FirsT.CLass SiLver MEDAL at the Dusseldorf 
Exhibition, 1880. 
SILVER MEEAL at the Exposition Universelle, Paris, 1878. 
The SPECIAL ADVANTAGES claimed for these 
Machines—the working of which is based upon the vapori- 
sation of Anhydrous Ammonia and the re-condensation of 
the vapours by compression—manufa&ured under Linde’s 
System, are as follows :— 
1st.—Less Consumption of Fuel than by any other 
machine. 
2nd.—Less Consumption of Cooling Water as com- 
pared with any other system. 
jrd.—Comp ete Reliability and Simplicity of Action. 
The attendance of the machine does not require 
more time & attention than that of a steam engine. 
4th.—Solidity and Superiority of Construction, and 
no unusual wear and tear. 
sth.—Absence of Danger from Explosion. Ammonia 
is practically uninflammable. 
6th.—Liquid Ammonia is obtainable almost anywhere, 
and there is no difficulty as to its transit; whereas 
the chemicals used for most other systems are 
only procurable at special factories, and must be 
despatched in closed vessels subject to pressure. 
7th.—Inconsiderable Loss of Ammonia, in consequence 
of our specially constructed gland for the piston rod.

LINDE'S SYSTEM for the purposes of their trade, will be forwarded
