Superficial touch is tested by means of a wisp of cotton wool stroked gently across the skin; the capacity of discriminating two points as separate, by a pair of blunt-pointed compasses; the sensation of pressure, by means of a pencil or other blunt object; of pain, by pricking or scratching with a needle; and of sensibility to heat and cold, by test-tubes containing water at different temperatures.
As Jan reached the open deck he had drawn in first one and then another and another long, tremulous, deep breaths which, passing through the infinitely delicate test-tubes of his wonderful nostrils, recorded in his brain impressions more vivid and accurate than any that vision could supply to him.
If Kennedy himself had thrown a bomb or scattered broadcast the contents of the test-tubes, the effect could not have been more startling than his last quiet sentence and sentence it was in two senses. "Signed," he said, folding the paper up deliberately, "Ekaterina Nevsky." It was as if a cable had snapped and a weight had fallen. Revalenko sprang up and grasped Kazanovitch by the hand.
"The manipulation of the tins is quite easy." He conducted us to a small room on the top floor, which I at once saw was fitted as a laboratory, and which contained microscopes, incubators, stands of test-tubes, and all the other apparatus appertaining to the bacteriologist. One of his assistants had carried up four small tins of beef, with a couple of bottles of beef extract.
Craig took the beakers and test-tubes from the shelf behind the curtain and placed them on the little deal table that had been so merrily dancing about the room. "The increasing frequency with which tales of murder by poison appear in the newspapers," he began formally, "is proof of how rapidly this new civilisation of ours is taking on the aspects of the older civilisations across the seas.
The end in which I lay, was, as I have said, typical of an Eastern house, and a large, ornate lantern hung from the ceiling almost directly above me. The further end of the room was occupied by tall cases, some of them containing books, but the majority filled with scientific paraphernalia; rows of flasks and jars, frames of test-tubes, retorts, scales, and other objects of the laboratory.
Kharkoff is going to prepare some cultures in the test-tubes to-night so that I can make a microscopic examination of the blood of Saratovsky, Samarova, and later of his servant. The tubes will be ready early in the morning, and I have arranged with the doctor for you to call and get them if you have no objection." I assented, and we started downstairs.
Then she continues her ideal shoving of it through all the stages of an ideal up-bringing, she loves it as a chemist loves his test-tubes in which he analyzes his salts. The poor little object is his mother's ideal. But of her head she dictates his providential days, and by the force of her deliberate mentally-directed love-will she pushes him up into boyhood.
I think I shall have something interesting to say to-night as a result of our visits, at least." During the remainder of the day Kennedy was closely confined in his laboratory with his microscopes, slides, chemicals, test-tubes, and other apparatus. As for myself, I put in the time speculating which of the fakirs had been in some mysterious way connected with the case and in what manner.
As he dragged himself to his feet by means of the bar-rail, he saw a man in a squirrel-skin parka lift a beer-mug to hurl at Trethaway, a couple of paces off. And the fingers, which were more used to test-tubes and water colors, doubled into a hard fist which smote the mug-thrower cleanly on the point of the jaw. The man merely dropped the glass and himself on the floor.
