ILLUSTRATING THE 



WONDERS OF THE MINUTE CREATION ; 



WITH 



Scs"m|)ttan$ at the Ohjerte, 



BY ANDREW PRITCHARD. 



1 By the beauty of the creatures, proportionably, the mightiness of the Maker of them 

 is seen." — Wisdom of Solomon. 



The design of this Work is an attempt to elucidate those parts of the creation, 

 which from their extreme minuteness are known to us only by the aid of the Micro- 

 scope. So manifold and various are these productions, all equally wonderful and 

 beautiful in their kind, and alike indicative of the wisdom and power of " the Maker 

 of them" — so full of interest is the study of them, that there is no branch of Natural 

 Philosophy to which our attention may be directed with a greater promise of instruc- 

 tion and delight. 



Whilst the press absolutely teems 'with Works explanatory of organic and inorganic- 

 bodies, might we not expect, that the Illustrations of these Works would chiefly result 

 from the personal observations of the Authors ? Such, however, is not the case. 

 Strange to say, they are chiefly copies. A series of original Drawings, therefore, illus- 

 trating a Work of this description, taken from the finest specimens of Microscopic 

 objects ; such as the minute structures of the animal creation — the respiratory apparatus 

 and various locomotive, manducatory, visual, natatory, and other organs of Insects 

 — portions of bone, skin, scales, &c, &c. — the structures of woods, plants, recent and 

 fossil, ferns, mosses, algae ; also, the manner in which the circulation is carried on within 

 them — the curious mode of aggregation in divers geological productions; and a mul- 

 tiplicity of other highly interesting matters, it is thought, will not be unacceptable to 

 the public. 



From the number of years the Author has been occupied collecting his materials, 

 and the thousands of beautiful preparations which have passed through his hands, no 

 ordinary opportunity has been afforded him; and it is with this belief, that he now 

 comes forward with a Work on this branch of Natural Philosophy.
