They present also considerable resemblance to his slides of " Pitchstone porphyrite " from the Cheviots, especially from Carl Croft, Blindburn, Fernhaugh, Windyhaugh, Cognet, and Alvin ; and to one of the same rock (though less close) from a foreign locality, Vethalm. I also note a resemblance to an anorthitetrachyte from Matra, and from Borac (S. Servia) in my own collection. There are also resemblances macroscopic and microscopic to some specimens brought me by Mr. Whymper from Antisana,...

Page 82 - Nature as sulphides or double sulphides (also as selenides, tellurides and arsenides), ie in combination with a negative element belonging to an odd series, and only in very few cases as oxides, whereas elements belonging to even series, on the other hand, usually occur as oxides or double oxides (forming silicates, carbonates, sulphates, aluminates, dtc.), ie in combination with a negative element belonging to an even series, and never (with two exceptions) as sulphides.

Page 83 - ... odd series on the other. The halogens Cl, Br, I and F, being the most electro-negative of the elements, occur in nature in combination with the most electro-positive metals as chlorides, bromides, iodides and fluorides, &c. and are never (if we omit a few metallic oxychlorides and sulphochlorides) found in combination with either oxygen or sulphur. The only other point necessary to mention is that as regards the odd members of any one group, the tendency to occur in nature as sulphides increases,...
