Страница 50 - Observations on the Means of preserving' the Health of Soldiers and Sailors ; and on the Duties of the Medical Department of the Army and Navy: -with Remarks on Hospitals and their Internal Arrangement. By Edward Cutbush, MD of the Navy of the United
Страница 93 - when either of them is brought into an electrical state opposite to its natural one. In the synthesis, on the contrary, the natural energies or attractions come in equilibrium with each other; and when these are in a low state at common temperatures, a slow combination is effected
Страница 84 - that the repellent and attractive energies are communicated from one particle to another particle of the same kind, so as to establish a conducting chain in the fluid, and that the locomotion takes place in consequence. In
Страница 99 - do the metallic properties of AMMONIUM depend ? Are hydrogen and nitrogen both metals in the aeriform state, at the usual temperatures of the atmosphere, bodies of the same character, as zinc and quicksilver would be in the heat of ignition ? Or are these gases, in their common form, oxides, which become metallized by deoxidation ? Or are
Страница 119 - In every part of the earth where man exists, the power of climate operates with decisive influence upon his condition and character. In those countries which approach near to the extremes of heat and cold, this influence is so conspicuous as to strike every
Страница 86 - In the simplest case of electrical action, the alkali which receives electricity from the metal -would necessarily, on being separated from it, appear positive, whilst the acid, under similar circumstances, -would be negative ; and these bodies having respectively, with regard to the metals, that which may be called a positive and
Страница 89 - for solution of zinc is formed, and the hydrogen disengaged. The negative energy of the copper, and the positive energy of the zinc, are consequently again exerted, enfeebled only by the opposing energy of the soda in contact with the copper, and the process of electromotion continues, as long as the chemical changes are capable of being carried on.
Страница 89 - capable of combination with the metal, they produce a momentary equilibrium only. The electrical energies of the metals with regard to each other, or the substances dissolved in the water, in the voltaic and other analogous instruments, seem to be the causes that disturb the equilibrium, and the chemical changes the causes that tend to restore the equilibrium
