Summary of studies by Dr. Theodor Bail tending to 

 show that viucor, saprolegnia, saccharomyces, and 

 «;«/?i5a are different forms ot the same fungus species, 

 and that insects may become infested with fungi if fed 

 with beer mash. Use proposed against injurious insects 

 generally. S. A. F. (4332)

 Experiments by Mr. J. H. Burns with yeast plant on 

 doryphora. Fifty treated beetles all died by the twelfth 

 day, while only three of the check lot of fiftv had died 

 in six weeks, and only twenty-five died during the 

 following winter and spring. Writer mentions also a 

 seemingly successful experiment on aphides. Sum- 

 marizes some recent European contributions to life 

 histories of etitomophthorae. Declares experimental 

 results independent of Bail's theory; and reports find- 

 ing fungus spores in sinus of wings of dead beetles 

 which had been sprinkled with yeast. Successful use 

 of yeast on aphides reported by letter from Germany.
