Now, volatilisation is the most cooling process of nature, by reason of the quantity of heat which is directly converted from the sensible to the latent state.

Some tests made at Woolwich Arsenal with Delta metal bars produced by extrusion showed a tensile strength of 48 tons per square inch with 32*5 per cent, elongation on 2 inches, as against 38 tons per square inch tensile strength and 20 per cent, elongation of rolled bars of the same metal.
Էջ 196 - ... attendants. The weight of hull is, through rational construction and reduction of the scantlings, lessened as much as the strains will permit, in some cases even in excess of a sufficient margin of safety.
