Applicants for prizes should send drawings or mo-dels, if necessary, as also estimates of cost. Prizeswill be received up to August 1, 1896.

A year or two ago attention was called to the pre-diction of an eminent authority that we were enteringupon a period of scientific activity that would far tran-scend any previous experience. The most indifferentobserver cannot fail to be amazed at the manner inwhich this prophecy is being fulfilled. Chemists areastonished to find that the long familiar atmospherecontains a large proportion of a substance hithertounknown—the strange and Inert argon ; and helium,so long known in the spectrum of the sun, is discover-ed as a terrestrial element. With the liquefaction ofair and hydrogen we are introduced to a new chemistryof cold. Thedevelopmentofthe electric furnace bringsgreat possibilities in the reduction of certain metals,and among its remarkable products yields calcium car-bide, the source of acetylene, which is the first hydro-carbon to be produced artificially on a large scale, anda revolutionar
