The author carried out the Pirquet test with old tuberculin prepared at the Bacteriological Institute of Chile among various groups of the population of Santiago with the following results: (1) Fourth year medical students a~ed 20 to 1:l5 years. Of fi6, 46 (82'14 per cent.) were positive and 10 were negative. (2) IIospitnl nurses. Of 20, 15 (75 per cent.) were positive. and 5 (25 per cent.) were negativp.. (3) Conscripts. Of 97, 51 WH7 per cent.) were positive and 46 (47'43 per cent.) were negative. (4) Of 96 inhabitants of rural areas 29 (~0'20 per cent.) were positive and (\7 (69'80 per cent.) were negative. Without drawing any conclusions while his work is still in progress, the writer maintains that the
517
population of Chile has a low index of tuberculinisation, especially in the country districts, and suggests that the gravity of certain forms of tuberculosis may be due to this cause.

The author carried out the cutireaction on 3,186 persons in Rio de Janeiro, of whom 736 were infants, 1,288 young children, 664 school children, and 498 adolescents. Indication of tuberculous infection as shown by n positive reaction was as follows: 3'5 per cent. in infants, 22'2 per cilllt. in young children, 60'5 per cent. in scbool children, and 79'7 per cent. in adolescents.
OBITUARY NOTICES. ANTON GHON. April 23, 1936. THE name of Anton Ghon has become a household word in tbe study of tuberculosis.' He was born on .Tanuary I, 1866, in the little town of Villrtch and came of Slovak ancestry, though for several generations the family had been naturalised Germans. lie was educated in Villach and later iu Graz, qualifying as a doctor in 1890. He first worked under Neusser in his Dermatological Clinic, and later for a few months he engaged in general practice in Vie una, but this kind of work did not attract him, aud in 1894 he became assistant in the Institute of Pathological Anatomy in Vienna, receiving in 1902 the title of Professor. In 1910 he succeeded Rudolf Kretz in the Chair of Pathological Anatomy in the University iu Prague, a post which he held until shortly before his death. . Ghon's scientific bent was directed from the beginn'ing towards the study of infectious diseases, largely through his teacher Weichselbaum, whose colleague and right hand he became,
collaborating with him in his classical work on the meningococcus. His otheL' studies included work on bubonic plague, tbe gonococcus, the influenza bacillus, and anaerobic bacteria, and during the Great War, in wbich he worked partly in Dalmatia and partly at the Italian front, he made important contribntions to the study of dysentery, typhus and malaria. All this work, however, was eclipsed by his researches on the subject of tuberculosis. In 1912 he published his celebrated monograph on the Primary Focus in Pulmonary Tuberculosis in Children. In amplifying the older studies of Parrot and Kiiss, Ghon, through his careful work, definitely established the facts that this was the usual type of childhood tuberculosis, that in more thall 95 per cent. of the cases the primary focus was in the lung, and that its origin could only be aerogenous. From this time Ghon tirelessly carried on his work on tuberculosis, publishing alone and with various colleagues a large number of studies 011 the primary complex and on the mode of spread of tuberculosis in infants and children.
