organism, so corresponds with its qualities and attri- 

 butes, that its mentality is clearly allied to its physi- 

 cal features. How much more interesting are the 

 antics and movements of a chimpanzee, than those of 

 a sloth; of ants and bees, than those of a snail, or 

 worm. The forms of all these are perfectly adapted 

 to their psychical manifestations. In the same man- 

 ner man, standing erect, with arms and hands free, to 

 seize upon matter, and mold it as he chooses with a far 

 range to his vision, because he does stand erect, has 

 also a mind corresponding to his shape, in its free 

 choice of many methods open to him to use his supe- 

 rior vision, and his free, well formed hands; while his 

 nearest brother in the animal kingdom, the orang- 

 outang, not being able to maintain the upright position, 

 and not having free hands, is also, low in his methods 

 of mental action. Yet, the man and the monkey, as 

 said above, are very much alike in anatomy, and differ 

 in psychical action, only in degree, not in kind. The 

 chief difference between the vegetable, and the animal 

 forms, is that the cells of the former are bound in a 

 sac, the walls of which are composed of cellulose. The 

 nature of cellulose in its character, as a binder, to pre- 

 vent freedom of action, such as an animal exhibits, is 

 best illustrated, by saying, that cotton, and the 

 bleached fibre of flax and hemp, are nearly pure cellu- 

 lose. The animal could not have its peculiar charac- 

 teristics, if cellulose covered each cell of the body. 



DEVELOPMENT OP AN EMBRYO. One of the most 

 beautiful and wonderful phenomena of nature is the 

 development of the embryo of an organism. From 

 the moment of fertilization to the maturity of the form, 

 it unfolds in the most marvelous manner, as if the deli- 

 cate touch of an artist's fingers was molding it into
