An interesting note made on this experiment is as follows : 



" The soil in which the pipe was buried was loamy, and when 



diffoine 1 the trench no worms were noticed, but towards the conclu- 



oo o 



sion of the experiment it was observed that hundreds of worms came 

 to the surface between 3 ft. and 9 ft. on either side of the pipe ; no 

 worms appeared, however, immediately over, the pipe."
