confiderable uncertainty might remain to the practitioner; 
Mr. SLoper was defired to procure from Mr. Gorpon an

To the SECRETARY. 
SIR, Moore-Place, Jan. 16, 1797. 
ie confequence of a letter I received from Mr. 
Storer, who I requefted would do me the 
favour of looking over the courfe of experiments 
that had been made to cure the Smut in Wheat, and 
which I had communicated to you, I trouble you 
with this. He fent me feveral queries, which were 
neceflary to elucidate the procefs of the experiments. 
The other fide of this contains the anfwer to them, 
from my friend Mr. Jennines, whofe care and 
accuracy in going through thefe experiments, and 
their fuccefs, make them highly deferving the pub- 
lick attention.

I an, fir, 
Your moft obedient humble fervant, 
JAMES GORDON, jun.
