larg-e adult male, weighed just 17 grammes. No sooner did the 

 Shrew become aware of the presence of the mouse than he gave 

 chase. The mouse, thouofh much laro-er than the Shrew, showed no 

 disposition to fight, and his superior agility enabled him, for a long 

 time, easily to evade his pursuer, for at a single leap he would pass 

 over the latter's head and to a considerable distance beyond. The 

 Shrew labored at great disadvantage, not only from his inabilit)- to 

 keep pace with the mouse, but also, and to a still greater extent, 

 from his defective eyesight. He frequently passed within two inches 

 (31 mm.) of the mouse without knowing of his whereabouts. But 

 he was persistent, and explored over and over again every part ot

 the Shrew had no difficulty in keeping alongside, and soon had him

 to no avail. The Shrew was evidently much pleased and forthwith 

 began to devour the ear. When he had it about half eaten -off the 

 mouse again tore himself free ; but his inveterate little foe did not 

 suffer him to escape. This time the Shrew clambered up over his 

 back and was soon at work consuming the remainder of the ear. 

 This being satisfactorily accomplished, he continued to push on in 

 the same direction till he had cut through the skull and eaten the 

 brains, together with the whole side of the head and part of the 

 shoulder. This completed his first meal, which occupied not quite
