramifications, the puimonary fyf- 
tem of janguiferous veffels, and the dia- 
phragm. He then treats of the mecha. 
nifin of refpiration, which eonfilts in the 
reception and emiffion of air into, and 
out of the branchial veflels of the lungs, 
by means of the alternateenlarzement and 
contraction of the cavity of the thorax. 
He then enters into an enqsiry concern. 
ing the bulk of a fingle refpiration, and 
the capacity of the therax in its different 
fiatesof difenfion. The caufe of the firtt 
infpiration, and of the alteration of in- 
fpiration and expiration, is afterwards | 
confidered. 
The fecond part points out the direét 
effects of refpiration, which Dr. Boftock 
arranges under three div.fions. 1. The 
mechanical effects produced by the dilata- 
tion.and contratticn of the thorax. 2. The 
change produced -in the infpired air. 3. 
The alteration which the blood experi- 
ences in its paflage through the capilla- 
ries of the lungs. , 
In the third part (which is not yet pub- 
‘ithed) Dr. B. propefes to confider the dif- 
ferent modes and degrees in which refpi- 
ration is affected; whether fuch aficétiom 
is occafioned by the various natural fitua- 
tions in which the hody may be placed, 
or by the effeis of morbid caufes operat- 
ing on the fyftem. 
clude by inyefligating the ules of refpira- 
tion, and by an attempt to afcertain its 
conneétion with the other annnal func- 
tions.
