Summary of Papers 



The progress of the Academy's Natural History Survey of Porto Kico 

 was siunmarized in the pa})ers as follows : 



Professor Berkey outlined his geological reconnaissance of the island, 

 in which he and Dr. Fenner had traveled over 2,000 miles; they had 

 studied the rocks at so many points that they were enabled to construct 

 a preliminary geological map which was much more accurate than any 

 hitherto made; from their studies the broader geological history of the 

 island was revealed. 



Professor Britton outlined the progress of the botanical investigation. 

 The material collected by the Academy workers had been distributed to 

 a number of specialists in different parts of the country and from their 

 labors the knowledge of the flora was rapidly extending. 



Dr. Howe by means of the stereopticon exhibited a series of marine 

 algse recently collected by himself. Especially interesting were the reef- 

 building corraline algse.

 Mr. Miner described the results of his collecting of marine invertebrates ; 

 Dr. Lutz outlined the present knowledge of the insects and spiders,
