The chickens from the ovens are kept, in 

 Egypt, on the flat roofs of the houses, which

In France, Reaumur, who first brought 

 the thermometer to its present degree of 

 perfection, conceiving that he had, in that 

 instrument, the means of regulating the tem- 

 perature, made many experiments, and suc- 

 ceeded in raising chickens by means of 

 dung in a state of fermentation, and by ap- 

 propriate boxes over common ovens. Cham- 

 pion and Bonnemain still farther improved 

 and simplified the process, by making use 

 of tubes, with heated water. 



Latterly, a machine with all these im- 

 provements, and under the name of Eccale- 

 beion, has been introduced into England, 

 where it has been in successful operation.
