RESULTS ## OF THE EXPERIMENTS. In all the experiments except H, I, Jand h, tile cut-off was fixed, so that the measure of expansion with which the ste'ml was used did not vary during each experiment. In experiments H, I, J and 1(, the cut-off was variable by the action of the governor, but the uu

Experiments made at the New York navy ya

Experiments made at the New York navy yard, to determine the relative economic efficiency, in proportion of weight of steam used to weight of water lifted, of a reciprocating-pulvp, a rotary-pump, and a steam siphon-pump, all three being auxiliary steam-pumps for vessels, and raising water to the same height

The following experiments were made under the direction of the writer at the New York Navy Yard during the months of March and April, 1867, to ascertain the weight of water lifted through a given height per pound weight of steam expended, by means of a reciprocating-pump, a rotarypump, and a steam s

Phytochemical terminology*1*Section on H

Phytochemical terminology*1*Section on Historical Pharmacy, A. Ph. A., Miami meeting, 1931.1An account of the development of phytochemical terminology would, no doubt, afford interesting reading. Those who are interested in this subject may read to advantage Runge’s attempt, made in 1820, and based on the dualistic chemistry of oxygen of that period. (Neueste Phytochemische Entdeckungen zur Begruendung einer wissenschaftlichen Phytochemie: Critische Bemerkungen zieber die jetzt herschende Namenmacherey in der Phytochemie, Chap. 4.) It reveals in striking manner the danger of forcing the growth of a language, even if the underlying principles are thought to be highly scientific. Should the present study develop far enough, the writer may, at some future date, attempt an account of this sort.
