PREFACE. 



J. Rothschild, Editeui'. In addition to these books, I have 

 consulted Science Gossip and Gassell's Natural History. There 

 are other books whose names and authors I have forgotten, 

 but some of the useful information which I obtained from 

 them I remember, and for it I am grateful. But the correct- 

 ness or inaccuracy of whatever information I have gained 

 from books or articles, I have tried to prove by practical 

 experience.
