ADVERTISEMENT TO THE FOURTH 

 EDITION. 



THIS Edition is printed from a copy of SALMONIA 

 which, had been revised by the Author shortly before 

 his decease. The few alterations, additions,, and 

 omissions which have been made, are either chiefly 

 from his dictation, or in compliance with instructions 

 expressed by him at the time. 



Some Notes are subjoined and appended, most of 

 them relating to facts recently ascertained ; they are 

 distinguished by being inserted in brackets, and by 

 the initials of the Editor.
