“This volume is the outcome of five lectures on ‘ Regeneration and Experi- 
mental Embryology,” given in Columbia University, in January, 1900. The sub- 
jects dealt with in the lectures are here more fully treated and are supplemented 
by the discussion of a number of related topics. During the last few years the 
problems connected with the regeneration of organisms have interested a large 
number of biologists, and much new work has been done in this field, especially 
in connection with the regenerative phenomena of the egg and early embryo. 
The development of isolated cells or blastomeres has, for instance, aroused wide-+ 
spread interest. It has become clearer, as new discoveries have been made, that 
the latter phenomena are only special cases of the general phenomena of regen- 
eration in organisms, so that the results have been treated from this point of view 
in the present volume, which, however, has a wider bearing than simply as a 
treatment of the problems of regeneration.” — From the Author's Preface. 
“The presentation is thorough and comprehensive; besides original researches 
of the author, it involves a great deal of recapitulation and verification of experi- 
ments performed by others, with analyses and criticisms of the conclusions drawn 
from the phenomena or of theories advanced in explanation. Dr. Morgan is for- 
tunate in possessing experience, depth of insight, and a judicial habit of mind that 
give him special fitness for his task.” — The Nation. 
“Tt is rare indeed to find « book which contains so large an amount of re- 
search work and which is at the same time of such general interest and impor- 
tance. The book will undoubtedly take a prominent place among the standard 
biological works of the world.” — E. G. C. in Sctence.
