From the above values, Messrs. Smith and Brush have deduced 
the annexed formula :—2 [38 (MgO, FeO), PO®] + 5 Al?05, 3

Turquoise, Lazulite, Wagnerite, Herderite, Amblygonite, Monazite, 
Xenotime, and Cryptolite.

FOREIGN MEMBER OF THE GEOLOGICAL SOCIETY OF LONDON. 
[The general interest occasioned by the recently admitted occurrence of extinct 
remains in association with objects of human art, induces us to transfer to our 
pages the following interesting letter from the pen of M. Lartet, published, with 
some additional notices by Mr. Leonard Horner, in a late Number of the Quar- 
terly Journal of the London Geological Society (No. 64, November 1860.) By
