E. E. THUM, * Salt Lake City, Utah (Written discussion ?).-Dr. Fulton's paper sheds a great deal of light upon questions which have perplexed many who have studied the metallurgy of zinc, and have fruitlessly brought forth several hypotheses and reams of discussion. It would be a bright day if others would follow Dr. Fulton's example, for, as a

QUANTITATIVE appraisal of the chances of finding various tonnages and grades of ore clarifies any exploratory development proposal. Ways are discussed of appraising chances in conformance with probability principles, and graphs are suggested to show tonnages, grades and the corresponding judged expectancies.

The adoption of the regenerative principle for burning fire-bricks, pottery, etc., has been delayed beyond what would naturally have been expected, because there bas been until recently little necessity for high heat in burning such material. But the introduction of pro-

R. L. Fleischer (Department of Metallurgy, Massachusetts Institute of Technology)— The authors have presented valuable observations of oehavior of aluminum at intermediate and high temperatures. I should like to consider their interpretation of the appearance of cross slip plane traces in sample B-3 as partly due to "bending of the crystal due to grip constraint." Because bending moments might be set

Through the remainder of this century, world consumption of fluorine per ton of primary aluminum produced will continue to be substantially reduced. Growth of the primary industry will offset some of the unit consumption, but demand for new fluorine sources will decline sharply. Continued application of dry fume scrubbing system will be the most significant factor in reducing demand.

Lithium raw materials usable with present technology consist of pegmatite ore and shallow evaporite brine. Deposits of these materials occur in many parts of the world. Those advantageously located supply the present lithium industry. Less favorably located deposits will come into production as markets expand and present sources are depleted. In this discussion, materials listed as reserves include fully explored and partly explored deposits. For those closely drilled and assayed, the data provide measurements rather than estimates, and such reserve tonnages are "proved." For deposits partly explored, the data support reserve estimates of "probable" tonnages. Materials lacking exploratory data are classed as resources, and their "possible" tonnages are inferred mostly from indirect evidence and are essentially objectives for exploration. All figures for pegmatite ore apply to total materials in the ground.

IN an effort to distinguish experimentally between the radically different limits of two-liquid im-miscibility reported for the Cu-Pb system by Borne-inann and Wagenmann and by Briesemeister (see Fig. I), it was found that the high temperature homogeneous liquid containing between 41 and 93 pct Pb could not be frozen without separation into two liquids with the fastest cooling technique that could be devised. Thus, the two-phase state could not be distinguished with certainty from the one-phase state by the examination of quenched samples. To overcome this obstacle the following method for detecting the presence of an interface between two immiscible conducting liquids at temperature was developed. Measurements made by the new method substantiate the Briesemeister diagram in its general form. The method consists essentially in the measure-

Fundamentals of drying and the equipment used are reviewed. Dryers employed in the mineral industry include rotary dryers, fluid bed dryers, spray dryers, hearth dryers and rotary tray dryers. Concentrate characteristics, corresponding problems and handling methods are likewise discussed. Important factors include weighing and sampling, moisture content, market timetables, transportation availability and climatic conditions.

Early data about the amounts of coal used in making coke, and even of the first oven plants are meager. Table 84 shows the data about beehive ovens from 1841 to 1940, inclusive, and Table 85 shows the data about byproduct ovens from 1895 to 1940, inclusive.
