520 |a"In 1880 W. K. Brooks published a paper on the development of the American oyster. He did not have time or opportunity to go into the matter very deeply, but on the strength of such evidence as he could collect he gave it as his opinion that the sexes were quite distinct and that no change of sex took place during the life time of the oyster. This opinion has never been seriously contradicted and is still quoted but recently it has been suggested that some change does take place. The writer has been endeavouring to prove the truth of this assertion"--Page [1].
