The army of Vitel'lius, which consisted of seventy thousand men, was commanded by his generals Va'lens and Cecin'na, he himself remaining in Gaul, in order to bring up the rest of his forces.

... you must think of the eye as a lens, but one made up of cells, of tissues. It can know inflammation. As a result of many inflammations there is what we call an exudation—a liquid passes from the tissues. This may be thin or serum-like, or it may be heavier, something like granulations. The tissues are weak—they exude something ...

... fraught with numerous perils for the travelling hosts. Attracted and blinded by the torches of lighthouses, multitudes of birds are annually killed by striking against lighthouse towers in thick, foggy weather. The keeper of the Cape Hatteras light once showed me a chipped place in the lens which he said had been made by the bill of a great white Gannet which one thick night crashed through the outer protecting glass of the lighthouse lamp. As many as seven hundred birds in one month have killed themselves by flying against the Bartholdi Statue of Liberty in New York Harbour. As its ...

... It is not operated by light, at least not by light alone. A certain temperature must be attained, and that temperature suffices in complete darkness. Nevertheless, I find that on exposing to a very concentrated spectrum (collected by a lens of short focus) a slip of paper prepared as above (that is to say, by washing with the mixed solutions, exposure to sunshine, washing and discharging the uniform blue color so induced, as in the last article), its whiteness is changed to a brown over the ...

... how magicians, by the use of Galileo's Tube, could show seven stars where there was only one; and he even made such a tube of his own and called the priests together to look through it. He painted stars on the glass, and had men look at the heavens. He even stuck a louse on the lens and located the beast in the heavens, for the benefit of a doubting Cardinal. It was all a joke, but at the time no sober, sincere man of Science could argue him down. He owned "bum" telescopes that proved all kinds of things, to the great amusement of the ...

The palatine teeth are still more minute, and the band is four or five deep. The teeth, when examined with a lens, appear to be very acute and in nowise spherical. The pharyngeal teeth are subulate and acute, and of unequal heights. There seems to be only one inferior pharyngeal bone below; but without dissection this could not be clearly made out. The outer branchial ...

... and servant. Consequently there was no one to devise the practical apparatus by which alone profound and ever-increasing knowledge of natural operations is possible. The mechanical inventiveness of the Greeks was slight, and hence they never came upon the lens; they had no microscope to reveal the minute, no telescope to attract the remote; they never devised a mechanical timepiece, a thermometer, nor a barometer, to say nothing of cameras and spectroscopes. Archimedes, it is reported, disdained ...

Moreover, at ordinary temperatures benzene is a liquid, for it boils at 81 deg.

Usually in this condition the curds look as if they had been punctured with a pin, and are known as "pin holey" curds. Where the gas holes are larger, they are known ...
