224 The new Infeft. 



lated fmall-pox.— 4. None of the patients, rianiely, above 

 faty, hitherto inoculated for the fmall-pox, fubfeqtiently to 

 the vaccine difeafe, took the infection. — 5. One of the molt: 

 important facts is, that the local affection in the inoculated 

 part, on the whole, was left confiderable, and of fhorter du- 

 ration than in the inoculated fmall-pox. — 6. In many of 

 the cafes eruptions on the body appeared, fome of which 

 could not be diilinguifhed from the fmall-pox. 



T have fent the matter of the cow-pox puftule on the 

 thread inclofed, in order, if you approve of the inquiry, t« 

 inoculate with it ; and I entreat you to favour me with the 

 refult of your trials : but I mull trouble you to apply the teft 

 of inoculating with variolous matter fubfequently to the vac- 

 cine diforder. 



I have the honour to be, &c. &c. Sec.

P. S. I am happy to be able to flatc, that at Berkeley 

 Dr. Jenner has continued his trials of inoculation with vac- 

 cine matter, fent from London, with good fuccefs. — I mould 

 have given you a more circumftantial account of the cafes 

 here alluded to, but I think it unncceffary, as Dr. Wood- 

 ville has a pamphlet in the prefs on the fubject. 



THE NEW INSECT. 



IN our laft we informed our readers that a new infect had 

 appeared within thefe few years in this country, which 

 threatens the entire deftru&ion of all our apple-trees, if 

 means be not generally followed for extirpating it. In the 

 hurry of the prefs a material ingredient was omitted in Mr. 

 Forfyth's recipe : we therefore reprint it more correctly. 



R. To 100 gallons of human urine and 1 buihel of lime 

 add cow-dung to bring it to the confluence of paint. With 

 this compofition anoint the trees. The prefent is the proper 

 feafon for applying it. If the white cfflorefcence-like fub- 

 ftance in which the infects are lodged has made its appear- 

 ance, it mould previoufly be brufhed off.
