REPORT OF THE MIXERALOGICAL SECTION. 



The Director of the Mineralogical and Geological Section would 

 respectfull}^ report that regular meetings have been held monthly 

 during the year, except in July and August. At these meetings 

 the attendance of members and visitors has been larger than in 

 any former 3 ear, averaging eleven. Xew discoveries have been 

 from time to time announced, and many items of interest discussed. 

 For the details of this work he would refer to the appended reports 

 of the Professors of Invertebrate Palaeontology and of Mineralogv, 

 and to the papers herewith transmitted, and which will be pub- 

 lished in the Proceedings for 1882. Specimens received through 

 the section during the 3'ear, though not as large in number as in 

 some prior 3'ears, have made a valuable addition to the cabinet. 

 A special meeting was held in March, in conjunction with the 

 meeting of the Academy', at which the Professor of Mineralogy 

 delivered his inaugural address. Two hundred members and 

 visitors were present, 



The success of this insured the unanimous approval b}' the 

 Section of the proposition to combine the meetings of the Sections 

 with those of the Academ}'. 



The following officers have been elected for the ensuing year: 

 Director, .... Theo. D. Rand. 

 Vice-Director, . . . W. W. Jefferis. 

 Secretary, .... Chas. Schaeffer, M. D. 

 Treasurer, .... John Ford. 

 Conservator, . . . . H. Carvill Lewis. 

 Respectfully submitted. 



Theo. D. Rand, 



Director.
