 able to obtain any pofitive refult; the principal caufc of 

 which, no doubt, has been, the difficulty of procuring matter 

 fufficiently recent. Our veterinary doftors do not feem to 

 be acquainted with this difcafe among cows. One inftance 

 only has occurred where they thought they obferved this difeafe 

 amono- thefe animals; and we embraced that opportunity of 

 colleftina; the virus, which was employed, together with mat- 

 ter received from Geneva and England, but hitherto without 

 any certain fucccfs. Wc find ourfelvcs, therefore, deprived 

 of the chief means necelTary for commencing our trials ; and 

 we addrefs ourfelves to you to affift us in procuring them.

 either; alfo, fome of thefe fcabs or puftules quit' freHi,

 ■local affcftion of the part inoculated. The diiferer- kinds of 

 matter or fubftances ought to be particularly r^rked. If 

 your method of preferving threads in azotic or vdrogcn gaS 

 feems to be attended with any advantage, w expeft from 

 your zeal that you will employ it. In conju^^'^'on with our 

 minifter for foreign relations, we have take every necelTary 

 meafure that the fafeft, the moft convcni-^t^ and, in parti- 

 cular, the fpeedicft mode of conveyanc ^'^11 be at your 

 command. The Society, with equal ejcrnefs, will make 

 known the fervices that you may rendcto 't, and commu- 

 nicate to you the refult of its refearche the merit of which 

 will in a great meafure belong to yo if, along with the 

 matter winch we requeft, you will h^ the goodnefs to add 

 fome particular inftruftions, which'C ftiall be very happy 



to follow. ^ J J .■
