48 On the Egyptian system of Artificial Hatching. [Jan. 



Before I conclude this brief account, I would just mention that this 

 artificial mode of hatching will apply equally to turkey's eggs. Several 

 Europeans had put them into the ovens in Egypt, and a few did suc- 

 ceed in being hatched, but Arabs being totally ignorant of the prin- 

 ciples of the oven-hatching, they subjected them to the same condi- 

 tions as fowl's eggs — hence the failure of the greater number. But that 

 they might be hatched artificially was evident from some of the eggs 

 which were put in having been hatched. By this means the supply 

 of turkeys would also be cheap and abundant. 



I have no doubt that if this artificial hatching of turkeys as well 

 as fowls were introduced into any country, and commonly adopted in 

 farm houses, it would tend greatly to the advantage of the land.
