... irregular, more or less flattened and twisted tube (see Fig. 1). We know it is a tube, because on taking a thin, narrow slice across a fibre and examining the slice under the microscope, we can see the hole or perforation up the centre, forming the axis of the tube (see Fig. 2). Mr. H. de Mosenthal, in an extremely interesting and valuable paper (see J.S.C.I.,[1] 1904, vol. xxiii. p. 292), has recently shown that the cuticle of the cotton fibre ...

This Liquor I have upon tryal found the most tender of any spirituous Liquor, and those are much more sensibly affected with the variations of heat and cold then other more flegmatick and ponderous Liquors, and as capable of receiving a deep tincture, and keeping it, as any Liquor ...

... can be placed in such position that the larynx is reflected in the mirror and thus can be observed by the operator. Those who have had their throats examined with the laryngoscope will recall that the operator wears a reflector over his right eye. Through a central perforation in the reflector he views the image, which is seen the more clearly for the light thrown upon the laryngoscopal mirror by the reflector. It would be possible after comparatively little practice with the apparatus for a singer to examine his own larynx. But it would be most inadvisable for him ...

The motive for perforating the arms of the young men is to make them skilful hunters; at each perforation the sufferer is cheered by the promise of another sort of game or fish which the surgical operation will infallibly procure for him. The same operation is performed on the arms and legs of the girls, in order that they may be brave and strong; even the dogs are ...

But we have already shew'd how the birch is to be treated: Fasten therefore a bottle, or some such convenient vessel appendant; this does the effect as well as perforation or tapping: Out of this aperture will extil a limpid and clear water, retaining an obscure smack both of the tast and odor of the tree; and which (as I am credibly inform'd) will in the space of twelve or fourteen days, preponderate, and out-weigh the whole tree it ...

... Moreover, when the wind admits, there will be freely-moving steerable balloons wagging little flags to their friends below. And so far as the resources of the men on the ground go, the balloons will be almost invulnerable. The mere perforation of balloons with shot does them little harm, and the possibility of hitting a balloon that is drifting about at a practically unascertainable distance and height so precisely as to blow it to pieces with a timed shell, and to do this in the little time before it is able to give ...

Without due vigilance how readily might these interesting ...

... stamp office he was told by the chief that the government was losing 100,000 pounds a year through the custom of removing stamps from old parchments and using them again. The chief also appreciated the new danger of easy counterfeiting. So he offered Bessemer a definite sum for his process of perforation, or an office for life at eight hundred pounds a year. Bessemer chose the office, and hastened to tell the good news to a young woman with whom he had agreed to share his fortune. In explaining his invention, he told how it would ...

The perforation of the cartilage that divides the nostrils, and the strange disfiguring ornament of a long bone or stick thrust through it, was now observed, as described by Captain Cook; and the same appellation of sprit-sail yard, was ludicrously applied ...

Prepared powder was sifted through the lines of perforation and fixed by the application of heat, and we then had the entire composition exactly outlined upon the ground. After that the work of superimposing color and shading by needle weaving was a labor of love and diligent fingers during many months. Every inch of stitchery was carefully ...

They are all circumcised, and have also a strange custom, hardly practised any where else but in Pegu, having a nail of tin in a perforation through the glans, which nail is split at one end and rivetted; but which can be taken out as they have occasion, and put in again. This is said to have been contrived, on the humble petition of the women, to prevent perpetrating an unnatural ...

... In this genus the wall is quite thin, and at maturity opens differently in different species. In several species it opens irregularly, the entire wall becoming very brittle and cracking up into bits, as in the giant puff-ball. In the remaining species it opens by a distinct perforation at the apex, and the remainder of the wall is more or less pliant and membranous. All of the puff-balls are said to be edible, at least are harmless, if eaten when the flesh is white. They should not be eaten when the flesh is dark, or is ...
