To quickly assess the difficulty of the text, read a short excerpt:
1'HTHAMTK. 107 little opal. Mixed with the silica is ferric oxide or ferric hydrate, some- times in very uniform distribution and again in patches or streaks. The iron oxide is somewhat translucent and is soluble in dilute chlorhydric acid with a yellow color. The mass is ordinarily intersected by extremely nu- merous quartz veins. These are seldom more than 0. 5 miu in thickness, while the thinnest are often visible under the microscope as mere white lines of insensible width. The veins are us...ually continuous across the slide, but may sometimes be observed pinching 1 . When this is the case the fissure narrows very gradually as the point is approached, as is the case with fissures of all sizes in all rocks. There are nearly always, if not invaria- bly, two sets of fissures in the phthanites, crossing each other at a high angle, and all the phenomena are precisely similar to those accompanying torsional fracture as investigated by Mr. Daubrt'e. 1 Small dislocations of course inevitably accompany fractures of this description.
