CHAPTER XXI II 

 LITERATURE OF THE MICROSCOPE 



Books and Papers. — Books on the microscope can mostly 

 be divided into books for beginners, books (and original 

 papers) on high-power work, and books (and papers) on 

 the theory of the microscope. The articles in the Journal 

 of the Royal Microscopical Society and the Zeitschrift fuer 

 wissenschaftliche Mikroskopie are often more instructive 

 than any books, being usually first hand; while much of 

 most books must necessarily be second hand. The 

 advanced mathematics of the microscope, however, is 

 mostly of interest only to the calculators of new objectives. 

 The voluminous literature on the objects seen with the 

 microscope, and the excellent manuals of methods for 

 preparing objects, such as Bolles Lee's ''Vademecum," for 

 animal, and Chamberlain's manual, for plant preparations, 

 are not under consideration here. 



Books for Beginners. — E. Bausch's few pages (26) on 

 how to use the microscope are trustworthy, and have no 

 doubt been useful to many when making their first 

 acquaintance with the instrument, and will be useful to 

 many more. The same may be said of the excellent book- 

 lets of instructions published by C. Zeiss, the vSpencer 

 Lens Company, Watson and Sons, and E. Leitz. The 

 first volume of C. Beck's book on the microscope (30) 

 contains a handy account of the microscope, suitable for 

 those beginning to use one. It includes some practical 

 hints. The booklet by Ehringhaus (63) was recommended 

 by Erfle as a convenient introduction to microscopy. It 

 is an accurate account of the modern microscope and its 

 accessories, but contains little practical matter. Gage's 

 well-known book on the microscope (66), now in its four- 

 teenth edition, contains an elementary account of the
