I well remember the visit I received from my dear friend Warren de la Rue in the year 1840. I was executing some work for him with respect to a new process which he had contrived for the production of white lead. I was then busy with the casting of my thirteen-inch speculum. He watched my proceedings with earnest interest and most careful attention.
The aurora borealis stands as the emblem for the magnetic attraction of Earth on spirit, the Christ soon to be born in the manger of the Goat; the descent of the Holy Ghost into material form, so that heavenly truth may illumine the drear speculum of earthly thought with the Divine iridescence of celestial light.
She was supposed to have dropsy of the abdomen, and among other treatments was the use of a speculum and caustic applications for inflammation of the womb. The escape of watery fluid for two days was considered evidence of the rupture of an ovarian cyst. At the end of two days, severe pains set in, and a warm hip-bath and an opiate were ordered.

"That was some 'un artful, sir, and he got in." "Slipped in descending inside, and dragged the speculum on the floor," said Uncle Richard, frowning. "Now the question is, who was it?" "Ah, who was it, sir?" said David. "Arn't such a great many folk in Furzebrough, and I should say as it lies between Parson Maxted and Pete Warboys, and it warn't parson, 'cause of the boots."
"Think we shall polish out all the scratchings?" "Why, they are gone now," cried Tom. "Yes, it shows what patience will do," said Uncle Richard; "a man can't lift a house all at once, but he could do it a brick at a time." The speculum was carefully placed aside after its cleansing, and the pair of amateur opticians locked up the place after hanging up their aprons.
And the Little Picture of the Sun, that appear'd upon the White Marble as a Speculum, was but very Faint and exceeding ill Defin'd.
"Then you couldn't keep awake?" "No, uncle. I suppose I must have been very tired to-night." "The Vicar's plums last night; my pears to-night. Humph! It's time that young fruit pirate was caught." Tom thought the matter over for days as he worked at the speculum now approaching completion.
The happy thought occurred to me of substituting an open metal mould for the closed sand one. I soon had the metal mould ready for casting. It consisted of a base plate of cast iron, on the surface of which I placed a ring or hoop of iron turned to fully the diameter of the intended speculum, so as to anticipate the contraction of the alloy.
If I were asked what course of practice was the best to instil a true taste for refined mechanical work, I should say, set to and make for yourself from first to last a reflecting telescope with a metallic speculum. Buy nothing but the raw material, and work your way to the possession of a telescope by means of your own individual labour and skill.
