It is not unusual to see infants weighing eight or nine pounds at birth, but babies of more than ten pounds are rare, and the fabulous, though not infrequent, reports of fifteen and twenty-pound infants are probably not based upon actual weighings, but upon the impression of someone who has merely seen the child or perhaps guessed the weight from lifting it.
It is not necessary that such a set should be strictly exact in comparison with the absolute standard of weight, provided they are relatively correct among themselves, and provided the same set of weights is used in all weighings made during a given analysis. The analyst should assure himself that the weights in a set previously unfamiliar to him are relatively correct by a few simple tests.
For the sake of simplicity, he had assumed circular orbits and calculated their approximate orbital velocities from their distance from the sun. He had determined the mass of the sun from direct weighings aboard their ship. He soon had a fair diagram of the system constructed mathematically, and experimental observation showed it to be a very close approximation.
Both weighings should be accurate to a grain. This result we call B. The specific gravity is found by subtracting B from A, and dividing A by the remainder.
In order to give our dairy the proper credit, we would kindly ask what you consider a fair price for the manure of a cow for one year. Also what would the manure from a horse for one year be worth? A compilation of a considerable number of weighings, analyses and valuations in Europe, cited by Prof.
When designing the measuring apparatus, the object should be to minimize, within economical and practical range, the total number of weighings or measurements necessary. Consequently, no strict time of interval between individual weighings or measurements can be given in this case. It may be said, however, that it is not desirable to take these at anything less than five-minute intervals.
Finally set the crucible upright in the triangle, cover it, and heat at the full temperature of a blast lamp or other high temperature burner. Repeat the strong heating until the weight is constant within 0.0003 gram. On this account the weighings must be promptly completed after removal from the desiccator.
And the woman, leaning against the bunk, raging and impotent, watched herself weighed out in yellow dust and nuggets in the scales erected on the grub-box. The scales were small, making necessary many weighings, and Messner with precise care verified each weighing. "There's too much silver in it," he remarked as he tied up the gold-sack. "I don't think it will run quite sixteen to the ounce.
Darwin's careful weighings and measurements, that, though little used parts in domestic animals get reduced in weight and somewhat in size, yet that they show no inclination to become truly "rudimentary structures." Accordingly he asserts that such rudimentary parts are formed "suddenly, by arrest of development" in domesticated animals, but in wild animals slowly.
Lavoisier concluded that to calcine tin is to cause it to combine with a portion of the air wherein it is calcined. The weighings he made showed that about one-fifth of the whole weight of air in the closed flask wherein he calcined tin had disappeared during the operation.
