i2 4 THE MAIN CURRENTS OF ZOOLOGY 



Carnegie Museum at Pittsburgh, the collections of 

 the Philadelphia Academy of Sciences, the National 

 Museum and the Smithsonian Institution at Wash- 

 ington. 



Zoological gardens exist in New York, Washing- 

 ton, Philadelphia, Chicago and at other places. 



The embryological collection of the late Dr. Charles 

 Sedgwick Minot of Boston and of Dr. Franklin P. 

 Mall (died 1917) of Baltimore are of great service to 

 investigators in embryology. 



The entomological bureau at Washington, D. C, 

 and several of the State Entomologists have done 

 much to advance and to spread broadcast the 

 knowledge of Insects. The sumptuous publications 

 of the United States government have placed in hand 

 many valuable reports on animal life and animal in- 

 dustry. The activities and publications of the 

 United States Fish Commission are also notable.
