VACCINE INOCULvNTION. 



N our lafl \vc iiieiitioned that Dr. Sacco, of Milan, hafl 

 fent to Dr. Fcarfoii cow-pnck m;Utcr taken from the Mi- 

 lanefe cows. In a work pubHnicd bv Dr. Sacco, iu Italian, 

 entitled, Praftical Obfcrvations on the Ufe of the Cow-pock, 

 as a Prefervative againft the Small- pnx, he gives the follow- 

 ing account of the manner in which he procured the pus for 

 inoculation, and alfo a reprefentalion of a cow's udder in- 

 fetled with the malady. (See Plate VI.) 



" For fomc lime I had been extremely defirous to repeat 

 the experiments of .tenner, and for ihi.s purpole made diligent 

 fearch to difeover the cow-pox in Lombardv, it being ex- 

 tremely difficult, efpecially in the prel'cnt eircumftances, to 

 obtain the pus from England. A fortunate combination of 

 circumftances, bv which it became necetVary for me to goto 

 the large town of Varefe, in the beginning of autumn, pro- 

 cured me an opportdnitv of examining a number of cows on 

 their way from vSwitzerland to the fair of Lugano ; and by 

 this means I had a favourable opporlunitv to make fuch re- 

 fearches as might difeover in fome one of them the cow-pox. 

 It was on this occafion, that, converiing with fcmie dealers in 

 cattle, and countrymen who had large dairies in Lower 

 Lombardy, I learnt that the cows among us are fubjecTt to 

 the cow-pox. In this inquiry I took care to piopoie my 

 queftions in fuch a manner as to prevent the riik ot being 

 impofed upon. A farmer ot Cremona, vvho had bought forty- 

 cows in Switzerland, and had driven ihcm from thence as 

 far as \'arefc, aflured me that almoft all of them had been 

 fucccflively attacked with putiules on the extremity of their 

 nipples, and fome of thcfe were now converted into incrulta- 

 tions. 1 vifited the covvs, and had an opportunity of verity- 

 jng his aflertions. I picked Ofl" fome ol tliefc ineruftatiuns 

 with an intention of applying them in fomentation, if, per- 

 chance, I could not procure the true pus for inoculation. 

 The fame farmer promifed me an opportunity of feeing this 

 difeafe with my own eyes, and for this purpofe conducted 

 me to a neighbouring meadow, in which we found a lierd 

 of cows belonging to a friend of his. We examined ihefc 

 cows, and dii'covered on two of them difierent red fpots, 

 which the farmer allured me was the llrft llage of the difeafe: 

 no other fymplom appeared on the cows, but a flight degree 

 ofdcje6lion. I:ie allured mc that this was the very diicafe
