The influence of heredity upon tuberculosis, A. Latham {Lancet [London], 

 JfiOS, II, Xo. 21, pp. I'>l2-I.jl 'i). — Some of the conclusions di'awn by the author 

 following a general survey of the subject are as follows: "The hereditary 

 transmission of the germ is so infrequent that it is a negligible factor. 



"The incidence of tuberculosis depends in the main on two factors — (a) 

 exposure to infection, which in turn is governed by the dose received and the 

 virulence of the particular strain of bacillus; and (b) tlie undermining of the 

 resistance of the individual l)y insanitary conditions and by disease. . . . 



" There is some evidence to suggest that the diminishing incidence and mor- 

 talty of the disease may be in part due to a partial immunity inherited in the 

 course of generations from tuberculous ancestors in whom the disease has been 

 cured. 



" The theory that there is an inherited predisposition to tuberculosis is based 

 on insutficient evidence."

 International Congress on Tuberculosis, held at Washington, in which a detailed 

 account is given of the use of tuberculin. Attention is called to the imitortauce
