She sprang toward the closet door, which stood ajar, and in an instant Balcom was with her. The two were concealed in the closet as the laboratory door opened and Locke entered. Locke walked to his table of test-tubes and picked up one containing mercury. What prompted this action he did not know. Perhaps it was his fascination for the elusive metal. Perhaps it was some subconscious feeling.
Before coming to a conclusion, let us try an experiment. I deprive certain occupied peas of their skin, and I dry them with abnormal rapidity, placing them in glass test-tubes. The grubs prosper as well as in the intact peas. At the proper time the preparations for emergence are made.
What would Joseph Priestley, the discoverer of oxygen, and Cavendish, the discoverer of nitrogen, think could they step into the laboratory of Professor Ramsay and see test-tubes containing argon and helium and krypton and neon and zenon?
"Very well," he said, making no move to follow me. I shook my head doubtfully. It was impossible to force a card on Kennedy. Instead of showing any disposition to switch off the laboratory lights, he appeared to be regarding a row of half- filled test-tubes with the abstraction of a man who has been interrupted in the midst of an absorbing occupation. "Good night," I said at length.
He could see steam arising from the sterilizer: he knew surgical instruments were boiling merrily away there. A table was littered with objects suggesting careful examination: a fine microscope in position; a centrifuge, Bunsen burners, test-tubes; elsewhere other apparatus of a description to make the uninitiated actively sympathetic with the presumable coming victim.
The column is erected at a spot frequented by Flies, in a dim light. Its mouth, closed with a wire-gauze cover, reaches the level of various other appliances, test-tubes and jars, which are already stocked or awaiting their colony of vermin. When the position is well-known to the Flies, I remove the other tubes and leave the column, lest the visitors should turn aside to easier ground.

I cannot look forward to such a complete revolution with any degree of pleasure, so I guess I will have to keep along in the old store, much as I would like to devote the rest of my life to test-tubes, crucibles, and scales." There are many such men. Change is more hateful to them than unloved work. They fall into grooves and ruts.
The deep workings would be full, the main galleries would be full, but in the high workings reached by inclines from the main roads, there would be a certain amount of air cut off, so to speak, by the water and squeezed up by it. The little science-primers explain how water behaves when you pour it down test-tubes. The flooding of Twenty-Two was an illustration on a large scale.
=Flanging a Tube.= This operation produces the characteristic flange seen on test-tubes, necks of flasks, etc., the object being twofold: to finish the end neatly and to strengthen it so that a cork may be inserted without breaking it. This flanging may be done in several ways.
