 tlie two latter kinds, especially those of the 

 carrot, were preferred to all the others, 

 including those of celery. It was also mani- 

 fest after many trials that wild cherry leaves 

 were greatly preferred to those of the lime- 

 tree and hazel (Corylus). According to Mr. 

 Bridgman the "half-decayed leaves of Pldox 

 verna are particularly liked by worms.* 



Pieces of the leaves of cabbage, turnip, 

 horse-radish and onion were left on the pots 

 during 22 days, and were all attacked and 

 had to be renewed ; but during the whole 

 of this time leaves of an Artemisia and of 

 the culinary sage, thyme and mint, mingled 

 with the above leaves, were quite neglected 

 excepting those of the mint, which were occa- 

 sionally and very slightly nibbled. These 

 latter four kinds of leaves do not differ in 

 texture in a manner which could make them 

 disagreeable to worms ; they all have a strong 

 taste, but so have the four first mentioned 

 kinds of leaves; and the wide difference in 

 the result must be attributed to a preference 

 .i;y the worms for one taste over another,
