Bailey from Mr. Tuomey, specimens were sent to Prof. Ehren- 

 berg, the celebrated German Naturalist, and Jby him distrib- 

 uted among the leading microscopists of the world. 



The Nottingham specimens appear to be the same as the 

 infusorial earths from the Rappahannock, with the exception, 

 principally, that the Actinocyclus and some other forms in 

 the latter, are replaced by the beautiful Heliopelta in the

 various fruits now engaging the attention of the horticul-

The Chair exhibited a rose, from the center of which a

 on the plants collected during the day, read the following

The Creator has placed on the earth many races of sentient 

 beings of high order, and these with such a structure and

 upon the presence of another class of organized life, wholly 

 distinct in characters from the first. This latter, feeding on 

 the store of mineral and gaseous material around, is ever 

 made to prepare, by assimilation, the aliment of those higher 

 creatures known as animals. Thus these intermediate struc-
