One Thousand Objects 



FOR 



THE MICROSCOPE. 



v HE classification of objects adopted in this work is 

 \ the primary division into two nearly equal sections, 

 of which the first contains objects derived from the Vege- 

 table kingdom, or Plant world, and the second of objects 

 obtained from the Animal kingdom. Naturally enough, 

 the first section subdivides itself into two groups, the one 

 including derivatives from Phanerogamic or Flowering 

 plants, and the other Cryptogamic or Flowerless plants, 

 such as ferns, mosses, fungi, and water-weeds or algcz. The 

 first group, or those objects which are derived from flower- 

 ing plants, such as trees, shrubs, garden and wild flowers 

 or weeds, contain the elementary tissues and the organs of 

 plants. A general and popular arrangement, under a few 

 groups, has been adopted in preference to a rigid scien- 

 tific sequence, which would have assumed the reader to 

 be in possession of considerable technical knowledge, an 

 assumption by no means consistent with the design of the 

 present work. 



In examining the objects enumerated, we may be per- 

 mitted to recommend the novice always to commence the 

 examination with the lowest power of his microscope, and 

 then, where necessary, to proceed with the higher powers. 

 It is well never to commence the examination of an object
