ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 863 



will enable those who are new to the subject to master it more readily 

 and satisfactorily than they could do by the more usual mode of 

 treatment adopted in the ordinary text books. 



The phenomena of polarization occupy 143 out of the 358 pages 

 of the text, and this section is illustrated by 62 figs, and 6 plates, 2 of 

 which are beautifully coloured. There is an Appendix on ' Dif- 

 fraction in the Microscope,' condensed from this Journal, I. (1881) 

 pp. 350-5.
