xvi, Crawfordsville, Ind., Oct. 16, 1891, p. 297. 
Notes that this species, previously supposed to be confined to Quercus agrifolia , has been 
found by S. M. Tracy ou various species of oak in Mississippi and by Atkinson in Alabama.

Calls attention to paper by Smorawski in which it is stated that mycelium of the potato- 
rot fungus produced conidia and also ocigonia-like bodies, regarded by him as antlieridia. 
The reviewer does not consider that Smorawski’s idea is fully proven by his investigations.

Gives details of experiments with peas, tomatoes, and wheat planted in soils containing 2 
and 5 per cent of copper sulphate, mentioning the differences in germination, foliage, period 
of maturity, number and weight of seed, root system, etc. The results point to the fact that 
the presence of copper in the soil in large quantities is injurious to plant growth. (J. F. J.)

A continuation of an article published in some previous numbers on the subject, detailing 
what has been found out concerning wheat rust, discussing the wheat, soil, rust, and 
weather; also detailing the results of an examination of rust-resisting varieties of wheat 
in the structure of the cuticle, the tensile strength of the leaves, and the presence of stomata. 
Appendices contain measurements of the thickness of wheat leaves, width of the same, the 
tensile strength, and notes on the number of stomata observed. (J. F. J.)

A popular description of the good results arising from the presence of bacteria, especially 
as related to farming industries. Points out the agency of the organisms in the production 
of butter, cheese, beer, vinegar, etc. (J. F. J.)

After stating that certain species of fungi have a world wide distribution, the author 
says that other species occur only in countries far apart. As an example of this he points 
out that many of the species of fungi characteristic of Ceylon occur also in Australia. A 
number of species are cited, these being mostly large forms, such as Polyporei, Agaricini, 
etc. (M. B. W.)

Several experiments are described to show the possibility of infesting larvae of the May 
beetle with Botrytis. The fungus was taken from pure cultures upon potato and from dead 
larvae which had been killed by the fungus. The result shows that infection can take place 
from living larvae, but the spreading of the infection, especially in the field experiments, 
was less than stated by French authors. Many larvae were observed to be able to resist 
the infection for the three months during which the experiments were made. (T. H.)

One specimen came from an inch and a quarter below the surface. Where a second forced 
its way up the fragment of cement displaced by it was found a foot away. (J. F. J.)
