How to Grow Some Common Moulds 



Report of Address by Mr. Tabor, B.Sc, Royal College of 

 Science : 



The study of moulds is possible even in schools where no micros- 

 scope is available, and by such study certain facts of elementary 

 physiology can be taught, e. g., the advantages of different kinds of 

 food material, the effect of temperature, light, moisture, etc. 



For the minute study of moulds a compound microscope is 

 necessary, but much biological work can be done with simple 

 lenses. The choice of food material is not of very great impor- 

 tance, as moulds are found on so many different things — jam, 

 boots, etc. Bread is perhaps more suitable for the purpose and 

 gives excellent results. It should be moistened, then rubbed over 

 a dtisty shelf. In this dust the spores of some of the commonest
