Extract

This substance was found by Mr. Dudgeon at the Pibble mine, which is directly opposite to Cairnsmore of Fleet, in Kirkeudbrightshire, and is within a few miles of Creetown.

This mine was worked for lead, and a few pieces of copper-nickel (nickeline) were obtained at it. The blue variety of the silicate of zinc also very sparingly occurred, and there were slight appearances of the phosphate and of the carbonate of lead.

No. 12, Mai 1887, describes a similar Hydrocerussite from Lougban in Sweden. This M. Bertrand — Bull. Soc. Min. T. IV. 1881, p. 87, finds to be uniaxal. None of these Hydroeerussites have, I believe, been analysed. The Wanlockhead mineral Lacroix finds to be uniaxal, and apparently hexagonal.
