The external features of the seal are shown in Figure 3. Dimensions are such that stoppers can be changed without dismantling the seal. The projection (G), on which the bored stopper is placed, is tapered (not shown in the diagram). An absolutely moisture-proof and airtight seal is obtained by applying a drop of Insolac to the upper junction of ( C ) and (A). The shaft (A) and the parts (B), (0,and (D) rotate as a unit. When the desired position is reached (determined by the size of the flask used) the set-screw (B) maintains the adjustment. 1931.īy forang (C) into (D) and boring (() so that and (D) as a unit can just he slipped up and down the stirrer-shaft ( A ). * See m y article "The triumph of education in Spain," U. That is another and longer story.* But this Congress, in charge of the men who have been benefited by the ideals of the Junta fiara Ampliacibn de 10s Estudios Ciatificos, is the concrete evidence of the worth of those ideals. I t is impossible to tell all that has been done for education here by the Junta. Elementary schools, residenaas, or dormitories where the social and intellectual life is developed and encouraged, have been established for both men and women of the Central University. These young men later became the professors in the University of Madrid and in the institutes and universities all over Spain. The committee's work did not end here, for, when these young men returned, trained in foreign ways, with their eyes opened to their opportunity, the committee provided libraries and lahoratories in which they could carry on their research. This end young men who had successfully finished their university careers, were sent abroad to study-to Paris, to Germany, to England.

To reduce vibration two bearing surfaces (E) and ( F ) (Figure 21, which just allow free turning of the stirring-shaft ( A ), are fastened to the body of the seal. For this purpose it was satisfactory but for use at sustained high speeds the seal described in this article (Figures 2 and 3) has been found more satisfactory. 22) was recently described by the author.' This seal (Figure 1) was intended for use with diierent sizes of glass, steel, or brass stimngrods and at relatively low speeds. MERCURY seal made from stainless steel (Allegheny No. ROGERS Rensseker Polytechnic Institute, Troy, New This is a government committee organized more than thirty years ago to improve university education. That there is change is largely due to the wnstant effort, pressure, and initiative of the Junta para Ampliacidn de 10s Estudios Cient&os. Spaniards have been in no sense unaware of the existence of these potential riches, hut they have lacked initiative in the past, and the mines have generally been in the hands of foreigners. From early Roman times many of the mines have been worked.

Mercury, zinc, galena, manganese, phosphate, and potash deposits of extraordinary abundance are only a few of the mineral deposits. Its mines of pyrite are the richest in the world, having yielded during the past year 1,831,000 tons for export. There were a goodly number of these who were esteemed worthy of such honor. In the plans drawn up by the International Committee last summer, conspicuous place was given on the program to young men. Come, spoke of the inspiration to Spanish chemists that would undoubtedly result from this Congress.
