I returned to the laboratory to find that Craig had taken out of a cabinet a peculiar looking arrangement. It consisted of thirty-two tubes, each about sixteen inches long, with S-turns, like a minute radiator. It was altogether not over a cubic foot in size, and enclosed in a glass cylinder.
The same halfway doubling is recorded to occur among composites sometimes, and from the same source I possess in my collection a head of Pyrethrum roseum, bearing on half of its disk elongated corolla tubes, and on the other half the small disk-florets of the typical species. It is a current belief, that varieties are improved by continued culture.
A ring at the doorbell caused us to think that he had been found, but it proved to be the student to whom Kennedy had telephoned at his own laboratory. He was carrying a heavy suitcase and a small tank. Kennedy opened the suitcase hastily and disclosed a little motor, some long tubes of rubber fitting into a small rubber cap, forceps, and other paraphernalia.
To make blood transparent or laky. Place in each of three test tubes two or three teaspoonfuls of defibrinated blood, obtained from Experiment 89, labeled A, B, and C. A is for comparison. To B add five volumes of water, and warm slightly, noting the change of color by reflected and transmitted light.
No better illustration of this characteristic can be found than in the development of the nickel pocket for the storage battery, an element the size of a short lead-pencil, on which upward of five years were spent in experiments, costing over a million dollars, day after day, always apparently with the same tubes but with small variations carefully tabulated in the note-books.
The priest was a lively old man, but rather a bore from being able to talk of scarcely anything except homoeopathy, having been smitten with the mania during a recent visit to Santarem. He had a Portuguese Homoeopathic Dictionary, and a little leather case containing glass tubes filled with globules, with which he was doctoring the whole village.
In the Ctenophorae, another complication of structure is introduced in the combination of vertical with horizontal tubes and the external appendages accompanying them. But, whatever their differences may be, a very slight effort of the imagination only is needed to transform any one of these forms into any other.
'In the construction of these enormous balloons, M. Pétin proposes to substitute, in place of the silken bag hitherto used to contain the gas, a rigid envelope of a cylindro-conical form, composed of a series of metallic tubes, laid one above the other, and supplied with gas obtainable to any amount and almost instantaneously from the decomposition of water by a powerful electric battery; and with these resources at command, M. Pétin conceives that balloons might be constructed on a scale even larger than that just given!
The grate area is 17.5 square feet, and the heating surface is, in the tubes, 1,096; fire-box, 110; total, 1,206. There are double frames to give outside bearings to the leading axle, as in the Great Western engine, and the engine is fitted with a steam brake.
In the lungs it can be seen from their cellular substance, which consists of bronchial tubes continued down to the minutest air-cells, which are receptacles of air in respirations; these are what the thoughts make one with by correspondence.
