 taceae ma\- rexeai, when (he authors have completed the four, 

 volumes which will comprise the work, some further data on 

 these problems of distribution. Not the least valuable feature 

 of the book is the basis it will furnish for such studies, and in the 

 final volume it is to be hoped the authors will include such data. 



Something has recently been issued or spoken about coopera- 

 tion in science. This attack upon the problems of the Cac- 

 taceae, largely engineered by Messrs. Britton and MacDougal, 

 has secured the cooperation of the Carnegie Institution, New 

 York Botanical Garden, U. S. National Museum, U. S. De- 

 partment of Agriculture, and the Gray Herbarium. Add to this 

 hosts of individuals who have contributed notes or specimens 

 and it is little wonder that, under the guidance of the authors, 

 the book should have grown into incomparably the best one on 

 its subject that has yet appeared.
