Our eyes if such they can be called are both microscopes and telescopes, the change in focus being effected as instantaneously as thought, enabling us to perceive the smallest microbe or disease-germ, and to see the planets that revolve about the stars.
Everybody knows how all the arrangements of our telescopes and microscopes are anticipated in the eye, and how our best musical instruments are surpassed by the larynx. But there are some very odd things any anatomist can tell, showing how our recent contrivances are anticipated in the human body.
These small things all added to the huge rolls of fat which it was necessary for him to store up for that "absorptive consumption" which kept him alive during his long winter sleep. This was why Nature had made his little greenish-brown eyes twin microscopes, infallible at distances of a few feet, and almost worthless at a thousand yards.
And yet it will not do to press this assertion too far, for in one sense it is the equipment of the Naples laboratory that has made it what it is. Not, however, the equipment in the sense of microscopes and other working paraphernalia. These, of course, are the best of their kind, but machinery alone does not make a great institution, any more than clothes make the man.
"To be sure it does. But what do you look through?" "The eye-piece." "Well, what is the eye-piece?" "A little glass or two lenses." "These glasses or lenses form a microscope, Tom; and through them you look at the tiny image formed in the focus of the great lens or the speculum, whichever you use." "But I thought microscopes were only used to magnify things invisible to the eye."
"You or anybody else, even with a microscope." "No, of course not. Only you'd say microscopes aren't fair. Well, perhaps they're not. And portrait-painting is a very simple matter. It's not the black art. But if I go on with this, you are to let me do it in my own way. You're not to look at it." "Not even when you're not at work?" "Not once, morning, noon, or night, till I invite you to.
The most brilliant work of Darwin, Kelvin or Edison in no wise alters the fact that there are more things in heaven and earth than are revealed by their microscopes or decomposed in their crucibles. Mental science, and above all moral or ethical science, have a claim to be heard as well as physics.
Indeed the one spark of life in the pathetic old society was its real interest in the antediluvian and prehistoric. For the life that was dead it had a perfect passion, and it sometimes held conversaziones to gaze at it through microscopes. Occasionally it would waken up to literature with a paper on Akenside.
We are shortly to have further particulars concerning this improvement, which, if it be such as described, and applicable to microscopes, will perhaps enable Ehrenberg to verify the opinions he has lately formed concerning the atmosphere namely, that it is not less full of organic and inorganic life than the ocean, or any other part of creation.
It was thus when the discovery that the refraction and dispersion of light did not follow the same law of variation, affected both astronomy and physiology by giving us achromatic telescopes and microscopes. It was thus when Bradley's discovery of the aberration of light enabled him to make the first step towards ascertaining the motions of the stars.
