served from Jight, and yet supplied with oxygene. 
I have counted from forty to one hundred and 
twenty stalks produced from a grain of wheat, ia 
a moderately good crop of drilled wheat. And we 
are informed by Sir Kenelm Digby, in 1660, that 
there was in the possession of the Fathers of the 
Christian Doctrine at Paris, a plant of barley, which 
they, at that time, kept by them as a curiosity, and 
which consisted of 249 stalks springing from one 
root, or grain ; and in which they counted above 
18,000 grains or seeds of barley. 
The great increase which takes place in the 
transplantation of wheat depends upon the circum- 
stance, that each layer thrown out in tillering may 
be removed, and treated as a distinct plant. In 
the Philosophical Transactions, vol. lviii. p. 203., 
the following statement may be found: Mr. C. 
Miller, of Cambridge, sowed some wheat on the 
2 d of June, 1766 5 and on the 8 th of August, a 
plant was taken and separated into 18 parts, and 
replanted ; these plants were again taken up, and 
divided in the months of September and October, 
and planted separately to stand the winter, which 
division produced 67 plants. They were again 
taken up in March and April, and produced 500 
plants : the number of ears thus formed from one 
grain of wheat was 21,109, which gave three pecks 
and three quarters of corn that weighed 47lbs. 7ozs. 5 
and that were estimated at 576,840 grains. 
It is evident from the statements just given, that 
the change which takes place in the juices of the 
leaf by the action of the solar light must tend to 
increase the proportion of inflammable matter to
