The amino acid sequence of the cytochrome c' from Alcaligenes sp. N.C.I.B. 11015 (Iwasaki's ;Pseudomonas denitrificans') has been determined. This organism is the only non-photosynthetic bacterium in which the protein has been found. The protein consists of a single polypeptide chain of 127 residues, with a single haem covalently attached to two cysteines. Unlike normal cytochromes c, the haem attachment site is very close to the C-terminus. The amino acid sequence around the haem attachment site is very similar to that of Chromatium vinosum D cytochrome c'. Detailed evidence for the amino acid sequence of the protein has been deposited as Supplementary Publication SUP 50022 at the British Library (Lending Division), (formerly the National Lending Library for Science and Technology), Boston Spa, Yorks. LS23 7BQ, U.K., from whom copies may be obtained on the terms given in Biochem. J. (1973) 131, 5.

It has been documented that hospitals with records retention programs have 55 percent less records, spend less time on record maintenance and retrieval of records and can find records on demand when requested. This all adds up to savings in time and space and improved quality in an age when these commodities are precious resources. No other industry that I can think of has as its mainstay the need for good quality records as hospitals do. Don't pass up this opportunity to manage your records as carefully as you have been managing your other resources: money, manpower and materiel.
The design of laboratory archives depends to a large extent on frequency and type of access required. This article reports a study in which all requests for laboratory archival data were tabulated carefully. Such requests are infrequent and usually involve specific test results. An inexpensive, efficient, and convenient method of storing such data is described, employing a laboratory computer and magnetic tape-to-microfiche software. The efficiency of this system permits indefinite storage which may be desirable in view of the medico-legal climate.
The development and early activities of the Milton Helpern Library of Legal Medicine is narrated by Dr. Milton Helpern. The offshoots of the Library are discussed, including the International Microform Journal of Legal Medicine, which was the first journal of its type in medicine. This has been continued after the death of Dr. Helpern by the new editor, Dr. William G. Eckert of Wichita, Kansas, and the Director of the Milton Helpern International Center of Forensic Sciences at Wichita State University. Its new name is the International Microform Journal of Legal Medicine and Forensic Sciences.

The present study was undertaken to examine experimentally and clinically whether a 100-mm roll-film digitizer and image processing device could preserve or increase the diagnostic accuracy of 100-mm roll films used in the mass screening of patients for lung cancer and provide picture archives of high enough image quality to replace the original films. The quality of the processed digitized CRT image was found to be only slightly less than that of the original films. There was only a slight decrease in diagnostic accuracy, and the system was judged to be potentially useful as a miniature picture archiving and reference system.
