The Secretary read, in behalf of Dr. W. I. Burnett, a

 tion of a parasitical animal from the intestinal canal of 

 Ants, as follows: 



Some time ago, (see " Journal," Vol. VI. Art. XIX.) I presented 

 to the Society a communication on the intimate character of the 

 genus Bodo, a parasitic infusorium, found pretty constantly in 

 the intestinal canal of many reptiles, and that of the frog, in

 the question of the real position of such animal-like bodies in 

 the organized world. 



Since that time, repeated studies in this direction, and many 

 explorations along the very confines of animal life, with very 

 high and excellent magnifying powers, have urgently presented 

 this question to my mind, and under various aspects. Its great
