Joseph H. Stewart of the Division of Industrial and Engineering Chemistry has been named chairman of the Committee on Professional Relations and Status. Such matters as the transferability of employment rights for chemists and chemical engineers who change jobs, employment aids for retired chemists, and a statement of ethics for the chemical profession are some of the matters which have received attention from this committee in the past year. It also acts as an advisory group to members seeking guidance on professional problems. Chemical Education. Chairman of the Committee on Chemical Education is Dr. Ernest I. Becker of the New York Section. Dr. Becker succeeded Dr. Moses Passer last September when Dr. Passer became ACS Educational Secretary. This committee is responsible for the ACS student affiliate program and for developing a comprehensive program of career guidance. It also advises the Council on matters relating to the improvement of chemical education. Albert C. Patterson of the Division of Petroleum Chemistry is chairman for a third year of the Committee on Constitution and Bylaws. The duties of this committee include reviewing the Society's governing documents and initiating such amendments as may be appropriate to meet changing conditions. The committee offers advisory aid to local sections and divisions planning changes in their constitution or bylaws so as to avoid conflicts with ACS policy. The Committee on Local Section Activities is headed again this year by Dr. Leonard V. Sorg of the Kansas City Section. The many areas of ACS activity which affect the local sections are the concern of this committee and, therefore, many of its responsibilities overlap those of other Council committees. Formation of all new sections and territorial changes are first reviewed by this committee. It seeks to assist sections in strengthening their programs and advises them on matters of policy. The committee recommends to the ACS Council the amount of the allotment of members' dues to be returned to the sections. The annual reports of the 165 sections are reviewed by the committee, 60

which also acts as a canvassing committee for the annual ACS Local Section Member Relations and Public Relations Awards. Publications. John S. Ball of the Northeast Oklahoma Section is chairman of the Committee on Publications for a third year. This committee oversees the entire ACS publications program to assure that it meets the needs of the chemical profession. Last spring the committee reported on an extensive study of Chemical Abstracts pricing policies. Much of the committee's work involves close cooperation with the Board of Directors Committee on Publications. Two other major Council committees are elective bodies. Members of the Council Policy Committee and the Committee on Nominations and Elections are selected by vote of the councilors from their membership. The Council Policy Committee, the executive committee of the Council, consists of 12 elected members plus the President-Elect, President, and Executive Secretary of the Society. This committee plans the detailed agenda
for each Council meeting and acts ad interim for the Council on matters requiring immediate attention. President Price is chairman. Nominations and Elections. Dr. George W. Watt of the Central Texas Section heads the Committee on Nominations and Elections again this year. This committee annually solicits proposals from ACS members for nominations for the national offices. It then prepares a slate of nominees for regional directors, director-atlarge, President-Elect, and members of the CPC. The Council chooses the CPC members and the director-atlarge and selects nominees for regional directors and President-Elect, who are then submitted to the ACS membership for election. The Committee on Nominations and Elections supervises all Society elections involving the membership as a whole. Additional information relating to the committees of the Council may be obtained from Bylaw III, Sec. 3, of the Constitution, Bylaws, and Regulations of the American Chemical Society.
NSF Releases Salary Data on Chemists Medians advance over 1962 levels but some changes in makeup of the profession loom The median annual salary of all chemists in 1964 was $11,000, according to data recently released to the ACS by the National Science Foundation (C&EN, Feb. 1, page 15). Based on findings of the National Register of Scientific and Technical Personnel, the median salaries for the three principal degree levels last year were as follows: bachelors, $9900; masters, $10,600; doctors, $13,000. These figures represent increases of $600 to $1000 a year over comparable salaries reported for chemists in 1962. At that time, holders of these degrees reported median salaries of $9000, $10,000, and $12,000, respectively. Part of the increase is due to the fact that 1962 salaries were reported by chemists to the nearest $1000 increment. For 1964, respondents to the National Register were asked to list A staff report of the ACS Office of Professional and Government Relations.
salaries only to the nearest $100. Thus, the most recent figures provided a more accurate picture of the current economic situation in the chemistry profession. Based on data covering some 63,000 chemists and a limited number of chemical engineers, ACS analysis of the early NSF statistics shows that some changes in the composition of the profession may be in the making. For example, in 1962 about 4 1 % of chemists reporting to the Register had the bachelor's degree. By 1964, this figure had risen to 44%. Conversely, the number of doctoral chemists in the U.S. two years ago was 39%, whereas last year fewer than 36% had the Ph.D., D.Sc, M.D., or equivalent. Masters held even at about 19% over the two-year interval. Type of Employer. As in the past, (C&EN, Dec. 30, 1963, page 54), self-employed chemists continue to be the highest paid group in the pro-

fession. Their median annual salary for all degree and experience levels in 1964 was $15,000. The next highest paid group consisted of chemists in industry, with $11,700. At the other end of the scale were chemists working in the military and U.S. Public Health Service, who received only $7000. As with academic degrees, some shifts in employer classification also may be in the offing for chemists. Specifically, an almost even exchange in proportions of personnel seems to have occurred last year between industry and educational institutions. Thus, while industry experienced a 5% drop in the total number of chemists employed, educational institutions picked up a corresponding 5 % . At the close of the year, the two groups accounted for 63.6% and 22.8% of the total chemist population, slightly more than 86% of all those working in the science. No marked changes occurred in any of the other employment classifications commonly used by NSF.
Copies of NSF Bulletin 64-27 reporting salaries of chemists and all other scientists can be obtained for 5 cents each from the Government Printing Office, Washington, D.C. A limited number of free single copies are available from the ACS Office of Professional and Government Relations.
Work Activity. The work activity patterns reported by the ACS in previous years continued with little change for 1964. Chemists in management functions again drew the largest salaries last year, $15,000, irrespective of degree or experience levels. Least well paid, as in the past, were chemistry teachers, whose median annual salary was $8900. As far as distribution of work activity was concerned, the greatest proportion—nearly one half—of chemists

again were involved in research and development. In management, the proportion of chemist administrators dropped slightly from 1962 levels. Fewer than one quarter reported responsibility in this area of activity for 1964. Geographically, the distribution of chemists in 1964 did not vary greatly from the 1962 figures reported by the Society. The Middle Atlantic statesNew York, New Jersey, and Pennsylvania—continued to employ the greatest number of chemists, about 28%. And, as might be expected, New York and New Jersey were the top two states in the population list, just as they were for the 1964 class of graduating chemists and chemical engineers (C&EN, Nov. 9, 1964, page 124). The least populous region of the country comprised the western mountain states, where somewhat less than 3 % of chemists were employed. Later this year, NSF will supply the Society with more comprehensive statistical data collected via the National Register activity in 1964. As in the past, these final data will then be analyzed and reported comprehensively by the Society. Some of the changes noted above may vanish under closer scrutiny. Meanwhile, it appears certain that the continually rising salary pattern for chemists of previous years will be repeated generally for 1964.

consisting of...
L U F T C O N T R O L L E R and LEEDS & N O R T H R U P pH METER For rapid, precise pH titrations, or oxidation-reduction titrations* New type Automatic Buret with push button operated solenoid refill valve
Titrant is delivered at maximum rate until a preset pH value, close to endpoint, is reached. Subsequent delivery is automatically switched to a slower preset rate to prevent overshooting.
This assembly increases both speed and precision of serial titrations made to a preselected pH or oxidation-reduction endpoint. Useful also for rapid adjustment to critical pH value of samples or reaction mixtures. Compensation can be made for mixing lag or for kinetics of non-aqueous reactions by means of a time delay circuit. With the latter control feature in play, completion of titration will not be signaled, and titrant will continue to be added until endpoint persists for a selected time interval. Both titration stages and final endpoint are signaled by colored indicator lamps. Pushbutton switch operates sole noid valve in buret refill line, putting titrator in readiness for next sample. Operation. Mode switch is set to control rising or falling input value, depending upon the characteristics of the titra tion. The pH meter is adjusted to indicate desired endpoint. Control knob A is turned until indicating lamp switches from
red to amber, to set endpoint. Anticipation point, at which buret delivery is to be changed from fast to slow, is set by adjusting pH meter to desired value and turning control knob Β until lamp changes from amber to green. Termination time delay switch has positions for zero, infinite, or adjustable delay. Timer control sets delay from 0 to 57 seconds, to accommodate reaction lag, etc. Pushbutton switch begins the titration and can be used to interrupt operation at any point. During titration, green lamp indicates fast titrant delivery, amber lamp indicates slow delivery phase. Amber and red lamps together indicate apparent endpoint with time delay in effect. Red lamp signals end of operation. Buret is then read and refilled for next titration. 9679-M. Titration Assembly, Automatic, consisting of Luft Controller, L.&N. Model 7401 pH Meter with glass and calomel electrodes, Automatic Buret, porcelain base titration stand with swinging shelf, Variable Speed Stirrer, clamps, holders, connecting cables and line cords, but without beaker or tubing for buret filling.

utilitarian reactions A study of soluble silicate chemistry reveals many interesting and useful properties. This is particularly true of the reactions of sodium and potassium silicates with other compounds. Frequently, different end products can result from the same two reactants, depending on how you vary time, temperature, and concentration. Here are some of these versatile reactions (with pertinent applications)... React a Ca + + salt with Na 2 0:3.22Si0 2 ("N" sodium silicate) and you can get hard, gritty particles, or flake precipitates, or soft, slippery jellies that dry into rigid insoluble masses. {Uses: paper fillers, water-resistant cements, soil solidifiers.) Or you can combine either a sodium silicate or a potassium silicate with salts of Ca, Mg, Al, Cu or Pb and obtain insoluble silicate films or modified forms of the original silicate. If Na 2 Al 2 0 4 and a sodium silicate react, the products can be hard, rocklike gels with a complicated brush-heap type pore structure that is highly absorbent. These gels also possess base-exchange properties. Return the coupon and we will be very glad to send you a data file on the chemical reactions of PQ soluble silicates.
