“It has been a leading object in its compositio t to anticipate the 
student’s acquirements, but to carry him forward, the wey step, in a series 
of consecutive propositions. To aid him as much as possible in applying 
the knowledge already acquired, the paragraphs have been numbered and 
constant reference has been made throughout the work to previous sec-
