DEEP ARTESIAN WELL.

The sinking of the deep artesian well Buda Pesth, Hungary, i 3 now completed; the works were commenced as far back as 1868, and during their progress many interesting facts relating to geology and under ground temperature have been brought ic light. The total depth is 3200 feet, and the temperature of the water it yields is nearly 165 deg. Pahr. The temperature of the -mud brought up by the borer was taken every day, and was found to increase rapidly, in spite of the loss of heat during its ascent, down to a depth of 2300 to 2700 feet. Beyond this point the increase was not ao marked. At a depth of 3000 feet the temperature was 177 deg. Fahr., giving an average increase of 1 for every 23 feet •bored. Water first commenced to well up at a depth of 3070 feet; here its temperature was 110 deg. Fahr , and from this point onward it rapidly increased both in quantity and temperature. Thus, at 3092 feet, its temperature had already risen to 150 deg. Fahr., and the yield ia twenty-four hours from 9500 to 44.000 gallons. Finally, when the boring had reached 3200 feet, at which point it was stopped, the temperature of the water, as it burst from the orifice of the tube, was 165 deg. Fahr., and the volumetric yield 272 000 gallons in the 24 hours. This yield was afterwards reduced to 167,200 gallons, in consequence of the bore being lined with wooden tubes, which re duced its diameter. The water obtained disengages carbonic acid in abundance, and also contains nitrogen and a little sulphureted (hydrogen, and 80 grains per gallon of fixed matters, chiefly sulphates and carbonates of potash, soda, lime, and magnesia.
