PRITCHARD, Andrew : The Microscopic Cabinet of Select Ani- 

 mated Objects ; witli a Description of the Jewel and Doublet 

 Mici'oscope, Test Objects, &c. : to which are subjoined, 

 Memoirs on the Verification of Microscopic Phenomena, 

 and an exact Method of appreciating the Quality of Mi- 

 croscopes and Engiscopes ; by C. Goring, M.D. The 

 whole work illustrated, from original drawings, by thirteen 

 coloured plates, and numerous engravings on wood. 8vo, 

 pp.246. London, 1832. 185. 



This Vr^ork may be termed a practical treatise on the pre- 

 sent state of microscopes; and supplies, collaterally with this 

 its primary object, 82 pages of description, and ten coloured 

 plates of figures of the aquatic larvae of insects, Crustacea, 

 and animalcules. Some of the subjects in the coloured en- 

 gravings and woodcuts, it is said, have not been previously 

 published in Britain ; and, in the descriptive portion, valuable 

 information is imparted on the structure and habits of these 

 most interesting creatures ; and for procuring, feeding, pre- 

 serving, and the best mode of examining them, useful directions 

 are given. We are warmly desirous of the accumulation of 

 a voluminous body of information, written in as popular, yet 

 able and technically definite, a manner, on all the objects of 

 nature which defy, by their minuteness, elucidation by the 

 application of unassisted vision. All the discoveries hitherto 

 made should be collected, and re-tested, and additional re- 

 searches unremittingly prosecuted ; and, for effecting an object 

 so useful, and importantly serviceable in promoting our know- 

 ledge of nature, perhaps no means will be found so conducive 

 as a Magazine on the Microscope, which should admit con- 

 tributions from all microscopists, and their mutual animadver- 

 sions on each other's researches. Thus would the public be 

 informed of numerous interesting discoveries, which probably 

 now totally escape registry ; and these, from being liable to 

 the close scrutiny and canvass of numerous students and con- 

 tributors, all emulous of excelling each other, would become 

 facts established by the concurrent testimony of competent
