CHAPTER VII 

 GENERAL NOTES | 



In my note-book are a number of sugges- 

 tions which may, perchance, be of interest to 

 some of my readers, but could not well be 

 incorporated with any of the preceding chap- 

 ters. Taken at random from its pages, I pre- 

 sent them in collected form, with the hope 

 that they may be useful to a few, at least, 

 which is my excuse for adding them at all. 



Note -Book. I would urge upon all who 

 intend giving serious attention to photo- 

 micrography the great importance of keeping 

 liberal notes of each negative they make, in 

 some clear and simple form.- These should 

 include date of exposure, objective, ocular, 

 condenser, plate, screen, radiant, length of 

 exposure, developer, amplification, etc. It 

 would add still further to the value of such 

 notes if the stain used in making preparations 

 were given also. The note-book should be of 

 ample size and may be ruled to suit the ideas 

 of each worker, or left blank if he prefers. 

 A form shown on the next page is good.
