    The president of the French Academy of Sciences, in a recent eulogy of Count Hilaire de Chardonnet, stated that no one was more firmly devoted to the academy and no one more attached to its traditions. His high ideals, his kindly manner, and his strong friendship were appreciated and re- spected by all who came in contact with him. His true title

    to scientific glory is being the first to prepare and bring into production a new synthetic silk,

    HE results of the first census of graduate research students in chemistry,2 undertaken last year by the T Division of Chemistry and Chemical Technology of

    the Sational Research Council, appeared to be of sufficient interest to warrant the repetition of the work this year. In addition to the reasons given by Dr. Zanetti for making such a detailed study of the research work carried out by candidateq for advanced degrees, the census will be of value in indicating to the officers of the Division the results of the efforts made to encourage and develop research in those fields to which the Division is giving particular attention. The activity of the Committee on Colloids during the last few years is reflected in the large number of researches in this division of chemistry. During the past year aliphatic chem-

    htry, as exemplified in fundamental research in petroleum, has been emphasized. I t will be of interest to note the in- creased activity in this field as the result of the work of the recently formed Committee on the Chemistry of Petroleuni. The Division a t its last annual meeting voted to hare the next census taken in 1927.

    In order to make comparison possible, following each nuin- her in the general account of the results the corresponding number for the 1924 census is given; 1924 figures are also given in Table 11.

    In collecting the information this year cards were sent only to the institutions that responded last year, with the excep- tion of twelve institutions. Of these all but eleven replied. Twenty-four institutions m-hich reported student> last year reported no students this year.

    The number of universities, colleges, and schools of engi- neering and agriculture furnishing data was 121 (139); the number of medical schools was 24 (32) , and the number of schools of pharmacy was 10 (13).

    The total number of graduate research students in chemis- try reported was 1763 (1700) distributed in various fields, as shown in Table I. Of these, 970 (563), or 55 (52) per cent, were reported by 13 (12) universities and colleges, including all their departments; 1234 (1193), or 69 (70) per cent, were reported by 25 (25) universities and colleges; 1412 (1357), or 80 (80) per cent, were reported by 40 (40) unirersi- ties and colleges.

    In the group of 13 (12) universities and colleges which re- ported 55 (52) per cent of the total number, the highest number reported by any individual institution was 137 (122), followed by 101 (115) for the next competitor; the third and

    fourth reported 99 (93) and 89 (91), respectively. The lowest number of research students reported by any one institution in that group was 51 (47).

    The distribution of these 1763 (1700) students among the various fields of research is of interest. The physicochemical group (general, colloid, catalysis, subatomic, electrochemistry, photochemistry) appears to attract more students than any other; 544 (460) research students are working in this group. Organic chemistry comes next with 430 (420) research stu- dents. It is interesting to note that 44 (41) per cent of these are working in the aliphatic series. The medical group (physiological, pharmacological, pharmaceutical, nutrition, and bacteriological) is unexpectedly large, 333 (276) research students being a t work in those fields. Industrial and engi- neering chemistry comes fourth with 184 (203) research stu- dents, and inorganic chemistry fifth with 86 (101) workers.

    HE specifications given below are intended to Serve for re-

    tests are based On published work and On the experience Of members of the committee and others in the examination Of reagent chemicals on the market. Suggestions for improvement of the specifications will be welcomed by the committee.

    some^ like the strength of acids, are absolute requirements, regardless Of the method of testing; others are merely that the chemical shall pass the test given, and the suggested limit may show only approximately the quantity of the impurity in question.

    In all the directions the acids and ammonium hydroxide re-

    Solutions of the sample must be filtered for tests in which insoluble material

The liquids should be equally clear and free from suspended mat- ter and on looking across the columns by transmitted light there should be no apparent difference in color between the two liquids.

    Assay-Tare a small glass-stoppered Erlenmeyer Bask containing 15 cc. of water. Quickly introduce about 3cc. of the acid, stopper, and weigh.

    Nonaolafile Matter-Evaporate S5 cc. of the acid to dryness in platinum afteraddition of a drop of sulfuric acid, ignite at cherry redness for 5 minutes, cool, and weigh.
