3, O&. 19, 1792, fowed rb. fteeped 20 hours, 
in one quart of water, to which was added one 
ounce of oil of vitriol, and fown wet:—a few 
ears of fmut. " 
3d, rb. of ditto, with two ounces of oil of vitriol: 
—only two ears of mut. 
4th, 1lb. of ditto, with three ounces of dittoz— 
perfecily found. 
sth, 1lb. fteeped 20 hours in ftrong brine:— 
very fmutty, nearly half and half. 
N.B. By {trong brine, I mean to bear an egg. 
6th, +b. fteeped 20 hours in ftrong lime-water: 
—a little fmut, enough to tail the fample.

thirds were fmut. 
I feel myfelf bound in juftice to mention, that I 
had the firft hint of the ufe of oil of vitriol, ina con-

at Toddington in Bedfordfhire. I have to obferve 
here, that in this, and in all my experiments, the 
brine feemed always to injure the plants through 
the whole of their progrefs, from their bemg fown 
till harveft; but as it in fome degree wafhed the 
feed, the produce by this means might be thelefs 
fmutty. As this experiment feemed to be very 
fatisfatory, with regard to the good effect of oil of 
vitriol
