ABSTRACT
Having just received Mr. Duerden’s new and valuable work on ‘The Coral Siderastrea Radians audits Post-larval Development,’ 1 I wish to draw attention to one or two of the points in which his work covers the same field of investigation as my work on ‘Madreporarian Types of Corals,’2 published in 1896. My work in no sense professed to be a study of the histology of Madreporarian corals ; it explicitly dealt with the coral skeleton, and it set forth, for the first time, the exquisitely fine lamellar structure of the skeletal parts. My microscopic observations of skeletal structures have been verified by many students since the work appeared, but zoologists generally have regarded my view that the crystalline deposit took origin within organic tissue as quite wrong. Mr. Duerden, who approaches this subject from the histological standpoint, arrives at results which, in this very important feature, corroborate my view.
