12 The Microscope. 



All the granules were on tremble there below! 

 Then a current like a river, 

 Taking pebbles in its way, 

 Could be traced along the center in its flow. 



When did it commence? we queried, 

 Was the fluid there the same, 

 Flowing from the nucleus outward to return? 

 . While we gazed till eyes were wearied, 

 Changing focus, mirror, flame, 

 Seeing all and yet unable to discern? 



In the more ethereal presence, 



Where the deep emotions dwell, 

 There may be an outward current ere we know; 

 And some moment of quiescence 

 May reveal its tidal swell, 

 Like the ripple of the protoplasmic flow.

RESULTS OF MICROSCOPICAL RESEARCH. 



Mounts of Fresii-water Alg/e. — A writer, under the ini- 

 tials of W. A. W., relates his experience in the Microscopical 

 News (iv, 216, 1884) in attempting to make permanent mounts 

 of fresh-water algae. He comes to the conclusion that the best 

 medium is water to which a slight amount of camphor water has 

 been added to prevent the growth of fungoid and algoid organ- 

 isms. One of the difficulties usually experienced is in the lading 

 of the chlorophyll, and this W. A. W. would try to prevent by 

 boiling the water so as to expel the air and using it before it has 

 had a chance to absorb more oxygen from the atmosphere. 

 The influence of light is also injurious and hence the slide should 

 be kept in a dark place. 



Development op Fishes. — Mr. Geo. Brook, Jr., has been 

 studying the development of Motella and finds that there is an 

 embryonic cranial flexure and a ventral mouth analagous with 

 those so characteristic of the sharks and skates.
