The graphic representation of this relationship is shown infig. 4, curve A, an ordinate of 1° C. being taken equal to anabscissa of 1 per cent, of nitre. The curve, after dipping to thecryohydrate, rises through 0° C. and reaches the 100 per cent,at 320° C. Perhaps curve B shows the relationship is traced from columns II. and III. It is asymptotic tothe temperature-line 320° C, and shows how fused nitre andfused ice are miscible with one another in all proportions. and Attached 4. 115. 116 Frederick Guthrie on Salt-Solutions § 253. Boiling-Points of Solutions of Nitre.—To determinethe boiling-points of solutions of nitre of various strengths,40 grams, which were in the later experiments made up to100 grams, were placed in a clean tin vessel havinga narrowneck, together with a thermometer and an indefinite amount ofwater. The whole was supported in a hot-air chamber so thatthe neck only of the tin vessel projected. An arrangementwas also made for blowing hot air through the upper part ofthe vessel. By this arrangement it was hoped that theamount of water condensed in the vessel above the liquidwould be inconsiderable. The liquid was boiled until acertain temperature was reached. The vessel was then re-moved, partially cooled, and weighed. This was done at everyhalf-degree. Jn the table the temperatures are deduced atwhich boiling occurs in strengths rising 5 per cent, from 20per cent.
