  DE MORGAN - LoveToKnow Article on DE MORGAN   (Site not responding. Last check: 2007-10-22)
De Morgans writings, however excellent, give little idea of the perspicuity and elegance of his viva voce expositions, which never failed to fix the attention of all who were worthy of hearing him.
De Morgans other principal mathematical works were The Elements of Algebra (1835), a valuable but somewhat dry elementary treatise; the Essay on Probcfbilities (5838), forming the io7th volume of Lardners Cyclopaedia, which forms a valuable introduction to the subject; and The Elements of Trigonometry and Trigonometrical Analysis, preliminary to the Differential Calculus (5837).
In 1860 De Morgan endeavoured to render their contents better known by publishing a Syllabus of a Proposed System of Logic, from which may be obtained a good idea of his symbolic system, but the more readable and interesting discussions contained in the memoirs are of necessity omitted.

De Morgan’s "laws," "rules" or "theorems" are, of course, merely logical equivalences and should always be identified as such.
