H. M. BOYLSTON, Cambridge, Mass.-It might be asked, since this test is so simple, why it was not discovered before. It seems to me the explanation is that when we have used the sodium picrate solution, it has .generally been on a very, high-carbon or hypereutectoid steel; to detect . the presence of free cementite, and when we have looked for sulphides, it

Methods are given for estimating heat flows into mining excavations of various types, with an example to illustrate how the refrigeration requirements are then determined after allowing for the cooling effects of the ventilation air.

THE CHAIRMAN (WALTER DOUGLAS, New York, N. Y.).--I presume, gentlemen, that Mr. Howard's experience with the Great Falls basic-lined converter has been as regards the tonnage produced from a single lining, perhaps, a world's record. About 6 months ago Mr. Howard shut down and tore out what was left of the first basic-lining which was installed at the Old Dominion, the lining having produced something over 70,000,000 lb. of copper. This was due probably not only to the very excellent grade of the matte which was produced by the smelter there,

The minimum sulphur level which can be attained during fluid bed roasting of zinc sulfide concentrates is largely determined by the residual sulfates of calcium, magnesium, and zinc. The fractional conversion of these elements to their respective sulfates is derived from semi- empirical relationships, and multiple regression analysis is used to fit the relationships to experimental data from a commercial fluidized bed roaster. The resulting equation shows that the calcine leaving the roaster contains almost no zinc sulfate, nearly all of the calcium is present as calcium sulfate, and the amount of magnesium sulfate formed is primarily dependent upon the roaster temperatures.

THEORETICAL analysis by Wechsler, Lieberman and Read of the crystallography of martensite formation has shown that the requirement for the existence of a macroscopically undistorted plane between austenite and martensite permits a calculation of the indices of the habit plane of the marten-
