To quickly assess the difficulty of the text, read a short excerpt:
None of them survived. There were collected at the same time, October 2, and at the same place, fifty other beetles, which were kept in the same room. Of these, which were not sprinkled, to Nov. 14th only three had died, and March ist twenty-five lived still brightly. The experiment is so far a decided success, as it has proved that insects are killed by the application of yeast I may add that an experiment made a few weeks ago in a green-house seems to be suc- cessful in killing Aphides. Dr. M...etschnikoflf has published a pamphlet, Odessa, 1879, and a record of it, Zool. Anzuger, 1880, Feb., concerning his experiments in destroying obnoxious insects (Anisoplia and Cleonus) by the application of fungus. The difficulty of raising the fungus chosen by him (Isaria vixescens) in sufficiently large quantities he hopes to overcome by raising the Isaria in beer-mash. Mr. A. Giard, Lille, France (Bull. So. de Department de Nord., sec. 2, An. 2, No. 11), has pubhshed a paper containing very interesting facts regarding insect epizootics.
