 ... Thirdly, squinting is a familiar example of hereditary transmission: it is frequently a result of such optical defects as have been above mentioned; but the more primary and uncomplicated forms of it are also sometimes in a marked degree transmitted in a family. Fourthly, CATARACT, or opacity of the crystalline lens, is commonly observed in persons whose parents have been similarly affected, and often at an earlier age in the children than in the parents. Occasionally more than one child in a family is thus afflicted, one of whose parents or other relations, presents the ...

... * As the opacity and porcelain-like appearance of the glands is probably due to the coagulation of the albumen, I may add, on the authority of Dr. Burdon Sanderson, that albumen coagulates at about 155o, but, in presence of acids, the temperature of coagulation is lower. The leaves of Drosera contain ...

... of all Billy's efforts the evening went wrong after that. Caroline was wrapped in a mantle of sorrowful meditation the opacity of which she was not willing to let Billy penetrate for a moment. After they had dined they took a taxi-cab up-town and danced for an hour on the smooth floor of one of the quieter hotels. Billy's dancing ...

... which hung over the town, and concealed the dome and tower from view—a blood-red cross appearing to shine in the heavens and rest upon Birmingham.

All the others, even the newly discovered cathode rays, are subject to obstruction by certain forms of matter; that is, to them certain forms of matter are opaque. But gravitation knows no opacity in the universe. No atom of matter is exempt from its sway. It streams through all obstructive media as though such media did not exist.

... towered like a giant's. His abundant red hair, waving thickly from his bulging forehead, redeemed by its single note of colour the rigidity of his features. His eyes—small, keen, deeply set beneath heavy brows—flashed from a dull opacity to an alert animation. But in the first and last view of his face it was the mouth that marked the man; the straight, thin lips would close or unclose at their own will, not at another's—the line of the mouth, like the line of the hard, square ...

... possesses the double signification of ray of light and radius of a circle, he avoids its use in the latter sense and speaks always of the semi-diameter, not of the radius. His speculations as to the ether, his suggestive views of the structure of crystalline bodies, and his explanation of opacity, slight as they are, will possibly surprise the reader by their seeming modernness. And none can read his investigation of the phenomena found in Iceland spar without marvelling ...
