1883.] 645 



Prof. Cope communicated a paper entitled " Fourth Con- 

 tribution to the History of the Permian Formation of 

 Texas." (See page 628.) 



The action of the Curators was approved in regard to 

 lending for scientific examination the Mexican flutes belong- 

 ing to the Cabinet of the Society, deposited at the Academy 

 of Natural Sciences. 



Dr. Frazer took occasion from Dr. Brinton's remarks 

 prefatory to the reading of Prof. Crane's paper, to ex- 

 press his views regarding the presumptive restriction 

 of authors of papers from using already published matter 

 in said papers. Mr. E. K. Price and Mr. Fraley ex- 

 plained the habitually liberal policy of the Society in respect 

 of communications made for publication. Mr. Lesley ex- 

 pressed the hope that the broadly " philosophical " character 

 of the Society would be maintained, and that the Proceed- 

 ings would not become restricted to the narrow limits of 

 !N"atural History or the Physical sciences, so called, but that 

 the Society would encourage its members to communicate 

 for publication their best mature thinking in whatever de- 

 partment of human knowledge they might engage.
