 making their way towards the sides of the vessel, and others to 

 the surface, from which they may be easily picked up. The 

 material may be occasionally stirred up, which will cause a new 

 series to appear. This process may be repeated with success for a 

 day or two. When the water has even become offensive, and 

 many of the animals have died, a few may still be found on the 

 surface, which do not appear at an earlier time. 



Collecting Vessels. — These need not be noticed particularly here, 

 as their form, size, and number will always depend on what 

 objects are chiefly intended to be secured. A pail, three or four 

 glass pickle bottles, a few phials and glass tubes for small things, 

 a white saucer to examine them in, and a hair pencil to pick up 

 minute objects, will go far to meet all wants in ordinary cases.
