The Bloede and the Hoffmann Scholarships of the Chemists’ Club Applications for the Bloede and the Hoffmann Scholarships of the Chemists’ Club of New York should be submitted by the middle of June. The object of these scholarships is to assist deserving young men t o obtain an education in the field of industrial chemistry or chemical engineering. The scholarships are open without restriction as to residence, and may be effective at any institution in the United States, which may be designated or approved by the Scholarships Committee. Applicants must have completed a satisfactory high school training, involving substantial work in elementary chemistry, physics, and mathematics, and present a certificate showing that they have passed the examination requirements of the College Entrance Examination Board or its equivalent. Preference will be given to candidates who have had additional academic work, especially in subjects which will form a suitable groundwork for the more advanced study of applied chemistry and chemical engineering.
Vol. 13, S o . 5
Applications should be sent to Mr. F. G. Zinsser, Hastings-onHudson, New York.
Centrifugal Method for Determining Potash Editor of the Journal of Industrial and Engineering Chemistry: Since submitting my article on a “Centrifugal Method for Determining Potash” [THISJOURNAL, 13 (1921). 2271 I have learned that others have worked along this same line, among them being Mr. H. P. Bassett, of Meigs, Bassett & Slaughter, Inc. To him and all others to whom credit is due, due credit is here given. HOLLY SUGAR CORPORATION ELMERSHERRILL HUNTINGTON BEACH, CALIFORNIA
