Introduction to Logic [PDF ebook] 
Designed for the Use of Younger Students

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It would be most presumptuous in a young writer, especially at the present time, to suppose himself capable of advocating new views in Logic, or of introducing any considerable improvement in the system established in this place. No one, how ever, publishes a book, without supposing that it may possibly be of some use; and the following pages were originally composed as an attempt to meet a deficiency which still exists amongst us, the want of a treatise strictly elementary, and adapted to the use of younger students, but entering sufficiently into the principles of the science, to awaken the learners curiosity, and prepare him for a more enlarged and intellectual prosecution of the subject.
