    the distension produced during early development at least in the rapid production of thin-walled, nucleated cells. Possibly both may be right. It seems highly probable that, in the smaller cysts, large cells with fluid contents constitute the first stage of the disease, and, later, these cells form themselves into spaces traversed by trabeculse of connective tissue, and containing the fluid. This is identical with the process by which the gelatin of Wharton is produced in the cord. The exuded fluid in both cases has all the chemical reactions of mucine. It is bv no means uncommon to find in the extremity of a com- paratively healthy villus one or more large transparent hyaline cells. These represent the beginnings of the cystic change, or the first transformation from the more uniform cell-structures which compose the parenchyma in a normal state. Ercolani* (who wrote in 1876) differs in toto from Virchow and other authors in his view of the pro- duction of cystic chorion, and, disbelieving in its myxomatous origin, he regards Virchow's appellation for it as misleading. He, like Virchow and Eobin, describes a villus as composed of two parts : one internal or parenchymatous (tissue chorial of Robin, mucous tissue of Virchow) which is in direct com- munication, and in fact continuous, with the chorion. Besides, this is an external portion, which constitute^ an outer envelope or casing to the villus (the exo- chorion of Robin). Before the villus penetrates the decidua, this outer envelope is constituted of an epithelium which belongs to the foetal structures, but directly the villus is embedded in the decidua to * Loc. cit.
