They would obtain a product of the highest quality, for the carnivorous worm also owns its pepsin, pepsin of a singularly active kind, as the following experiments will show us. I divide the white of a hard-boiled egg into tiny cubes and place them in a little test-tube.
We boiled the liquids in the flask and test-tube for a sufficient time to expel all the air contained in them. We then withdrew the heat from under the test- tube, and immediately afterwards covered the water which it contained with a layer of oil and then permitted the whole apparatus to cool down.
Whether it was a question of history or of cosmogony, or whether he was handling a test-tube or a blow-pipe; what he was about I did not feel sure; but I took it for granted that it was some crucial question or other he was at work on, some point bearing on the thought of the time. For the Master, I have observed, is pretty sagacious in striking for the points where his work will be like to tell.
The arena of a large bottle enables each athlete to keep out of the other's way, respected by her adversary, who is respected in her turn. Let us reduce the lists, diminish the enclosure. I put Bumble-bee and Tarantula into a test-tube that has only room for one at the bottom. A lively brawl ensues, without serious results.
I placed a morsel of flannel on which the mother moth had been lying all the morning at the bottom of a long test-tube or narrow-necked bottle, just permitting of the passage of a male moth. The visitors entered the vessels, struggled, and did not know how to extricate themselves. I had devised a trap by means of which I could exterminate the tribe.
The telegram which we eventually received came late one night just as I was thinking of turning in and Holmes was settling down to one of those all-night chemical researches which he frequently indulged in, when I would leave him stooping over a retort and a test-tube at night and find him in the same position when I came down to breakfast in the morning.
He was the bored aristocrat, mutely protesting against something that "wasn't done." He dipped his slender fingers into his pocket. Then, drawing out the test-tube, and holding it up, he spoke with a drawling calm for which even Jimmy could not help admiring him. "All right! If I'm done, I'm done!" The sensation caused by his action and his words was of the kind usually described as profound. Mrs.
The process in operation was a complete mystery to me; the means and the end were alike incomprehensible. Thus, in the heavy silence of that room, a silence only broken by the regular bubbling from the test-tube, I found my attention straying from the table to the other objects surrounding it; and at one of them my gaze stopped and remained chained with horror.
There is no duel to the death in the narrow arena of the test-tube, any more than in the wider lists afforded by the bottle. Utterly timid once she is away from home, the Spider obstinately refuses the battle; nor will the Bumble-bee, giddy though she be, think of striking the first blow. I abandon experiments in my study.
Such a death is poetic." He returned to the table and, observing meticulous care, emptied the few drops of colourless liquid from the condenser into a test-tube. Holding the tube near a lamp, he examined the contents, then poured the liquid into the curious yellow bottle. A faint vapour arose from it.
