SUMMARY. (1) The evidence relating to the effect of polygyny on the sex‐ratio in man is conflicting, but the result, if any, appears to be a rise in the proportion of males. (2) In horses Düsing has shown that the proportion of males rises with increased stud work. (3) The experimental work on mice described in this paper shows that in this mammal a rise in the pescentage of males follows polygynous mating, and therefore supports Düsing's results.
