Sinopsis
Excerpt from First Notions of Logic: Preparatory to the Study of Geometry
Moreover, the negative words not, no, &c., have two kinds of mean ing which must be carefully distinguished. Sometimes they deny, and nothing more: sometimes they are used to affirm the direct contrary. In cases which ofi'er but two alternatives, one of which is necessary, these amount to the same thing, since the denial of one, and the affirm ation of the other, are obviously equivalent propositions. In many idioms of conversation, the negative implies affirmation of the contrary in cases which offer not only alternatives, but degrees of alternatives. Thus, to the question, Is he tall?' the simple answer, No,' most frequently means that he is the contrary of tall, or considerably under the average] But it must be remembered, that, in all logical reasoning, the negation is simply negation, and nothing more, never implying affirmation of the contrary.

Excerpt from First Notions of Logic: Preparatory to the Study of Geometry
This Tract contains no more than the author has found, from experience, to be much wanted by students who are commencing with Euclid. It will ultimately form an Appendix to his Treatise on Arithmetic.
The author would not, by any means, in presenting the minimum necessary for a particular purpose, be held to imply that he has given enough of the subject for all the ends of education. He has long regretted the neglect of logic; a science, the study of which would shew many of its opponents that the light esteem in which they hold it arises from those habits of inference which thrive best in its absence. He strongly recommends any student to whom this tract may be the first introduction of the subject, to pursue it to a much greater extent.
