 which a pole maybe readily pushed for a depth of six feet. 

 When withdrawn, the soft mud is scraped off and subjected to 

 the usual treatment for the removal and concentration of 

 diatoms. 



"This mud proved to be of unusual richness in variety of 

 micro-organic remains, as may be attested by an examination 

 of the slides prepared from the same. Associated together may 

 be found marine and fresh-water species of diatoms, several 

 interesting varieties of sponge spicules, very numerous tests or 

 carapaces of fresh-water rhizopods, and several species of marine 

 foraminifera. Also there may be seen varieties of pollen grains 

 or spore capsules, many plates of mica, and of less interest the 

 tissues of plants of a partially siliceous nature — P hytolitharia 

 (Ehrenberg). 



" I have prepared, in a probably unusual manner, a set of four
