ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 391 



Some Aspects of the Mycorhiza Problem.* — B. C. Gruenberg gives 

 an historical sketch of our knowledge of mycorhiza and of the literature 

 published on the subject. He discusses some of the problems connected 

 with the fungus : its importance to the symbiotic plants, its special func- 

 tion in regard to such plants as Goralhrhiza, Orchids, etc. He suggests 

 the practical bearing of these problems on transplanting of trees, reforest- 

 ation, tuberisation, nitrification of the soil, etc.
