THE PRESIDENTIAL ADDRESS. 221 where food, i.e. earthworms, are likely to be abundant. The stream near Theydon Bois where the specimens were found appears to be contaminated to some extent with effluent from a neighbouring farm. Since the above was written, Mr. Bostock paid another visit to the locality and took eight specimens of the leech—five adults and three immature.
