The mineral called Meneghinite, after Professor Meneghini, of Pisa, was originally dis- 
covered at Bottino in Tuscany, and first analysed by Professor C. Becchi.* Subsequently 
it was found near Schwarzenberg, Saxony, and analysed by Frenzel,t while recently it 
has been met with in Canada and analysed by the writer, who is indebted for the speci- 
mens examined to Mr. Fred. Miller, B. A. Sc. The Canadian mineral occurs near Marble 
Lake, in the Township of Barrie, Ontario. It is apparently from a vein with gangue of 
quartz and dolomite, and several of the specimens show a little adherent mica-schist, 
which is probably the country rock. It is massive, has a brilliant metallic lustre and a 
lead-grey colour and streak. The hardness is 2.5 or a little over, and the specific 
gravity, 6.33. The composition is given under I, while Vom Rath’s analysis of the Tus- 
cany mineral is given under II. :—

The correspondence, it will be seen, is very close, and both analyses agree approxi- 
mately with the formula Pb:Sb:8;. According to Vom Rath, the Tuscan mineral is 
monoclinic. No crystals of the Canadian variety have yet been observed, but a careful 
examination of the locality might perhaps reveal their existence. 
It should be mentioned here that Professor Chapman, of Toronto, some years ago called
