can obtain a fresh supply of the vaccine matter early in the spring, 
the inoculation for it will sink into disrepute, and I myself come 
in for a-large portion of the disgrace. 
* Judge of my anxiety when | say that I am conscious that more 
than one hundred practitioners in different parts of New England 
are at this time inoculating with spurious matter, while the small- 
pox is pervading one of our sea ports, and every unfortunate case 
will be traced up to me, the originator of the practice in America. 
I am the only person who ever succeeded in obtaining efficient 
matter from England, which I had from Dr. Haygarth, and the 
activity of this matter seems worn out Ly passing through a number 
of the human species ; and unless [ obtain a fresh supply from Eng- 
land, the business which promised so fair here will stagnate. I 
have, therefore, written to Dr. Jenner for his advice and assistance, 
So I have to Dr. Pearson; and hope by the return of the Galen 
or by the Minerva to get a supply of the matter I stand so much in 
need of. I have just received an order from the War Department 
to supply the military surgeons with the vaccine matter, and direc- 
tions for inoculating the different corps of artillerists and engineers 
stationed in the various parts of New England.”
