Scharff describes a series of researches which were carried out while acting as assistant to Professor [William Carmichael] McIntosh, at the St Andrews Marine Laboratory [Fife, Scotland; later replaced by Gatty Marine Laboratory]. The chief material consists of the intra-ovarian ovum of the gurnard (Trigla gurnardus), though several other marine forms are examined. The paper is divided into five sections: 'The nucleus and its changes in the smaller ova'; 'The larger ova and the formation of the yolk spherules'; 'The egg membranes'; 'The follicular layer'; and 'Development'.

Annotations in pencil and ink throughout.
