is now organizing in Paris in each arrondissement, 

 witti the idea of extending this movement to the 

 other towns of France. 8. That the Permanent 

 Committee of the Congress malte an official ap- 

 plication to the general management of the 

 Universal Exhibition of 1900 to bespeak its in- 

 terest in the work of prevention of tuberculosis 

 by studying, in conjunction with the Commit- 

 tee, the form in which instruction should be 

 given to visitors to the Exhibition as to the 

 means whereby tuberculosis is contracted and 

 can be avoided. 9. That periodical interna- 

 tional meetings be held for the study of tuber- 

 culosis, especially its prophylaxis. 10. That 

 governments should endeavor to devise means 

 of preventing or repressing the fraudulent use 

 of tuberculin for the purpose of concealing the 

 existence of tuberculosis in animals intended 

 for sale or exportation. The Congress, further, 

 considering that the constant increase of tuber- 

 culosis of bovine animals gravely threatens 

 public health and wealth, and that contagion is 

 the sole truly efficient cause of this increase, 

 affirms the urgent necessity of legislative meas- 

 ures enjoining (a) the separation of diseased 

 from healthy animals ; (b) the prohibition of the 

 sale of diseased animals for butcher's meat ; (c) 

 the supervision of cowhouses devoted to the 

 production of milk intended for public use as 

 food, and the immediate slaughter of every cow 

 affected with tuberculous mammitis ; (d) the 

 sterilization or at least the pasteurization of 

 milk intended for the production of butter and 

 cheese on a large scale ; (e) the generalization 

 of the service of inspection of butcher meat on 

 a plan more or less analogous to that which has 

 been in operation in Belgium for several years. 



GENERAL. 



Peofessor Koch is at present engaged in the 

 study of malaria in the hospitals of Milan, and 

 expects to make a special investigation of the 

 subject in Italy. 



A DINNER, at which Lord Lister will preside, 

 will be given to Professor Virchow on October 

 5th, on the occasion of his visit to London to 

 deliver the second Huxley lecture. 



The Americans in attendance at Cambridge 

 at the Congresses of Zoology and Physiology 

 were Professors Bowditch and Porter, of Har- 



vard ; Professors Osborn and Lee, of Columbia ; 

 Professors Marsh and Lusk, of Yale ; Professor 

 Mark, of Harvard ; Professor Baldwin, of 

 Princeton ; Professor Jastrow, of Wisconsin ; 

 Professor Lombard, of Michigan ; Professor 

 Watase, of Chicago ; Professor Atwater, of 

 Wesleyan, and Dr. Stiles, of the United States 

 Department of Agriculture. 



Professor William James, of Harvard 

 University, is at present giving lectures on the 

 Pacific Coast. These include an address before 

 the Philosophical Union of the University of 

 California, which, under the direction of Pro- 

 fessor Howison, is doing much for the advance- 

 ment of philosophy in America. 



Dr. Arnold Graf, the author of valuable 

 contributions to morphology, died in Boston on 

 September 3d, aged thirty years. A notice of 

 his scientific work will follow : 



Dr. John Hopkinson, the well-known Eng- 

 lish electrical engineer, was killed by an Alpine 

 accident, on about August 28th. The cable- 

 gram conveying this information states that his 

 son and two daughters were also killed, the 

 party having apparently fallen over a precipice 

 while ascending one of the high Alps without a 

 guide. Dr. Hopkinson, born in 1849, was a 

 graduate of London and Cambridge. He was 

 elected Fellow of the Royal Society in 1878 and 

 was elected President of the Institution of Elec- 

 trical Engineers in 1890 and again in 1895. He 

 hald contributed important scientific papers to 

 the Transactions of the Royal Society, but is best 

 known for his inventions in the application of 

 electricity. Dr. Hopkinson was intending to 

 visit America during the coming autumn. 



We regret also to record the following further 

 deaths among men of science abroad : Mr. J. 

 A. R. Newlands, who in 1887 was awarded the 

 Davy Medal of the Royal Society, in recogni- 

 tion of his discoveries regarding the periodic 

 relations between the atomic weights of the 

 elements ; M. J. M. Moniz, the naturalist, who 

 died at Madeira on July 11th, and M. Pomel, a 

 mining engineer, who made important contri- 

 butions to our knowledge of the Sahara. 



We were compelled to record some time 

 since the regretable fact that M. Grimaux, the 

 eminent French chemist, had been forced to
