DREER 



and had six children. Of the two sons, one died in infancy, 

 and the other, William F. Dreer, conducts, at 7U Chest- 

 nut street, the business which is incorporated in the 

 name of his father. Henry A. Dreer died of a nervous af- 

 fection of the heart. He was of modest temperament 

 and frail constitution, and confined himself to business 

 rather closely. He was liberal in public matters, but 

 always kept out of political life. He compiled several 

 small works in connection with the business, and wrote 

 frequently for the Weekly Saturday Evening Post, of 

 Philadelphia, and for Godev's Ladies' Magazine.

DETTPE. A fleshy fruit containing a single seed with 



a bony covering or "stone,"

 resembles an akene in being 

 1-sided, aud not splitting, but 

 an 5kene is dry instead of 

 pulpy or fleshy. The most 

 important drupaceous or stone
