TISSUE FLUIDS OF DESERT LORANTHACE^E. 3 



in Table II. This shows that electrical conductivity, like freezing- 

 point lowering, and the ratio K/& is higher in parasite than in host. 



Thus it appears that there is some mechanism not as yet 

 determined by which the mistletoe accumulates and retains in 

 solution larger quantities of dissociated salts or organic acids 

 than does the host. 



It is possible that higher transpiration from the parasite 

 might result in the accumulation in a purely mechanical manner of 

 larger amounts of salts from the transpiration stream, but this is 

 merely a suggestion requiring further investigation.
