Seite 34 - Resolved, That the thanks of the Society, be presented to the Hon. SA Douglass, for his eloquent and practical address, and that he be requested to furnish a copy of the same for publication in the Transactions of the Society.
Seite 271 - ... austere, often making the lips sore when much eaten. The Isabella and Catawba, on the contrary, are very sweet and agreeable. But the best of all the varieties is the white-fruited, which does not differ in the leaf from the first described, but the racemes are large, long and dense, the berries oval, white or green, with a slight coppery tinge on the side exposed to the sun.
Seite 197 - That a copy of these resolutions be forthwith transmitted by the secretary of the senate to the president of the senate of the United States and to the speaker of the house of representatives of the United States; a copy hereof to each member of congress from the State of California, and a.
Seite 120 - The original substance does not dissolve in alcohol or ether, but in the latter menstruum is covered on the surface with a white coating. In warm dilute hydrochloric acid it is slightly attacked, but not completely dissolved. Tested for nitrogen by Lassaigne's method, by fusion with sodium and obtaining the precipitate of prussian blue, it indicated the presence of considerable quantities of that element. As the body appears to be composed of at least three substances, and the quantity at my disposal...
Seite 307 - The specimen in the collection of the Academy was known to carry off from one farm, in the space of a month, not less than twenty-seven individuals of various kinds of poultry before it was shot.
Seite 120 - ... supposed by some, and which young, in the case of bees, are fed by pollen. Perhaps the accumulation of honey in the ant is the result of a disease like diabetes, though it would seem improbable that it should be a disease so widely diffused. The examination of compounds occurring in the lower animals, which are also the result of the decomposition of amylaceous and albuminous substances, and a comparison of these compounds with the animal's food, has been much neglected by chemists. Yet it would...
Seite 121 - ... requires much nitrogen, lives on highly nitrogenized food), it seems as incredible that bees should be supported entirely by honey as that man should be by starch only. A careful examination of the relation between food and its transformation in the bodies of such animals would no doubt throw great light upon mooted points in physiology ; and the many differences in the nature of the products, which could no doubt be reconciled with the laws of chemistry, would in themselves afford one of the...
Seite 13 - A Notice of the Origin, Progress, and Present Condition of the Academy of Natural Sciences of Philadelphia.
Seite 120 - ... ant ; these acids and other products of decomposition of the three radicals being besides found in other animals and in plants, and some in a diseased state of plant or animal. If it be desirable to study that mysterious force, the vital, how can it be done but by its effects, for which nature must be crossexamined in her every form? This is the more important, as we find vitality to determine the resolution of the same food into different products in different animals, as may be required for...
