The Radiocarbon Dating Laboratory of the University of Texas was reorganized in late 1962. The dates reported in this list were obtained from February to November, 1963. The laboratory uses liquid scintillation counting with benzene solutions (Tamers, Stipp, and Collier, 1961; Noakeset al., 1963). The chemical synthesis has been modified and improved in several ways in order to permit one worker to produce a sample per day.

This lecture is a report of progress in work that began at Shell Research Ltd’s Milstead Laboratory and has continued at the University of Sussex. I had spent some ten years studying the substrate sterochemistry of enzymes. No one who has done this could fail to be impressed by the stereochemical precision with which enzymes handle their substrates, even when the nature of the product does not exact a stereospecific treatment. It is hard to resist the conclusion that this specificity is an integral and not an incidental feature of the enormous efficiency of enzymes as catalysts. Naturally, like everyone who has worked with enzymes, I form hypotheses about this or that enzymic catalysis; some of these ideas have been testable by stereochemical methods or by various types of isotopic labelling. Further progress can be, and is being, made by the intensive study of particular enzymes, but to someone like myself who is interested in chemical reactions and chemical synthesis it was more attractive to attempt, on the basis of knowledge and conjecture about the nature of enzymic catalysis, to devise synthetic catalysts having the properties of stereospecificity, positional specificity and high efficiency. Without at present presuming to excel or even equal catalytic powers that are thought to have evolved by trial and error over thousands of millions of years, one can, by making the assumption that catalytic activity of this type is not uniquely a property of proteins, substitute the resources of organic chemistry as a whole for the rigours of polypeptide synthesis.

The fifty-second meeting of the Modern Language Associationof America was held, on the invitation of the University of Cincinnati, at Cincinnati, Ohio, Monday, Tuesday, and Wednesday, December 30 and 31, 1935, and January 1, 1936. The Association headquarters were in the Netherland Plaza Hotel, where all meetings were held except those of Tuesday morning and afternoon. These took place at the University of Cincinnati. Registration cards at headquarters were signed by about 900, though a considerably larger number of members were in attendance. The Local Committee estimated the attendance at not less than 1400. This Committee consisted of Professor Frank W. Chandler, Chairman; Professor Edwin H. Zeydel; Professor Phillip Ogden; Mr. John J. Rowe (for the Directors); and Mr. Joseph S. Graydon (for the Alumni).

Nowadays more and more of the reductions of astronomical data are made with electronic computers. As we in Uppsala have an IBM 1620 at the University, we have taken it to our help with reductions of spectrophotometric data. Here I will briefly explain how we use it now and how we want to use it in the near future.
