Dr Goring and Mr Pritchard's Treatise on the Microscope, ^b^ 



suit would be five hundred different systems of hypotheses, each of which 

 would be constructed to suit the facts that took the deepest hold of the au- 

 thor's mind ; but science would gain nothing by all this display of inge- 

 nuity or of knowledge. Nature would still be found in her strongholds, 

 with her mysteries veiled, and her treasures unlocked- We would there- 

 fore strongly recommend it to Mr Exley, to devote his time and his talents 

 to the prosecution of some department of science where the study of facts, 

 and the investigation of their cause, will, we doubt not, place him among 

 those men who have advanced the genuine interests of science, and have 

 established for themselves an imperishable monument in the temple of 

 fame. 



IF. The Natural History of several new popular, and diverting living ob- 

 jects for the Microscope, with the phenomena presented by them under ob- 

 servation, S^c. Conjoined with accurate descriptions of the latest improve- 

 ments in the Diamond, Sapphire, Aplanatic, and Amician Microscopes : 

 And Instructions for managing them, S^c. S^c. To which is added a Tract 

 on the newly discovered Test objects. Illustrated by highly finished co- 

 loured Engravings from Drawings of the actual living subjects. By 

 C. Pi. Goring, M. D. and Andrew Pritchard. No. II. pp. 64 with 

 three Plates. 



Having already given an account of the first Number of this valuable 

 work, and stated our opinion of the high qualifications of Dr Goring and 

 Mr Pritchard, for so diflicult an undertaking, we shall proceed, without 

 any farther preface, to the analysis of this new Number, which consists of 

 the following Chapters and Sections : — 



Chap. IV. — Whether there is a best possible way of constructing the 

 stand or mounting, &c. of Microscopes, (the specific purpose or purposes 

 to which they are to be applied being first determined.) 



Chap. V. — Description of an operative Aplanatic Engiscope, (Micro- 

 scope.) 



Chap. VI. — Manner of observing with, and managing the operative 

 Aplanatic Engiscope. 



isf. Manner of mounting, for viewing inanimate transparent objects, 

 by pure intercepted day-light. 



2c?, Manner of mounting for viewing transparent objects by artificial 

 light. 



3c?, jVTode of mounting for viewing diaphanous bodies by reflected day- 

 light, either in a horizontal or vertical position. 



^th. Way of mounting for transparent living bodies. 



6th, Method of mounting the diamond or sapphire microscopes for 

 transparent objects. 



Qth, Method of observing opaque objects by day-light, plain or con- 

 densed. 



11 th. Method of observing opaque objects by artificial light, either plain, 

 condensed, or reverberated by silver cups.
