...line of sea investigation an 800 pound sounding tube is plunged into the ocean floor, in order to bring to the surface a core of mud three or more feet in length...
Quite often the tube must be dropped 2,000 to 3,000 fathoms in order to reach the bottom. Because of the slow accumulation of sediment in midocean this tiny core of mud may represent thousands or even hundreds of thousands of years. Scientific interest lies in measuring the thickness of these stratifications of mud cores in order to determine former changes in depth and climate. Telegraph companies are particularly interested in this work, because they wish to learn how fast matter accumulates on the sea bottom in order to avoid laying cables in regions where the rate of deposition...
...Hans Fischer achieved his first international fame two years ago. After 17 years of quiet research in his laboratory at Munich, he announced that he had succeeded in synthesizing hematin, the red iron core which carries oxygen into the blood (TIME, Jan. 7, 1929). He used pyrrol, a constituent of the common cure-all known as bone oil, subjected the colorless liquid to a complicated chemical treatment to obtain his results. The synthetic product he called hematine. Or ganic chemists are now experimenting with the substance, using it upon animals to de termine how doctors may employ it to cure...
...what Sir John beamingly called a "novel plan," the report was split into two sections: 1) "History" and 2) "Recommendations" of which only the former was issued last week. Although a "best seller" and Conservative to the core, it drew from the arch-Conservative Morning. Post a comment which rather let the cat out of the bag: "This survey is so carefully balanced and so judicially vague that it is difficult to see to what it leads...
...mutual understanding between secondary school and college. In my opinion this is a concern of departmental faculties as much as of headmasters, deans, and chairmen of committees on admission. These closing years of the secondary period should afford opportunity for concentration of the individual's courses about a core-curriculum reflecting his particular needs and aspiration. This does not mean free election nor radical restriction of the total number of courses. A reduction of one or possibly of two courses out of the fifteen carried in some schools (several even now have no more than thirteen) would afford sufficient hours...
