The reader will notice that the aberrations produced at a very low temperature (from 0 to -20 deg C.) are absolutely identical with the aberrations produced by exposing the pupae to extremely high temperatures (42 to 46 deg C.). Moreover the aberrations produced by a moderately low temperature (from 0 to 10 deg C.) are identical with the aberrations produced by a moderately high temperature (36 to 41 deg C.)英文原著 · 《Darwin and Modern Science》

Spherical aberration is overcome by proper care in the formation of the lens: "It can be shown upon mathematical data that a lens similar to that given in the following diagram--one surface of which is a section of an ellipse, and the other of a circle struck from the furthest of the two foci of that ellipse--produces no aberration.英文原著 · 《American Hand Book of the Daguerreotype》
It is simply the aberration of a rather remarkable lunatic. It is no good; it is not worth the price of a cheese sandwich. I understand that its one feat has been to break your leg; if it ever goes off again, persuade it to break your neck. And now I want you to take this nursery rhyme of yours and get out. And don't ever come here again. Do You understand ? You understand, do you ?" He arose and bowed in courteous dismissal.英文原著 · 《Active Service》
"At the earliest period of the employment of the camera obscura, a double-convex lens was used to produce the image; but this form was soon abandoned, on account of the spherical aberration so caused. Lenses for the photographic camera are now always ground of a concavo-convex form,英文原著 · 《American Hand Book of the Daguerreotype》
