A 54-year-old Jamaican employed as a grinding machine operator developed pulmonary anthrax and died within two days. In the eight days before his illness he had been grinding sterilized bone charcoal delivered in second-hand sacks, some of which had been used to import the raw bone before its sterilization. Bacillus anthracis was isolated from four out of six sacks examined and is considered to have been the source of the infection.

Studies on Fertility, edited by R. H. Harrison, is a collection of selected papers read to the Society for the Study of Fertility in 1954, augmented by "papers of high standing" which had not been read. This volume replaces the Proceedings of the Society, which had increased in size so rapidly as to become unwieldy. The papers in this present volume do not cover the whole field of fertility, but represent up-to-date opinion-on such subjects as the " mechanotherapy of impotence" (i.e., splinting the penis), the management of pregnancy in previously infertile women, gynaecological coelioscopy, enzyme inhibitors in contraception, the aetiology of male subkertility, and testicular biopsy. studies on Fertility, which costs £1 ls., is published by Blackweltl Scientific Publications, 24-5, Broad Street, Oxford.

Previous authors (Pugh and Gaze, 1966;Wagstaff et al, 1969) have reported favourably on the use of the Technicon AutoAnalyzer for automation of the CWR and RPCFT, but one of the main problems seemed to be the continuous flow system's limited rate of testing. If all specimens were tested against cardiolipin and Reiter antigens separately, and all those giving positive or doubtful results were retested against complement alone, it would be difficult to test more than 150 samples each day as allowance must be made for the time required to prepare the machine for use, to wash it through after testing is finished, and to transcribe the results. This would not be considered a significant improvement on the manual test. It is, of course, possible to
