What a bucketful of corruption was that, a mixture of sap and rainwater that had rotted, and smelled to heaven. Mice and birds and insects had been drowned in it, and added to its unsavory character. It was a bit of Nature cut off from the vitalizing and purifying chem- istry of the whole.
Lenglet du Fresnoy, in his "History of the Hermetic Philosophy," says, "Most of them pretended that Shem, or Chem, the son of Noah, was an adept in the art, and thought it highly probable that the words chemistry and alchymy were both derived from his name." Others say, the art was derived from the Egyptians, amongst whom it was first founded by Hermes Trismegistus.
After that came the statues of Alexander and Ptolemy Soter crowned with gold and ivy: by the side of Ptolemy stood the statues of Virtue, of the god Chem, and of the city of Corinth; and he was followed by female statues of the conquered cities of Ionia, Greece, Asia Minor, and Persia; and the statues of other gods.
What has so far been secured by them it must now be our task to extricate from more doubtful surroundings and place in due order before our readers. Naturf. Frederick Chambers. See also Phil. Phil.

I may also, in the last instance, mention that I have found the above methods of electro-dissolution peculiarly adapted for the preparation of unstable compounds such as stannic nitrate, potassic ferrate, ferric acetate, which are decomposed on the application of heat, and in some instances have succeeded by the following means of crystallizing the resulting compound obtained.

While he talked, Ishie had been busy inserting the carefully machined piece of quartz plate that Chernov had brought, into a conglomeration of glassware that looked like a refugee from the chem lab, and flipped a switch that caused a glowing coil inside a pyrex boiler to heat a small quantity of water, which must escape through the carefully machined capillary holes in the plate he had just installed.
The rider should also be compared with a 5 or 10-milligram weight. In an instructional laboratory appreciable errors should be reported to the instructor in charge for his consideration. When the highest accuracy is desired, the weights may be calibrated and corrections applied. A calibration procedure is described in a paper by T.W. Richards, !J. Am. Chem.
That's what set Celia and Sallie by the ears. Them foolish gals has got it in their heads that they air jest cut out for movin' picter actresses. They wanter go off ter the city an' git jobs in one o' chem there studios! Peleg says he'll spank his gal, big as she is, if she don't stop sich foolish talk. I reckon Celia won't go fur without Sallie."
He looked puzzled, but lifted his hat as she hurried past him, wiping the tears from her face with her free hand. A boy called from across the street an instant later. "Oh, Hugh, I'm coming over for some help on that chem. ex. to-night." "All right," came the answer from "The Unknown," and mixed with Elizabeth's mortifying confusion was a quick thrill at knowing his name. "Hugh!"
In this case the carbon electrode need not be very thick, and can be flat or of tubular form. In the former case it must have a large volume, and the massive cylindrical form is recommended. The zinc electrode must be kept covered deeply with potash. The cells must have free access of air, and the potash must be replaced as soon as it is exhausted. Chem. Zeit.
