1 For the original of these passages we refer the scholar to that admirable letter of Bacon’s, De mirabile potestate artis et naturae, etc., which appeared first of all in the work of Claudius Celestinus, De his quae mundo mirabiliter eveniunt, Lutetiae Parisiorum, 1542. Bacon’s description of a flying machine, of which we read in the same document, shows, however, that he too, in his philosophical visions, was apt to transgress the line of the possibilities. ↑
2 At the end of the nineteenth century the Saxon element had almost entirely disappeared from the English tongue; even the most intelligible Norman words had had to give way to the most miraculous novelties in the shape of bad Greek and Latin compounds. At the revival of the genuine national dialect all such abominable mongrels as telegram, bicycle, velocipede, etc., were expelled from decent conversation. A telegram became a wire-message; a bicycle a two-wheel; a velocipede a swift-foot; post-mortem examinations went by the name of after-death examinations; and as the language gained in nationality, the nation’s mind grew in clearness. The change was a change for the better.

3 The camera obscura (dark chamber) is a closed space impervious to light. Porta, the inventor here referred to, was a Neapolitan physician. He found that by fixing a double convex lens in the aperture, and placing a white screen in the focus, the image was much brighter and more definite.

4 Galvani was a professor of anatomy in the university of Bologna. While engaged in his anatomical investigations he observed, accidently so to say, that when the lumbar nerves of a dead frog were connected with the crural muscles by a metallic circuit, the latter became briskly contracted. The electricity theory drawn by Galvani from his observation of the frog was chiefly opposed by the philosopher likewise here mentioned, Alexander Volta, professor of physics in Pavia.

5 Oerstedt’s discovery, published in the year 1819, was afterwards considerably extended by Ampère and Faraday. It laid, however, the foundation of the recognition by science of the relations between magnetism and electricity.

6 Nor did La Condamine probably suspect that the small bottle of india-rubber, which he brought with him on his return from a scientific tour to America, and passed round as a curiosity to his colleagues of the French academy, was actually filled with a liquid destined to become of the most extensive application to different branches of industry; aye, a liquid without which the submarine telegraph would simply have remained an impossibility up to the present day. ↑

8 The truth of this remark cannot, I think, be sufficiently impressed upon the even now existing opposition minority in England. Let us have compulsory education for three, or even two, generations, and every citizen in the state will be so well educated himself as to know the value of education, and not to deny it his children. The repeal of any law, prohibitory or compulsory, can only prove this, that the people for whom the measure was originally framed have risen in the scale of moral and social organization.

9 Like the ingenious author of the “Origin of Species,” Miss Phantasia appears to have convinced herself that the time would come when the absence or rarity of intermediate species, the great stumbling-block in the grand Darwinian theory, would no longer have to be accounted for negatively by the “poorness of our palæontalogical collections,” and the “imperfectness of the genealogical record.” Bacon, though apparently familiar with, and not averse to, Mr. Darwin’s theory of evolution, does not seem to follow the doctrine out in its application to the human race. How many errors remain to be eradicated, even in minds of the highest order, through man’s adopted notion that he stands exclusively apart from all his natural surroundings, both in degree and in kind!

10 It is but fair to say that the apparatus of Léon Scott for registering the vibrations produced by the voice in singing had preceded the discovery of Reis. Scott’s “phonautograph” is fully described, both in construction and working, in Ganot’s Treatise on Physics (Atkinson’s translation, p. 211, etc.)

11 It is embarrassing to render the original German coinage humanität, which, we believe, is due to the grand idea of Lessing, but it is a decided fallacy, current even among literati, that the absence of a certain word in a certain language indicates the absence of the idea embodied in the word among the nations by whom that language is spoken. This vulgar error, the prolific source of so many idle boasts, and unjust charges, and national vanities, we have endeavoured to refute in a paper on “The Philosophy of Verbal Monopoly,” printed in the “Transactions of the Devonshire Association for the Advancement of Art, Science, and Literature,” 1868.

12 So little do we know of a country so worth knowing, that we daily commit ourselves by speaking of it as Holland. The kingdom of the Netherlands, as now constituted, is divided into ten counties or provinces, and two of these are respectively called North and South Holland. The former is the territory here alluded to; it includes neither Leiden, nor the Hague, nor Rotterdam. To speak of the Netherlands as Holland, corresponds to calling England Devonshire or Cheshire, and this particular terminology is the more amusing to the natives because with them it is a shibboleth of vulgarity. There never was a kingdom of Holland, except from 1806–1810, under Napoleonic rule, when the Dutch had lost their independence through that most dangerous scourge of nations, internal division.

13 The Dutch adopted the metric system for weights and measures simultaneously with the French; that is to say, at the close of the eighteenth century. Their meter is little more than three English feet.

14 In order to make this allusion to Rotterdam intelligible to our English readers, we have to state a few facts. While Rotterdam has an excellent harbour, Amsterdam has not. From time to time the citizens of the latter city have devised all kinds of means whereby to remedy the natural disadvantage under which they labour. There is no lack of petty jealousies between the two great rival commercial cities of the Netherlands, and hence the allusion of dramatic rejoicings in Rotterdam at the misfortune of the competitor.

15 Although most of these speculations on university education would appear to apply to the author’s own country, it cannot be denied by any one at all acquainted with the English seats of learning, that the whole is an unconscious but delightful bit of satire on the working and results of both Oxford and Cambridge.
