Among species new to the collection, the Vaux-Academy 1921

keeleyite, daubresite, sphaerite and rhomboclasite, of which the 
first three are new species, described during the year by Mr. Samuel

Other minerals not hitherto represented in the collection, include 
ferriente, presented by Dr. W. F. Ferrier; haidingerite, invoite, 
hulsite and orientite, obtained by exchange; and the following,
