CURRENT: LITERATURE. 
Minor Notices. 
THE SECOND VOLUME' of biological lectures deliveréd at the marine ’ 
biological laboratory of Woods Holl has récently appeared, the first 
volume having appeared in 1890. Ten lectures are included, all given 
by investigators upon subjects connected with their own work, and all 
présenting current problems. It would be impossible to review a work 
made up of so many important and independent ‘parts, and where ' 
each part is the compact presentation of a large subject. It is suffi- 
clent to indicate such titles as are of botanical or general biological 
interest, and to’ state that ‘this ‘collection’ of lectures is one that every: 
student of biology'should réad. The botanical and ‘biological titles 
are: The mosaic theory of development, E. B. Wilson; The fertiliza- 
fon of the ovum, E. G. Conklin; On some facts and principles of 
physiological ‘morphology, J. Loeb; Dynamics: in’ evolution, J. A: 
det; On thé nature ‘of ‘cell organization, S. Watasé; The inade- 
quacy of the cell-theory of development, C. O. Whitman; The influence* 
of external conditions on plant life, W. P. Wilson; Irrito-contractility’ 
implants, J. M. Macfarlane:
