Southeastern Sections Meet in Atlanta Delegates from 22 ACS local sections discuss programs and problems at two-day conference Delegates from 22 ACS local sections in the Southeast met last month in Atlanta to discuss new ideas for strengthening section programs and to seek out fresh solutions for old prob lems. The intensive two-day confer ence was the fourth of a series spon sored by the ACS Council Committee on Local Section Activities. In the opening session, Dr. George W. Campbell, chairman of the com mittee, set the tone for the subsequent discussions when he told the dele gates, "If the Society is to be more than a publishing house and meeting agency and provide meaningful ser vice to its members, the work must be done at the local section level by local section members." The ACS Speakers Tour Service in the Southeast, formation of topical groups and subsections, and special local section activities for high school teachers and students were among the topics discussed in detail. The meeting agenda also included sessions on long-range planning, local section membership campaigns, im proving the public image of chemists and chemical engineers, and stimula tion of younger ACS members. The final item on the program was an open discussion on specific problems and questions about local section opera tions and national Society policies. Topical Groups. Only two sections in the Southeast have topical groups and only one has subsections. For mation of topical groups should be considered by every section, the dele gates were told, since such groups strengthen the over-all section pro gram and provide an effective means to serve a greater number of mem bers. Furthermore, topical groups usually draw out more of the younger members who are interested in indepth discussions in their fields. Many of the southeastern sections cover a large geographical area. Sub sections, serving focal points of chem ical activity within a section, can best provide for the needs of members in
remote areas of the section territory, it was noted. High School Teachers. Local sec tions can do much to encourage and stimulate science education at the high school level. Specific activities, such as special symposiums for teachers and students, high school teachers' nights, outstanding teacher awards, summer employment assistance, gifts of surplus equipment, scholarships, and radio and television science quizzes were cited for consideration. Nearly every school needs help and information on chemical safety, the conferees were told. Safety posters and films are available for section use and the ACS Committee on Chemical Safety is planning a booklet on safety programs for ACS local sections. Public Relations. Favorable public opinion toward chemistry and chemi cal scientists, essential to the progress of science, can best be promoted at the local level. The delegates were encouraged to improve their communi cation with local editors and reporters, local government, school officials and teachers, and leaders in their respec tive communities. New Members. This year empha sis on the ACS membership recruit ment campaign was shifted from na tional headquarters to local sections. Preliminary indications are that 1966 will be a banner year for new mem berships and enrollments will exceed all previous years. Although mem bership solicitation techniques may vary, it was the consensus that every prospect should be contacted person ally and invited to attend a section meeting in which he would have a particular interest. All ACS sections should make spe cial efforts to consider the interests and meet the needs of the younger ACS members (85% of all members have joined in the past 15 years). Meaningful, short-term projects and community service activities often ap peal to the younger members, but their opinions should also be solicited

by a section's long-range planning committee. Program Planning. The current system of providing tour speakers is working well in most circuits in the Southeast. Nevertheless, the sections were encouraged to experiment with their meeting programs and consider speakers from other sources. Sections should also explore the possibility of holding fewer "speaker" meetings, substituting more symposiums, short courses, or meetings-in-miniature. In the open discussion which concluded the conference, the delegates gave attention to such topics as ACS assistance to retired chemists, local section dues allotments, increasing meeting attendance, and improved regional communication among the southeastern ACS sections. Marshall W. Mead, manager of the ACS Local Section Activities Office, conducted the conference, in cooperation with Dr. Campbell. Two other members of the Local Section Activities Committee, Dr. John W. Brooks and Dr. Paul V. Smith, and four ACS staff members also participated. The next regional conference on local section activities will be held in April near Dallas, Tex., for the southwestern sections.

ACS Comments on Maryland Lab Bills Maryland has joined the growing parade of states considering laws to regulate the activities of clinical laboratories which provide services to physicians. In the main, this push stems from a request made by the Social Security Administration to all states asking them to identify qualified independent laboratories which can be reimbursed under the terms of medicare. Backing up the need for this information, Social Security is now developing its own standards of performance which will aid in the identification of such laboratories. The three Maryland bills are S.J. Res. 9, HB 675, and HB 747. The Senate resolution proposes a thorough study of the licensing of clinical laboratories. HB 675 seeks to empower the State Department of Health with more authority to regulate laboratories. And HB 747, sponsored by the Maryland Association of Bioanalysts, maps out a program for immediate regulation of laboratories operating in the state. 54

on chemicals for fiie retardance C24H43.1CI6.9 FOR FABRICS AND PAINTS CP®-40 (Hooker chlorinated par affin) is useful in compositions for fireproofing and waterproofing heavy fabrics such as duck or canvas. I t also has applications in special, fireretardant paints. Its effectiveness as a fire retardant is due to release of HC1 at high temperatures. CP-40 is a light, honey-colored liquid averaging 4 2 . 5 % chlorine and containing 10 p p p or less iron. I t is soluble in most organic solvents, has a pour point of 0°C and decomposes at the boiling point.

A FULLY CHLORINATED PHTHALIC ANHYDRIDE If you are interested in imparting heat and fire resistance to alkyds, polyesters, plasticizers or similar products, Niagathal® (tetrachlorophthalic anhydride) m a y be just the intermediate for you. I t carries half its weight in stable chlorine. Consequently, it enables you to load as much as 2 2 % by weight of stable chlorine into poly esters containing pigment or fillers. Niagathal has a melting point of 254°-255°C and a boiling point of 371°C. CI

INHERENT FIRE RETARDANCE FOR RESINOUS PRODUCTS Het® Acid, also known as chlorendic acid, is unique among dibasic acids in that it contains over 5 4 % of its weight in stable chlorine. You can use it to make fireretardant resins, plasticizers, lami nates, adhesives, coatings and plastic materials. H e t Acid is not an additive. It combines chemically with the resin to become a n integral part of the formula. Our basic position in chlorine and phosphorus chemistry has helped us develop a substantial reservoir of knowledge in the area of fire-retardant chemicals. Those discussed briefly above are only a few of the m a n y we have to offer.

In a letter to the Speaker of the House of Delegates, Executive Sec retary B. R. Stanerson offered the as sistance of the Society, based on sim ilar experience it has had with this type of legislation in New York and Illinois. Dr. Stanerson also stated that the Society's "present inclination is to favor the concept inherent in SJ. Res. 9, inasmuch as clinical laboratory li censure is a complex and important matter which should be given full study before enacting legislation is contemplated." With the General Assembly due to adjourn by the end of March, passage of any of these lab bills seems prob lematical. During the closing days, though, the Judiciary Committee of the House of Delegates has begun to look favorably at HB 675, sponsored by the Health Department. If adopted, chances are good that the department will use the medicare lab oratory conditions as a model for es tablishing minimum standards of qual ifications. HB 747 looks unacceptable to the House committee. And, at press time, no word was forthcoming on the fate of the Senate resolution.
Cyanamid Division, CAS Set Up Joint Experiment Chemical Abstracts Service and *the Organic Chemicals Division of Amer ican Cyanamid Co. have initiated a computer-based information experi ment designed to store and retrieve whole abstracts of current technical articles and to match these abstracts with keyword profiles of scientistusers. Called Selective Dissemination of Information (SDI) and directed to ward maximum use of CAS's modern computer capability, the system is in tended to supplement the technical reader's exposure to the literature by including journals, and possibly other materials, of a general chemical na ture rather than those pertinent to specific subject areas. This unique approach is aimed at increasing the efficiency and upgrad ing the literature awareness of the lab oratory worker. It also provides the reader with greater coverage through abstract scanning instead of the usual title listing.

est to them," says Dr. J. H. Paden, di rector of research and development of Cyanamid's Organic Chemicals Divi sion. "The SDI program broadens each reader's scope by allowing him to scan whole abstracts of supplementary journals and other basic sources he might not have time to read in detail. User orientation is the key." The joint CAS-Cyanamid experi ment will tie in closely with the SDI program which has been under way in the Organic Chemicals Division for more than a year. Believed to have been the first chemical company to initiate such a system, Cyanamid formerly used computer programs supplied by IBM. All chemical companies are invited to join in support of the project and to avail themselves of the opportunity to establish an SDI system within their respective industrial structures, CAS reports. Subscriber organiza tions would receive abstracts on tapes that are compatible with keyword pro files which they prepare based on their own scientific personnel. One of the more immediate benefits of the CAS-Cyanamid approach would be a lowering of the cost and enhancement of the quality of the abstracts. According to Philip K. Reily, di rector of marketing for CAS, "This joint endeavor with Cyanamid and other chemical companies is another experimental program which CAS is undertaking to benefit chemistry and chemical literature as a whole. Our five-year marketing plan calls for put ting Chemical Abstracts on magnetic tape by 1970, and this is certainly a step in that direction."

tions were on hand at the approach of the original April 1 deadline. The interest shown led trustees of the plan to extend the enrollment date for the benefit of members who de layed making application until sure that a plan was definitely in effect. Dr. B. R. Stanerson, Executive Sec retary, in a letter just mailed to mem bers, states that the plan represents a unique opportunity for ACS members to obtain coverage, regardless of phys ical condition, at a cost substantially below anything available individually. "For this reason," Dr. Stanerson said, "we are most anxious to be certain that the greatest number of members possible take advantage of the plan, and, to assist in accomplishing this, . . . the initial enrollment period will be extended to May 1, 1966." Although there is no medical exam ination, members are reminded that they must meet the "at work" condi tions. These require that the member perform all of the regular duties of his position during each regularly sched uled work day occurring during the four consecutive weeks immediately preceding the entry date. The application card and premium which members send to Connecticut General Life Insurance Co., Hartford, Conn. 06115, must be postmarked be fore May 1 to take advantage of the extension.
