The entire panorama from the latter point, taken with the camera lucida, along with copies of some daguerreotypes made at the same place, are herewith submitted. Of the part of the line which extends to the northeast from the source of the Etchemin for a distance of many miles, a view may be almost constantly seen from the citadel of Quebec and from the tops of the houses in that city.
His chamber also bears evidence of his various avocations; there are half copied sheets of music; designs for needlework; sketches of landscapes, very indifferently executed; a camera lucida; a magic lantern, for which he is endeavouring to paint glasses; in a word, it is the cabinet of a man of many accomplishments, who knows a little of everything, and does nothing well.
I went into Fleet Street one Sunday morning last November with my camera lucida to see whether I should like to make a sketch of the gap made by the demolition of the Cock Tavern. It was rather pretty, with an old roof or two behind and scaffolding about and torn paper hanging to an exposed party-wall and old fireplaces and so on, but it was not very much out of the way.
Lubbock made drawings for me with the camera lucida of the jaws which I had dissected from the workers of the several sizes.
A similar effect was noted December 1, 1811, when the great comet of that year approached so close to Altair, the lucida of the Eagle, that the star seemed to be transformed into the nucleus of the comet. Even the central blaze of Halley's comet in 1835 was powerless to impede the passage of stellar rays. In neither case was there any appreciable diminution of the star's light.
Along with this I purchased every possible accessory draw-tubes, micrometers, a camera lucida, lever-stage, achromatic condensers, white cloud illuminators, prisms, parabolic condensers, polarizing apparatus, forceps, aquatic boxes, fishing-tubes, with a host of other articles, all of which would have been useful in the hands of an experienced microscopist, but, as I afterward discovered, were not of the slightest present value to me.
Yet the night is far from dark. The forests and the mountain-bulk beyond the valley loom softly large and just distinguishable through a pearly haze. The path is purest trackless whiteness, almost dazzling though it has no light. This was what Dante felt when he reached the lunar sphere: Parova a me, che nube ne coprisse Lucida, spessa, solida e pulita.
"I trust that this is true, and that Apollo will not seem jealous. If I return in triumph, I will offer him such a hecatomb as no god has had so far." Scevinus fell to repeating the lines of Horace: "Sic te diva potens Cypri, Sic fratres Helenæ, lucida sidera, Ventorumque regat Pater-" "The vessel is ready at Naples," said Cæsar. "I should like to go even tomorrow."
In each hut was arranged a camera lucida, so that a picture of the harbor, over a limited area, was thrown upon a whitened table. In this way an observer could recognize the instant an enemy's vessel arrived over a sunken mine, and could explode the latter by simply touching a button which allowed the electric current to pass to the torpedo.
I speak confidently on this latter point, as Sir J. Lubbock made drawings for me, with the camera lucida, of the jaws which I dissected from the workers of the several sizes. Mr. Bates, in his interesting "Naturalist on the Amazons," has described analogous cases.
