RECENT LITERATURE. 
A New Eprrion oF Sacus’ Borany.' It is now more than 
seven years since the English-speaking and reading botanists were — 
laid under great obligations to Macmillan & Co., for bringing out — 
the translation of the third edition of Sachs’ Lehrbuch, made by — 
Bennett and Dyer. During this period it is safe to say that no | 
single book on morphological and physiological botany has been — 
more studied and consulted by advanced students, and it is 
not too much to affirm that few books have ever exerted a more — 
beneficial effect upon a science, than it has in England and Amer- 
ica. We have now a new English edition of this important work, © 
based upon the fourth German edition of the Lehrbuch, but with — 
many additions, corrections and modifications by Dr. Vines, who, — 
for some years has been well known as a careful student and in- 
vestigator. re 
It would be impossible within the limits of an ordinary review 
to notice the peculiarities of the new edition, containing as it does — 
over one hundred pages more matter than the old one. New para-

occur here and there in the body of the book, and especially in 
the appendix. We note with pleasure the remark [Appendix, p- 
955], that as the nuclei of the coalescing myxoamcebe remain 
distinct, “the plasmodium can no longer be regarded as the 
equivalent of a zygospore, and the position of the Myxomycetes 
among the Zygomycetes is untenable.” This relegates the Myxo- 
mycetes to the Protophytes, where they were first placed by 
Fischer, and subsequently by us in our “ Botany.’?
