 Par eh. Kobin, Meiubre de I'lnstitut (Acadi'mie des Sciences) et de

 Many works as we have in our language upon the microscope, and 

 manifold as are the instruments described, the apparatus men- 

 tioned, and the tissues displayed, it is nevertheless a fact that there is 

 in the English language no book which deals more with the subject 

 of human anatomy than with those of the comj)arative branches of 

 histology. Doubtless this is because those who devoted themselves 

 to the subject of comparative anatomy were so much more numerous 

 than the students of, let us say, hmnan histology. Hence, doubtless, 

 the reason why in such admirable works as those of Dr. Carj)enter, 

 Dr. Beale, and Mr. Hogg, much relating to the human microscopic 

 anatomy has been omitted to make room for facts in the anatomy of 

 Protozoa, Coelenterata. Annulosa, and Mollusca. 'Tis true that Dr. 

 Beale's work enters more upon human histology than either of the 

 others, but then he does not go fully into the subject for the very 

 natural reason that those who piu'sue it are vastly fewer than 

 those who delight in the study of Eotifera and Infusoria. Of course 

 we do not refer to Dr. Richardson's American work, for it deals with 

 human anatomy almost exclusively, and fui-thermore it is small in 

 extent of pages, and is almost devoid of illustration. There is there- 

 fore room for such a work as the present one, which attempts to deal 

 T\nth the whole of microscopy, and wldch does fair justice to each of 

 the departments it takes in hand. 



The work now before us is a large 8vo volume of more than 1000 

 pages, and with over 200 woodcuts, besides three or four plates 

 at the end. It is divided into three parts. The first deals with the 

 subject of injections ; the second part treats of the various forms of 

 microscope constructed in France, England, &c., &c. ; next it deals 

 with the instruments and apparatus to be employed in the pro- 

 duction of cells and the general mounting of microscopic objects, the 

 making of sections, the chemical agents employed in microscopy, 

 the modes of using the microscope, and of reflecting the light from 

 the mirror, &c. The third and last part, which forms about half the 

 volume, was, we may say, almost absent from the work which 

 appeared in 1849, and hence the present volume may be looked upon 

 as a comparatively new treatise. It deals with the ai)plication of 

 the microscope, and its auxiliaries to anatomy, physiology, medicine, 

 animal and vegetable natural history, chemistry, and agricultural 

 economy. It is this part of the volume which, in our opinion, gives 

 it a siiecial character, and helps to add to our information facts which 

 do not exist in any of the English works already noticed. 



The opening chapter deals with the subject of injection, and goes 

 into the question very fully. The author gives a preference to Dr.
