718. Weatherwax, Paul. A method of teaching diffusion and osmosis in connection 

 with biological work. Proc. Indiana Acad. Sci. 1918:88-92. 1920. — The author discusses 

 briefly the history of diffusion and osmosis and then by means of well-known experiments 

 works out definitions. Diffusion, he says, is "the dispersal of the particles of one substance 

 among the particles of another substance, without aid from external sources," while osmosis 

 is "the diffusion of two fluids through a membrane that tends to be semipermeable." The 

 student should be led to connect these processes with the structure of the cell and to realize 

 that all the life processes of the plant that involve exchange of fluids between cell and envir- 

 onment depend upon the selective influence of semipermeable membranes. — F. C. Anderson.
