/JyANURE FROM THE AlR BY ELECTRICITY.— 
For some time past we have been 
receiving the more sensational reports in 
the matter of science from Vienna. The 
most recent from that source was the 
production of peptone or albuminous matter 
from a few simple elements by a synthetic 
process. The object was the production of 
human food by artificial means. The great 
feature of the presidential address at the 
meeting of the British Association at 
Bristol on the 7th inst. was the idea of the 
production of nitrate from the atmosphere 
by artificial means. Sir William Crookes, 
F.R.S., the president, in his opening 
address discussed the problem of manufac¬ 
turing nitrate by electricity, in sufficient 
quantity to be used as a manure for in¬ 
creasing the quantity of wheat per acre. 
This idea may not at first blush be so 
sensational as the report from Vienna, but 
it is more feasible. At the present rate of 
the consumption of wheat, and the present 
rate of increase of the population, the world 
will only be able to supply the demand 
till 1931, after which the human population 
of wheat eaters must starve, or devise 
means whereby the average rate of produc¬ 
tion will be greatly increased. The area of 
the globe capable of producing wheat cannot 
be stretched, but culture can be intensified 
to a certain impassable limit. 
This question of the production of suffi¬ 
cient human food to meet the requirements 
of the human population is a stupendous 
one, and nothing so great in this particular 
line has been advanced since Joseph inter¬ 
preted Pharaoh’s dream, prophesying seven 
years of plenty and seven years of famine in 
the land of Egypt. The modern wizard of 
the north, Sir William Crookes, has tackled 
a subject of vastly greater importance, since 
it concerns not merely a nation or country, 
but the whole wheat-eating population of
