Wheat on the fixth; white Muftard-feed on 
the eleventh; but Beans, treated in the fame

many more plants that might be enumerated, 
would be foon deprived of the vegetative. prin- 
ciple. On the contrary, we may venture to 
affert, that, if fuch feeds will not putrify with 
the fummer temperature of the ground, at the 
depth of five or fix inches, when placed out of 
the reach of the air, they will immediately ve- 
getate upon being again expofed to its influence. 
This is at leaft a plaufible explanation of the 
phenomenon ‘in queftion. But in order to put 
it to the teft of experiment, I took fome feeds 
of Broom, which had been foaked for three 
days in water, on the fifteenth of Auguft ; and, 
after mixing them with moift fand, filled a 
{mall phial with the mixture. The phial, being 
well corked and wrapped in paper, was kept to 
the thirteenth of September, in a room’ where 
the thermometer was commonly at 65° and 
fometimes rofe to 70°. Thefe feeds, being 
planted afterwards in a pot filled with cakes 
vegetated.
