CHAPTER II. 



GENERAL OBSERVATIONS ON THE CATALOGUE OF 

 MICROSCOPIC OBJECTS. 



Animal. — Under this head are comprised objects ob- 

 tained from the animal kingdom, whether recent or fossil, 

 including the Corallines, Sponges, and Zoophytes. In 

 general, the names are placed alphabetically ; but where 

 there is a considerable number of one kind, they are 

 placed under separate heads. These divisions are not 

 intended as systematic, but rather as illustrative of dif- 

 ferent forms of organization for effecting similar pui'poses. 

 Thus, imder the head of Feet are included those not only 

 of Insects, but of Arachnida, &c. The same remark will 

 apply to the other divisions. 



It must be borne in mind that this little work is not 

 intended to instruct the entomologist in the arrangement 

 or technicalities of his science, nor the botanist in the cha- 

 racter of plants. But the general observer of nature, in 

 every department, will find fragments of materials scat- 

 tered throughout, that, it is believed, will assist him in 

 any branch of natural science that he may be disposed to 

 cultivate.
