Abstract
PROF. OSCAR HERTWIG is well known as a pioneer in the researches on fertilisation. In 1875 he made the important discovery that the essential fact in the process lay in the fusion of a single male with a female cell, and he also saw and recognised the fusion of the nuclei. It was fitting that at the congress held at St. Louis last year he should choose this subject as the text of his lecture. The reprint forms a clear statement of the chief details of fertilisation, and also indicates some of the theoretical conclusions towards which modern cytology is tending. The sketch of the so-called “reduction divisions” is specially good, and the author shows how clear a light they throw on the modern experimental results obtained from the study of heredity. The lecture will be welcomed by all who are interested in these and kindred questions, and those who know Prof. Hert-wig's writings will not be surprised to find that if the treatment is of necessity brief, it is masterly of its kind.
