'ya:\y gains from other countries. Last year almost 2,000 donors from Die Commonnealth alor.o applied to enter Britain. In I Odd, tiio most recent year for which figures arc available, there were 0,000 doctors working in National Health hospitals who had been bom now rani, abroad--about 00 per cent of the total. Of general practitioners 2,000, or 12 per cent of tho total, were born abroad. If every doctor were to practiso in the i\ of wr-- country of his birth, Britain would not be tho gainer. But this is not to decry any efforts that tho ministry may now make to cncourago tho return of expatriates, and to allay the discontent of those who would follow will them. VOiul : its to "I t'O 'it.ain nedi- cters been ituir* More on Asbestosis That there are risks associated with asbestos is not now disputed. A review of the problem as it occurs in Britain has just been published as a memorandum by the Advisory Panel on Problems Arising from the Use of Asbestos (H.MSO, S.s. 0d.). The advisory panel, set up in 10C3 by HM Factory Inspectorate, is respon sible for considering the use of asbestos in relation to the health of those directly or indirectly exposed to .(i asbestos in their occupations. Over tho whole country had tho panel estimates that about 20,000 persons ore :i for exposed to asbestos in tho use or handling of the fibres. loing Tho figure is probably higher than this; people can . the easily bo put at risk by working near to where asbestos r:;Uc is handled. The present Asbestos Industry Regulations, k>o;'.s # 1931, arc applied to some 300 registered factories, but 'Got* tho report says that there arc many other factories -y of which use asbcsto3 products and which do not como i.UU within the regulations. Tiia Ministry of Labour is at ;a\y present drawing up new regulations to cover a wider a ad range of factories. .tj vO It was in the 1920s that it was first clearly recognized . the that asbestosis, a fibrotio condition of the lungs, is emic caused by occupational exposure to asbestos. Within .:e!v a tew years it was suggested that the disease might be complicated by the development of Carcinoma of the c:a, t lung, but an association was not generally accepted titc until the 1950s. Pveccntly, thcro has been concern over i an the occurrence of mesotiielial tumours of tho pleura ' v:t! or peritoneum which appear to bo causally related to C ib asbestos exposure in many eases. Since 1006 meso Vcta thelioma has been a scheduled industrial disease. d to The advisory panel concludes that there is an :urh increasing incidence of asbestosis in the country: The Inert likely explanation for this inrrensri in llm ov.i greater ure of'asne-.n-.-i and lhe greater numbers of people employed in tho industry over the past 20 years. But the panel says that "there is no evidence that the overall attack rate has decreased in tin indus- fh-d try over this period, although it has in some textile mills in which the dust conditions have beon greatly ' ` ! j | ^ , UCC 02f)773 NATUHE. VOL. 217. JANUARY 13. 1903 improved". It appear* that if (lie n gnlal ions are i.v.rc widely and more stringently applied than at ore.s< flip number of eases should inevitably fall. Tho panel indicates that crocidolite. has a special significance in relation to mcvjthc.'ia! tumours. recommends that other types_nf fibre sbo; stltutcd foFTroetdolitc wherever possible, and, wl, , this ia impoiQs.ssibihllec, special precautions should he x:.\: v j ' to reduce th' e risks of inha~ling the inatr-riaC Ti. J parrel admits that at tho moment the level of expos:..-.'" below which the risk may be negligible is not known. The quantity of crocidolite (blue asbestos) import"; into the country is much less than the other varieties of asbestos, anrl it has remained at about 7///t tor.per year for the last few ycar3. But time mav -i.n v that other fibres are also implicated in the development of mosothclial tumours. Finally, the report suggests that aerioti .should be taken to control t he discharge of dust-laden air from asbestos factories and the dispersal of dust from v. a-> dumps. It emphasizes, however, that the problem of mesothelioma in association with asbestos exposure should bo kept in a proper perspective. Even thomd tho incidence is increasing, the total number of ca.-.ei of mesothelioma in Britain over several years is vcr. small when compared with the annual total of death? lrom cancers of tho trachea, bronchus and iumr. c/6Ae.e rrz'j r" Recording Weather Ak outomatic weather recording station which car. oporato unmanned for nf least three months has be.-p. produced by the Plessey Company Ltd. Tip's station, which can make and record moro than 82,590 measure ments in a three month period, is available from the Marino Systems Division of the Plesscy Electronics Group at Ilford. The value of automatic weather Btations was recognized by a recent report from the World Meteorological Organization (Xnhtrt, 215, 1324: 1967). They are important because modern, dc-ve'.op- menta in weather forecasting require information a hour climate from all over the world--sometimes from un inhabited areas--and it H becoming increasingly hard to persuade amateur meteorologists to provide accurate data day by day. Professionals cost money, and so there should be a real market for autemat:. stations which can do the job reliably for long periods without attention. The PJc6sey station 13 virtually self-contained and can monitor parameters such os rainfall, humidity, wind speed and direction, air, soil and water temper., turca, barometric pressure, pH, solar radiation nr.d water level and flow. The basic design was evolved In co-operation with the British Water Resources Board, tho Meteorological Office and the National Physical Laboratory. By adding various instruments to ti e basic design, it has been possible to produce a famdy of stations including hydrometeorological. climato logical, water level, water quality and riveraina rair.fr.'.l stations, jvu-ii can he arranged f"r ic'eMi.iir n; .
