Abstract

I WILL reply seriatim to the various points of Prof. Tarr's letter. (1) Term “Mineraliser.”—I still think the word objectionable in the sense used by Prof. Tarr. To most people it probably conveys the idea of something which converts or helps to convert another substance into a mineral. How can sulphur be said to “mineralise” silver by combining with it? Both the elements already exist as minerals in nature; and one might just as well say that the silver mineralised the sulphur.
