PREFACE
This volume is the outcome of a course of five lectures on “Regenerationand Experimental Embryology,” given in Columbia University in January,1900. The subjects dealt with in the lectures are here more fullytreated and are supplemented by the discussion of a number of relatedtopics. During the last few years the problems connected with theregeneration of organisms have interested a large number of biologists,and much new work has been done in this field; especially in connectionwith the regenerative phenomena of the egg and early embryo. Thedevelopment of isolated cells or blastomeres has, for instance, arousedwidespread interest. It has become clearer, as new discoveries have beenmade, that the latter phenomena are only special cases of the generalphenomena of regeneration in organisms, so that the results have beentreated from this point of view in th
