One gramme of clean mastic is dissolved in eighty-seven grammes of absolute alcohol, and the transparent solution is allowed to drop into a beaker containing clear water briskly stirred. An exceedingly fine precipitate is thus formed, which declares its presence by its action upon light.
A gas generator supplying a gas motor burning Swansea anthracite and Noeux coke, medium quality, will consume 516 grammes of anthracite and 90 of coke to produce 2,370 liters of gas giving 1,487 heat units per cubic meter. Of the 3,524 heat units furnished to the motor by the 2,370 liters of gas, the motor will convert 18 per cent. into disposable mechanical work.
Alas! the brave fellow was destined to a cruel end, but I will return to that later. The sufferings endured through the siege began to have their effect on the morale of the Parisians. Bread had just been rationed out: there were to be 300 grammes for adults and 150 grammes for children. A silent fury took possession of the people at this news. Women were the most courageous, the men were excited.
By the action of nitric acid in presence of mercury, a semi-solid mass is produced of a much deeper color than in the preceding cases. A portion of the oil remains in the liquid state, as is usually the case with drying oils. Free Acidity. By the method indicated, it was found that 100 grammes of oil required 0.39 grammes caustic potash to neutralize the acid occurring in a free state.
If a stone of the weight of a hundred grammes be lifted ten meters high and then flung free so that it should remain hanging in a self-contained condition and in a state of rest, you would have to appeal to a public of sucking infants to declare that the existing condition of that body represents no mechanical labor and that its removal from its earlier condition has no measure in mechanical work.
After several days' rain during the summer, a quantity of the water was caught, evaporated, and the residue dried. Its characteristics were similar to those above mentioned. By an experiment instituted in water under conditions similar to the first mentioned, the dry brown substance weighed 71 grammes. It possessed the same characteristics.
As a gramme equals 15.4 grains, and a cubic inch of water contains 252.4 grains, this is equivalent to 62 cubic inches of water; so that as brain is heavier than water, we are perfectly safe against erring on the side of diminution in taking this as the smallest capacity of any adult male human brain. The brains of five children, four years old, weighed between 1275 and 992 grammes.
As it was of interest to see whether this increase in intensity was not due to a greater consumption of oil, a determination was made of the quantity of the latter consumed per hour. The Gagneau lamp, with the old chimney, burned 62.25 grammes per hour, and with the Bayle 63 grammes in the same length of time.
They may be observed budding, at least many of them, and there can be no doubt that those which do not bud still continue to live; life has other ways of manifesting itself besides development and cell-proliferation. which became, after fermentation, we repeat, without taking into account the matters which the sugared water gained from the yeast: grammes. grains. 2.486 Increase 0.173 = 2.65
In this way from 100 c.c. of the oil, about 13 grammes of soot of a very good quality were obtained. Soot or lampblack is a very important material in Japan for making inks, paints, etc. If the manufacture of lampblack from the cheap camphor oil is conducted on a large scale, it would no doubt be profitable.
