MINERALOGY. 
1. Triphylme, a new mineral.—Professor Fuchs, of Munich, has 
discovered in Bodenmais, Bavaria, and described under the name of 
Triphylme, a new mineral, which consists of the Phosphates of iron, 
manganese and lithia.—L’ Institute, March 11, 1835. 
2. Hydroboracite, a new mineral—Colour white, radiated 
and foliated, and soft like gypsum. Specific gravity=1.9. It 
is readily distinguished from such minerals as it might be con- 
founded with, by its easy fusibility before the blow pipe. Ac- 
cording to H. Hess, it contains the following ingredients ; Lime 
13.298, magnesia 10.430, water 26.330, boracic acid 49.922 ; 
=100.00.—Jameson’s Ed. New Phil. Jour. April, 1835. 
3. Diamonds at Algiers—The Sardinian consul at Algiers, 
M. Peluzo, lately purchased from a native three diamonds, which 
were found in the auriferous sand of the river Gumel, in the prov- 
ince of Constantine. One of them was purchased by M. Dufresnoy, 
the other two by M. Bronganiart, for the museum and collection of 
M. de Dreé.—J0. 
4. Allanite of Greenland.—This rare mineral occurs imbedded 
in the granite of Greenland, where it was discovered by the late 
Sir Charles Giesecké. Mr. Allan conjectured it might be a variety 
of gadolinite, but Dr. Thomson of Glasgow, who was furnished with 
specimens for examination by Mr. Allan, determined that, chemically 
considered, it must be owned as anew species, which he named 
Allanite, in honor of Mr. Allan. Thomson found it to contam, of 
silica 35.1, oxide of cerium 33.9, black oxide of iron 25.1, lime 9.2, 
alumina 4.1, volatile substances 4.0,=112.0. ‘The imperfection of 
this analysis, shewn by the excess of the constituent parts, rendered ~ 
a repetition of itdesirable. Fortunately the Allanite has been again 
analyzed by the celebrated Stromeyer, who gives the following as the — 
result of his analysis: Silica 33.021, alumina 15.226, protoxide of 
cerium 21.600, protoxide of iron 15.101, protoxide of manganese 
0.404, lime 11.080, and water 3.000 ;=99.432. It follows from 
this analysis, that the Allanite, although in composition nearly allied 
to the orthite of Berzelius, différs from it in not containing yttria. 
It is still uncertain if the Cerin of Haidinger is the same mineral as 
Allanite ; and it is equally doubtful if the mineral from the Mysore, 
analyzed by Wollaston, belongs to the Allanite species.—I0.
