SOCIETIES AND ACADEMIES. 
Paris. 
Academy of Sciences, September 22.—Général Bassot 
in the chair.—A, Chauveau: Comparison of vigorous 
and feeble organisms from the point of view of their 
aptitude for receiving and cultivating virulent 
organisms. According to the views at present 
generally held, a strong, healthy man is less readily 
attacked: by tuberculosis or other contagious diseases 
than cases where the body has been weakened by 
alcoholism or other causes.. This view is strongly 
controverted by the author, who refers to the experi- 
mental infection in 1868 of sixty healthy animals by 
tubercle; not one escaped the infection. Additional 
experiments on the transmission of scab, to sheep are 
now given. Neither the healthy nor enfeebled sub- 
jects escaped.—T. Levi-Civita: “ Torricelli’s theorem

servations of the Metcalf comet 1913b, made at the 
observatory of Besancon with the bent equatorial. 
Data given for September 7 and 11. The comet was

Neujmin comet 1914c, made at the observatory of 
Besancon with the coudé equatorial. Data given for 
September to and 11. The comet was of the eleventh

plants. Réle of the root excretions in the absorption 
of iron from chalky soils. The presence of excess of 
chalk in the soil may produce chlorosis by rendering 
the iron insoluble. The addition of organic acids 
permitting the solution of small quantities of iron in 
presence of calcium carbonate removes the chlorosis 
at once.—Eugéne Pittard: The comparative analysis
