Excerpt from Synapta Vivipara: A Contribution to the Morphology of Echinoderms; A Dissertation

In February, 1896, through the kindness of Dr. W. K. Brooks, there were placed in my hands for study a number of specimens Of a small brown Synapta from Jamaica. In their body-cavities there were numerous young ones in all stages of development, so that an excellent Opportunity was Offered for working out the embryology. SO interesting did this prove that I gladly availed myself Of the privilege of spending the months of May, June, and July, 1896, at Port Henderson, Jamaica, in the marine biological labora tory of the Johns Hopkins University. For such a privilege I am under the greatest Obligations to the authorities Of that institution. During those months, I studied the segmentation of the egg and the early stages Of development from living material and Obtained an abundance of preserved material for further investigations. Since my return I have been engaged in a detailed study of the development and anatomy Of the animal under the direction of Dr. Brooks, and it gives me great pleasure to acknowledge the debt I am under to him for his suggestions and help.
