Mr. F. Alger, member of the Society, read an interesting 

 paper on the identity of the Beaumontite of M. Levy, and 

 the Lincolnite of Prof. Hitchcock, with Heulandite, and 

 illustrated his remarks by differently modified crystals of 

 these substances, specimens of which he laid before the 

 members. # 



The derivation of the secondary forms of the Beaumontite, from 

 the primary right oblique-angled prism of Heulandite, was very 

 clearly proved, and the source of fallacy pointed out, by which Mr. 



• Mr. Levy read his paper before the Academy of Sciences, Paris, and an 

 abstract of it may be seen in the Lond. and Edinb. Mag. for February. 1840.
