«A wisely chosen illustration is almost essential to fasten the truth upon the ordinary mind, and no teacher can afford to neglect this part of his preparation.»

«Dreams are illustrations... from the book your soul is writing about you.»

«What is character but the determination of incident? What is incident but the illustration of character?»

«GRAVITATION, n. The tendency of all bodies to approach one another with a strength proportion to the quantity of matter they contain --the quantity of matter they contain being ascertained by the strength of their tendency to approach one another. This is a lovely and edifying illustration of how science, having made A the proof of B, makes B the proof of A.»

«HEART, n. An automatic, muscular blood-pump. Figuratively, this useful organ is said to be the esat of emotions and sentiments --a very pretty fancy which, however, is nothing but a survival of a once universal belief. It is now known that the sentiments and emotions reside in the stomach, being evolved from food by chemical action of the gastric fluid. The exact process by which a beefsteak becomes a feeling --tender or not, according to the age of the animal from which it was cut; the successive stages of elaboration through which a caviar sandwich is transmuted to a quaint fancy and reappears as a pungent epigram; the marvelous functional methods of converting a hard-boiled egg into religious contrition, or a cream-puff into a sigh of sensibility --these things have been patiently ascertained by M. Pasteur, and by him expounded with convincing lucidity. (See, also, my monograph, _The Essential Identity of the Spiritual Affections and Certain Intestinal Gases Freed in Digestion_ --4to, 687 pp.) In a scientific work entitled, I believe, _Delectatio Demonorum_ (John Camden Hotton, London, 1873) this view of the sentiments receives a striking illustration; and for further light consult Professor Dam's famous treatise on _Love as a Product of Alimentary Maceration_.»

«LAOCOON, n. A famous piece of antique scripture representing a priest of that name and his two sons in the folds of two enormous serpents. The skill and diligence with which the old man and lads support the serpents and keep them up to their work have been justly regarded as one of the noblest artistic illustrations of the mastery of human intelligence over brute inertia.»

«MAD, adj. Affected with a high degree of intellectual independence; not conforming to standards of thought, speech and action derived by the conformants from study of themselves; at odds with the majority; in short, unusual. It is noteworthy that persons are pronounced mad by officials destitute of evidence that themselves are sane. For illustration, this present (and illustrious) lexicographer is no firmer in the faith of his own sanity than is any inmate of any madhouse in the land; yet for aught he knows to the contrary, instead of the lofty occupation that seems to him to be engaging his powers he may really be beating his hands against the window bars of an asylum and declaring himself Noah Webster, to the innocent delight of many thoughtless spectators.»

«In science, which, being fixed and limited, admits of no other variety than such as arises from new methods of distribution, or new arts of illustration, the necessity of following the traces of our predecessors is indisputably evident; but there app»
