NOTICE TO SECOND EDITION. 



The 'negatives' of this work and all interest and copyright having passed into 

 my hands, I have, in consequence of numerous demands for copies resolved upon 

 the reissue of the entire Avork, as originally published — so that all references and 

 quotations heretofore made to plates, figures, or descriptions will equally apply to 

 the present, which I trust will be found in no way inferior to the first edition.
