ozone, autozone changes at once to oxygen under the influence of 
heat. From dry electrified air autozone speedly disappears. But 
the remarkable distinction of this new aspirant for honor is its 
cloud-compelling power. Autozone sways its scepter over the 
waters, and lo, by a wave of its magic wand, fogs arise and 
vapors condense to clouds. We have thus a god of mists, whom 
the denizens of the Atlantic and Pacific slopes might do well to 
propitiate. That the forces of autozone are not of the fancy 
rnerel} 7 , we can easily prove. We pass a volume of air loaded 
with this gas through a quantity of water, and lo, an artificial 
mist is at once produced. Let the blind old bard of Scio sing of 
the “ cloud-compelling Jupiter.” Modern science has imprisoned 
the true Ariel of the clouds, causing him, Samson-like, to make 
sport for the human denizens of the air. The lover of the fra¬ 
grant “ Havana ” little realizes what imp from the air depths 
artistically curls the white cloud of smoke which issues from his 
mouth. The artist delighting in the white smoke wreaths grace¬ 
fully rising from the cottage chimney, little realized that the 
white smoke of the chimney owes its very existence to the 
presence of autozone, which always appears in large quantities 
whenthere is low-smouldering combustion, and with moisture 
forms the characteristic cloud. 
Probably all clouds and mists owe their existence to this power¬ 
ful gas. It unites chemically with water forming the peroxide 
of Hydrogen. Now this air of ours is at times filled with noxious 
matters unfriendly to all breathing animals, and kindly nature 
removes the dangerous atoms by frequent washings. 
Heavy rains clean the air of malarious germs and of mineral 
and vegetable dust, also washing from the atmosphere the nitric 
acid formed by electric discharges and the carbonate of ammonia, 
which, percolating through the soils until they reach the root¬ 
lets of plants, supply the nitrogenous substances, which in grains 
and fruit from the food of which the flesh of animals is made 
and which the leaves of plants are incapable of absorbing direct¬ 
ly from the air. 
It is thus seen that the atmosphere is the marvelous conserva¬ 
tor of animal and vegetable life, the vast storehouse from 
which the food of all living organisms is derived. On this we
