Sincere politicians would do well to have recourse to such recognized professional organizations or their spokesmen when it is felt that scientific advice has a role to play in the formulation of law or in molding social attitudes. UNIVERSITY OF ALABAMA-BIRMINGHAM CHAPTER, AMERICAN ASSOCIATION OF UNIVERSITY PROFESSORS Humanities Foundation In the discussions of the proposed National Humanities Foundation (31 July, p. 449) one important factor is left out by humanists and scientists alike. The present prosperity of science began during and after World War II when it was realized that scientific research had material value for the country. It could provide better national defense, better health, and better business and agriculture. I think the only reason that the American people and their elected representatives are willing to support science on such a magnificent scale is that they feel that science provides practical benefits for the country. It is realized that there is some basic research which does not provide direct practical benefits, but it is accepted anyway. Humanistic studies cannot provide anything as tangible as science can, and in the eyes of America's citizens they cannot ever be on a par. Of course, a large proportion of the basic research is not aimed at any practical aims and is comparable to linguistic, philosophical, and other humanistic studies. Support of such research is essentially support of higher education and general scholarly achievement. Perhaps instead of creating a foundation specifically for the advancement of humanistic studies, a National Research Foundation should be established to take over the support Office of the

Since that time there have been several significant additions to the OSHA standards, several deletions and an increasing involvement of the federal courts in the standard setting process. This paper reviews these changes with a particular emphasis on the areas of occupational health and industrial hygiene.

This work reviews the research which led to the determination of the particle sizes of respirable particulate and of the standard definitions of those sizes which were used to guide the development of size-specific air sampling instruments. The historical development of such instruments from the period before the First World War when samplers used the human lung as air-movers through the late 20th century which saw the introduction of real-time instruments which continuously measured full-shift airborne respirable dust concentrations in the breathing zones of workers. The dimensional definitions of respirable fibrous particulates such as asbestos are discussed as well as the instrumentation and measurement procedures. Proposals are made for personal dust measurements using the remote sensing of airborne dust concentrations coupled with wireless devices to locate workers within a dust cloud. Keywords: respirable dusts; particle size definitions; air sampling instruments; silica; asbestos; coal dust

Nor were the requirements embodied in the OSHA regulations created by government bureaucrats. The fact that certain materials used in industry cause illness among workers has been known for several hundred years. Methods of controlling occupational illness have been known for almost as long. The innovation of the Occupational Safety and Health Act is that all the known good practice procedures to maintain worker health have become government regulations which have the force of law. Any manufacturer who operates in the present and who expects to continue operating in the future should be aware of those regulations which pertain to his work, those regulations which are expected to appear in the near future and those procedures he is expected to follow even though they may not have been incorporated into specific regulations.

Bergmann (2) developed a new reagent, 2,4-dinitro-5fluoroaniline. This compound reacts with free amino groups in proteins, peptides, and amino acids to yield N-2,4-dinitro-5aminophenyl (DNAP) derivatives. These compounds are yellow like the corresponding DNP derivatives but their absorption maximum is at 410 my (2) compared with 350 rnp (3) for the DNP derivatives. Since this is further into the region of the spectrum visible to the human eye, the compounds are more readily seen (e.g., on chromatograms). Also, the derivatives contain free aromatic amino groups which can be diazotized and coupled with phenols, etc. to form azo dyes that absorb light strongly at 425 and 610 rnp (2) and are thus even more visible. This paper reports some work aimed at the exploitation of 2,4-dinitro-5-fluoroaniline as a reagent for the determination of N-terminal groups in proteins and peptides on an ultramicro scale.

Cell wall mucopeptide of Bacillus anthracis, strain VIB-I89 was prepared from cells grown in the presence and absence of penicillin. Both types contain an unusual inner membrane. 2. These were analysed for reducing sugars, amino sugars and amino acids. Both types contained glutamic acid, alanine and diaminopimelic acid as the principle amino acids in the mole ratios of I : 1.5 : I. 3. Penicillin did not change the relative amounts of the different cell wall constituents but it did reduce the weight of all constituents per unit weight of mucopeptide.
