APPENDIX I 

 TABLES RELATING TO STAINS 



In the following tables all the dyes that are frequently mentioned in the literature 

 dealing with microscopic technic are listed, together with the most important uses 

 of each in the biological laboratory. The list of uses (Table 2) is necessarily 

 incomplete. In the case of the most commonly used stains, in particular, it 

 has been necessary to group various uses together under some general term, 

 without attempt to list the individual procedures. In general, however, the policy 

 has been to list the methods for which a stain is most commonly used today, and 

 of the obsolete methods to give only those of historical interest. Criticism will 

 be welcomed from anyone noticing any serious omission. 



The dyes in Tables 1 and 2 are listed in the same order as in the main part of 

 this book. Hence either the general Table of Contents or the list in Table 1 may 

 be used to learn the order of the stains when it is desired to find some particular 

 one in Table 2. For an alphabetical list referring to the following pages see the 

 general Index, 



The references given in the last column of Table 2 refer ordinarily by name and 

 date to the literature listed in Appendix III. Five references, however, are used 

 so often that the date is omitted: they are referred to merely as Chamberlain, Lee, 

 Ehrl. I, Ehrl. II, and Mai. & Wr. These refer respectively to: Chamberlain's 

 Methods in Plant Histology (1924), Lee's Microtomists Vade-mecum (1921), 

 Ehrlich's Enzykopadie der Mikroskopischen Technic (1910), Vol. I and Vol. II, 

 and Mallory and Wright's Pathological Technic (1924). Xo effort has been made 

 to give the original reference in all cases ; but rather to refer to some readily available 

 description of each technic than can be followed by anyone using the procedure.
