Application and Contact. From which it appears very 
probable, that a Perfon who has already had the Small 
Pox, as the Man inoculated by Mr. Tanner in St. Tho* 
mas's Hofpital, may poffibly receive it again in fome 
flight Degree by Inoculation ; that being flill a more 
dole and immediate application of the Variolous Mat- 
ter to the Blood and Juices of the found Perlbn, than 
when it is applied only by Contad: to the. Skin whole 
and unvvounded. 
adly. That the Infedion communicated to rhis Wo- 
man not being univerfal,as appears from her having no 
Fever, or Sicknefs, or general Eruption of the Pultules 
all over her Body, but only on the Parts infeded by 
immediate Contad, no Argument can be drawn from 
hence, for a Perfon’s being liable to undergo the Small 
Pox a fecond time, fo as to have the ufual Symptoms 
of that Dileafe, and a general Eruption of the Puftules ; 
but rather the contrary. 
Sdly, That the Time in which this Infedion fhew’d 
itfelf, by the appearance of the Puftules, is very diffe- 
rent from that obferved upon Inoculation ; the firft 
appearing in about a Day and an half ; whereas in the 
latter Cafe, the Eruption generally fliews itfelf on the 
tenth Day, or not above a Day fooner or later, as ap- 
pears from the accurate and curious Oblervations of 
Dr. Nettleton. Which difference is what ought in rea- 
fon to be expeded, fince in one Cafe the Infedion 
went no further than the Parts affeded by immediate 
Contad ; whereas in the other it muft be propagated 
thro’ the Mafs of Blood to all Parts of the Body.
