Chamberlain's Methods In Plant Histologry'^ 



During the fifteen years which have elapsed since its initial 

 appearance, Chamberlain's "Methods in Plant Histology" has 

 come to be generally regarded as an almost indispensable part 

 of every teaching botanist's equipment. The first edition 

 (1901), followed four years later (1905) by a second, has now been 

 superseded by a third. This volume follows the same general 

 scheme as the second edition. In Part I (pp. 1-147) the prin- 

 ciples and methods of technique have been described in a general 

 way. As before, there are chapters on apparatus, reagents, 

 stains and staining, temporary mounts and microchemical tests, 

 freehand sections, the glycerin method, the Venetian turpentine 

 method, the paraffin method, the celloidin method, and special 

 methods, while a new chapter has been added on photomicro- 

 graphy and lantern slides. Part II (pp. 151-307) is devoted 

 mainly to the application to specific cases of the methods evolved 

 in Part I. In addition, attention is given to the collection of 

 material, its cultivation to secure reproductive phases, etc. 



Although the general plan of this volume is identical with that 

 of the preceding editions, it is virtually a new book. The subject 

 matter has been thoroughly revised and brought up to date and 

 has been largely rewritten. The number of pages in the present 

 volume is fifty pages greater than that in the second edition.
