1. A quantitative comparison has been made of the observed mortalities from respiratory tuberculosis with those expected from a simple scheme of generation mortality.

2. This scheme gives a good account of the observed rates until about 1930, but is unsatisfactory thereafter.

3. It is concluded that these discrepancies cannot be due to chance, and that the generation effect has become obscured by other factors.

4. In particular the shift of maximum mortality into later life is not directly explained by the hypothesis, nor is such a shift a necessary consequence of the generation hypothesis of mortality.

I am greatly indebted to Dr J. C. McDonald for advice and constructive criticism during the writing of this paper; my thanks are also due to Dr G. S. Wilson for his comments.
