cing thereby fatal animal tuberculosis. He 

 also says he has rendered cattle immune 

 against tuberculosis by vaccinating them 

 when they are young. 



At the annual meeting of the California 

 State Medical Society, held April 15-lY, the 

 following resolution was adopted: "Whereas, 

 the Mayor of the city of San Francisco has 

 seen fit to remove the so-called old Board of 

 Health; and whereas, the chief executive 

 of the city has stated that he has determined, 

 after a prolonged personal investigation, that 

 bubonic plague has never existed in San 

 Francisco; and whereas, the position is abso- 

 lutely unsupported by any competent, unpre- 

 judiced physician who has made personal ex- 

 amination of suspects or alleged cases of 

 plague before or after death, or who has exam- 

 ined the bacteriological evidence presented, 

 and is further in direct conflict with the find- 

 ings of the Federal • Government experts and 

 Special Commission; therefore be it Resolved, 

 That the Medical Society of the State of Cali- 

 fornia emphatically condemns this action on 

 the part of the Mayor of San Francisco, and at 

 the same time endorses the position always 

 maintained by the old Board of Health in its 

 sanitary defence of the people of the city of 

 San Francisco and of the country at large. 



We have been requested to print the follow- 

 ing note : 



Between September 21 and September 28, 1902, 

 the AssociatioiL of Natural Phylosophers and 

 Physicians will hold its 74th Annual Congress at 

 Carlsbad, the Austrian Spa. As on former occa- 

 sions the rule that lectures and debates may be 

 carried on in any language of the world, will be 

 adhered to, and to English, American, French, 

 Spanish, etc. Natural Phylosophers and Physi- 

 cians the same privileges will be again accorded 

 as the ordinary members of the association are in 

 the habit of enjoying.- It is estimated that be- 

 tween 6,000 and 8,000 representatives of Natural 

 Phylosophy and Physicians will gather on that 

 occasion at Carlsbad, and great preparations are 

 made now already, at Carlsbad, to receive the 

 members and friends of this famous association. 

 Nearly all the principal professors of the Berlin, 

 Vienna, Prague and most of the other Continental 

 universities and high colleges will again be pres- 

 ent, and 28 different branches of modern and 

 ancient sciences will form the programme for the 



lectures and debates. As several hundred inhabit- 

 ants of Carlsbad understand and speak English, 

 the place being annually frequented by a few 

 thousand bathers and tourists from England and 

 America, the facilities, comfort and convenience 

 available for English and American Natural 

 Phylosophers and Physicians, at this year's con- 

 gress, will be by far greater than on any former 

 occasion, but those intending visitors of the coi- 

 gress who wish to hold lectures should give notice 

 of this intention at an early date, as the number 

 of lecturers will be very large. We are requested 

 by the secretary of the association to inform our 

 readers that this Association of Natural Phylos- 

 ophers and Physicians pursues solely and ex- 

 clusively the object of promoting and developing 

 all branches of science, and that any other object 

 of whatever kind it may be, is strictly excluded. 

 At the small exhibition of scientific objects which 

 will be held in connection with the Congress, no 

 charge will be made to exhibitors for the space 

 required, nor mil any entrance fee be asked from 

 visitors. Enquiries or letters should be addressed 

 to ' Tlie 74th Congress of Natural Phylosophers 

 at Carlsbad.' No stamp for reply need be enclosed. 



We learn from the London Times that Major 

 Ronald Eoss has submitted to Sir Alfred L. 

 Jones, chairman of the Liverpool School of 

 Tropical Medicine, a report on the anti- 

 malaria work accomplished on behalf of the 

 school in Freetown by Dr. Logan Taylor since 

 his arrival last July. Employing about seventy 

 men. Dr. Taylor has drained nearly the whole 

 of the most pestilential parts of the town. The 

 areas which have been dealt with were formerly 

 full of hollows, pits and ill-made drains, 

 which in the rainy season contained pools of 

 stagnant water, breeding swarms of malaria- 

 bearing mosquitoes. In addition to the work 

 of drainage Dr. Taylor has employed a gang 

 of men to collect old tins, bottles and other 

 rubbish from the houses, and 2,257 cart-loads 

 of such refuse have been removed and 16,295 

 houses have been visited. The effect of these 

 measures has been a demonstration of the pos- 

 sibility of getting rid of mosquitoes in Free- 

 town, and therefore, probably, in any town. 

 The moral which Major Eoss draws from the 

 results of the work done is that in order to 

 make the principal West African stations 

 healthy they must be rendered scrupulously 

 dry and clean. Nothing else will remove the
