There have been aay books, — osed, some of them, by very able 
authors, in which the reasoning wa s barely indicated ; the leading steps

compel his pupils S. petiy that which is wanting in the text-book. 
For whatever, in this respect, may be the character of the text-book, it 
is clearly most important for the pupil in his recitations, that he should 
be accustomed to a very full development. He should not be allowed 
to skim lightly and sketchily over his-work. He should be taught to 
notice and examine every point which is really essential to the conclu- 
Salinas of his reasoning. He should be guarded against the common 
habit of taking for granted without further proof, that which appears 
plausible or probable upon its nase The great advantages, which are 
expected from the elementary study of mathematics, as a means of 
mental discipline,—the siesmnaal of thought, correctness of reasoning 
and precision of statements, which are supposed to be imparted by 
mathematical study,—are liable to be more or less completely sacri- 
ficed, unless the student is trained in the outset of his course to thorough, 
copious and accurate development. It is therefore a matter of no 
small importance that he should have a a of this quality constantly 
before him in the text-Look which he studies. And in this particular,
