 of the Seventh International Zoological Congress. Upon the invita- 

 tion of a committee representing many of the scientific and educational 

 institutions of Philadelphia, and which held its meetings at this 

 Academy, a large delegation from the Congress, including upwards of 

 seventy foreign members, visited this city on September 2 and 3. 

 Among the visitors were many distinguished zoologists, including two 

 correspondents of the Academy, Dr. Raphael Blanchard, of Paris, and 

 Prof. A. A. W. Hubrecht, of Utrecht. The programme of entertain- 

 ment was very successfully carried out, both at the Academy and the 

 other institutions that were visited, and was very enjoyable to visitors 

 and hosts alike. 



An increased number of letters requesting information on subjects 

 of scientific interest were received and answered.
