DIVISION OF MINERALOGY (Geological Survey) 
Eugene Poitevin, Chief of the Division, reports: 
The Division of Mineralogy is a division of the Geological Survey, but 
it has important functions to perform in connexion with the National 
Museum of Canada. These functions consist in collecting and exchanging 
mineral specimens and placing them on exhibit, making contributions 
to the scientific investigations of Canadian minerals, and promoting the 
knowledge of mineralogy by means of publications, lectures, and the 
distribution of mineral collections to educational institutions. 
More than 3,000 mineral specimens were added to the systematic and 
economic collections. A fine set of mahogany table cases having been 
completed, twenty cases were filled with exhibits and plans were made for 
further exhibits. 
In addition to identifying a large number of specimens for the system- 
atic collection, the mineralogists of the division contributed the following 
studies to Canadian mineralogy. 
Eugene Poitevin studied a large suite of specimens from the serpentine 
belt of the Eastern Townships, Quebec, the principal ones being perovskite 
from lake Nicolet, and prehnite, natrolite, scolecite, diopside, albite, 
grossular garnet, etc., from Thetford asbestos mines. He also investi- 
gated a new mineral from British Columbia. 
H. V. Ellsworth nearly completed the writing of a report on the rare 
earth minerals of Canada, and also published the following papers: 
Thucholite, a remarkable primary carbon mineral from the vicinity of Parry Sound, 
Ontario. 
Cyrtolite intergrowth associated with the Parry Sound thucholite. 
Thucholite and uraninite from the Wallingford mine, near Buckingham, Quebec. 
Euxenite from Sabine township, Nipissing district, Ontario. 
Zircon from North Burgess, by C. Palache and H. V. Ellsworth. 
A simple and accurate constant volume pyknometer for specific gravity determinations. 
R. J. C. Fabry, analyst, made a number of complicated analyses of 
minerals such as topaz, beryl, and margarodite from the Silver Leaf mine. 
He also undertook the study of perovskite and ilmenite from the serpen- 
tines of lake Nicolet in the Eastern Townships of Quebec. He made
