CATALOGUE. — ECOVOMT OF HEAT, 



411 



Equal parts of muriate of ammonia and nitre, dissolved 

 in water, sink the thermomclcr about 40", and may be 

 dried again. Phosphate of soda 9, nitrate of ammoniac, 

 dilute nitrous acid 4, depress the temperature from so" to 

 — 21°. Muriate of lime 3, snow 2, sink it from 32° to- 

 -^50"; caustic potash 4, snow 3, to — si". Ice ground to 

 powder with a centrebit is better than snow, frozen vapour 

 than either.

One pound of pine wood burnt raised the temperature 

 of 20.1 pounds of water 180 degrees : from Kirwan's com- 

 parison the same quantity of pitcoal would raise 36 pounds 

 of water in the same degree, and a pound of charcoal 57.6 

 pounds. According to Lavoisier, equal heats are produced 

 by 403 pounds of coke, 600 of pit coal, 600 of charcoal, 

 and 1089 of oak wood. In general | of the heat of the 

 fuel employed are wasted.
