ural processes prevalent about us. The plants, though injured in 
their growth and their consequent powers of absorption, by the 
quite acid solutions used, showed as high and higher percentages 
of mineral matter in the ash as did the water-fed plants which were 
unimpeded in their nutritive processes by an injurious treatment. 
Experiments may now be undertaken upon phosphatic (insoluble 
phosphate) soils with the same means.—Z. P. Gratacap, New

BoranicaL News,—Papers on the following subjects occur in

is devoted wholly to a description of the North American species 
of Gloeosporium, forty-seven in all. In Grevillia, M. C. Cooke 
describes a large number of new British Fungi; and Cooke and 
Plowright describe twenty California Fungi, including one inter- 
esting rust, Uromyces puncto-striatum, on twigs of Rhus. e
