This would have involved considerable extra cost, and more over such references are usually neglected by students in a first study of the subject, in our opinion wisely so.<br><br>In a second reading, however, works of reference should a 3recommended in the first place 18 intermediate between text-book and descriptions of original research, namely, a résumé on some special section of subject matter.
