Pagina 177 - USA, read a paper on this subject, of which the following is an abstract : — " Cast iron — the raw material from which the malleable metal is made — may be formulated approximately as follows : — Silicon (Si), 5 to 3 per cent. Phosphorus (P), 05 to 2 per cent. Manganese (Mn) , 0 to 20 per cent. Sulphur (S), 25 to 2 per cent. Carbon (C), 2 to 5 per cent. Iron (Fe), 90 to 9G.5 per cent.
Pagina 263 - There can be no reason, then, for doubting that, among insects, contagious and infectious diseases, of great malignity, are caused by minute organisms which are produced from preexisting germs, or by Homogenesis ; and there is no reason, that I know of, for believing that what happens in insects may not take place in the highest animals.

Pagina 129 - on partially liquefying carbonic acid by pressure alone, and gradually raising at the same time the temperature to 88° Fahrenheit, the surface of demarcation between the liquid and the gas became fainter, lost its curvature, and at last disappeared. The space was then occupied by a homogeneous fluid, which exhibited, when the pressure was suddenly diminished or the temperature slightly lowered, a peculiar appearance of moving or flickering strisa throughout its entire mass.
