Evidently this needed further investigation; and this was done with minerals purchased from various dealers, care being taken to obtain them from different localities. Curves b and c give the transmission for transparent yellow crystals, t=o.^ and mm. respectively, which came from Arten, Thuringia. Curve d is the transmission for a grayish-white translucent crystal, ground to mm. in thickness, from Mallonka, Austria. Curve e is for a white transparent crystal, mm. in thickness

Curve e is for a white transparent crystal, mm. in thickness, from Tula, Russia. In all these curves it will be noticed there is no energy transmitted beyond. 10 345678 FIG. 17.—Cassiterite (a); Mellite. 10 3/i, while from the very nature of the transmission curves the band is invisible and the 2 /* band is almost obliterated. As a whole the theory that, in crystal-water, the bonding is the same as in ordinary water has also been confirmed with mellite. A letter of inquiry to Steeg and Renter in regard to the sample sent us revealed the fact that cassiterite (SnCX) was accidentally substituted for mellite. The fact that it was possible to detect the error would indicate that the method of analysis is trustworthy, and in that respect it is fortunate that the substitution Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
