graphing required considerable time for its develop- 

 ment, and much experimenting with chemicals and 

 apparatus.

 the Author not being the owner of any that could be 

 fairly classed as such, obtained the cooperation of 

 Mr. Stanford, who owned a fine stud of horses at his

The apparatus used at this stage of the inves-

 arrangement of which will be described further on. 



Some of the results of these early experiments which

 journals of the day.
