A study of the metabiotic action of ultraviolet rays. — Modification and 

 heredity of characters in the anthrax bacillus, Mmk. V. IIenui (Compt. Rend. 

 Acad. Sci. [Paris], 159 (1914), No. 4, pp. 340-^43, pi. i).— The author has fol- 

 lowed up the work previously reported (E. S. R., 31, p. 379) with a further 

 study of the anthrax bacillus as affected in its morphological and biochemical 

 characters by culture under the influence of ultraviolet rays. 



The characteristic arrangement of the bacilli in filaments was strongly modi- 

 fietl when gi-own in an alkaline or saccharin medium. The form and size of 

 the rods were also changed. Other charactei-s showing considerable alteration 

 were responsiveness to the Gram stain, production of pigments, and formation 

 of amylolytic and proteolytic ferments. The persistency of the characters so 

 acquired was noteworthy; changes tending toward the normal form were in- 

 duced in one strain by passage through the guinea pig. 



Beport of the departmental committee appointed by the Board of Agri- 

 culture and Fisheries to inquire into foot-and-mouth disease, S. Stockm.\n, 

 J. McFadyean, aud A. E. 'Mf.tt am (Rpt. Dcpt. Com. Bd. Agr. and Fisheries 

 [Gt. Brit.], Foot-and-Mouth Disease, 1914, PP- 32, figs. 6; ahs. in Jersey Bui. 

 and Dairy World, 34 (1915), No. 1, p. 11). — This is a report of a departmental 

 conmflttee appointed by the Board in June, 1912, to make an investigation of 

 the characteristics of foot-and-mouth disease and the manner in which it is con- 

 tracted and spread. 



The investigation was carried out in India. The total number of animals 

 employed in the experiments was 228, including 165 cattle. 23 buffaloes, sheeji. 

 11 goats, and 20 pigs. Infection was attempted by contact, intravenous inocula- 

 tion, scarification, subcutaneous inoculation, and feeding. 



In 49 experiments embracing 147 animals the results were entirely negative. 

 In the remaining 18 experiments with 81 auimals of which 37 became infected 

 the results were as follows: Intravenous inoculation infected 12 cattle and 

 3 buffaloes, and failed to infect 10 cattle and 1 buffalo; inoculation by scarifica- 

 tion infected 8 cattle and 1 pig (2 doubtful), and failed to infect 4 cattle and 

 1 bufl'alo; subcutaneous inoculation infected 1 pig and failed to infect another; 

 and contact with diseased animals led to the infection of G cattle and 1 buffalo, 

 and failed to infect 12 cattle, 3 sheep, and 5 goats. 



In the great majority of cases the period of incubation after intravenous in- 

 oculation was two days, but in one animal the first lesions developed on the 

 tenth day after inoculation. In cases of infection produced by scarification the 

 period of incubation varied from two to eight days and after contact from three 

 to 13 days. 



In 25 cases the period within which ulcers developed in the mouth did not 

 exceed 24 hours, but in 12 new cases fresh vesicles appeared ou two or more 

 successive days. It was found that in the morning ulcers might be present in 

 the mouth of an animal which on the previous evening showed no abnormality 

 of the mucous membrane.
