ARE WHITE WORMS INJURIOUS ? 
BY REV. HILDERIC FRIEND. 
During the past year, while engaged in the study of 
Enchytraeid Economics in the Department of Zoology, 
under the direction of Professor Gamble, f.r.s., at Birming- 
ham University, I have had occasion to examine the 
communications which took place some years ago between 
myself and a number of Irish correspondents. In looking 
over the letters received, I have been somewhat surprised 
to find how many of them had reference to the existence of 
white worms (Enchytraeids) at the roots of decaying plants. 
Unfortunately I did not keep a copy of my replies, and in 
some instances I do not even possess a memorandum to show 
what particular species of worm was discovered in the 
material examined. It is possible, however, to bring 
together a sufficient body of evidence to shew that Enchy- 
traeids were liable to serious suspicion, and I purpose in 
this article to summarize that evidence in the hope that it 
may lead to further correspondence, and the final solution 
of the problem. These notes relate solely to Ireland.
