 Dear sir: I transmit herewith for publication as a bulletin 

 of the State Museum a paper entitled Contributions from the Miner- 

 alogic Laboratory, prepared by H. P. Whitlock, Mineralogist of this 

 division. 



It is with some satisfaction that I communicate a paper, brief 

 in itself and wholly concerned with pure science, which constitutes 

 a really substantial addition to our knowledge of the mathematical 

 and physical characters of New York minerals. 



Very truly yours, 



John M. Clarke 



Director and State Geologist
