Some tubing has occasional knots or lumps of unfused material. The rest of the tube is usually all right, but often the defective part must be cut out. The presence of striations running along the tube is generally an indication of hard, inferior glass. Crookedness and non-uniformity of diameter are troublesome only when long pieces must be used.
It dwelt there; contemplated us from its myriads of deep-set, sparkling striations. In its wake swam, one by one, six others their tops raising from the vapors like the first, watchfully; like shimmering backs of sea monsters; like turrets of fantastic angled submarines from phosphorescent seas.
The following qualities are desirable in a glass for ordinary working: moderately low working temperature, freedom from air bubbles, striations and irregularities, proper composition, so that the glass will not devitrify or crystallize while being handled at its working temperature, ability to withstand rapid heating without cracking.
The Red Sea lay there beyond the uplifted line of desert sand, and it was the birthplace of many mists and unpropitious signs. Would the sun look upon the king through a veil, or openly? Would he smile upon the purposes of the Pharaoh? There were striations, watery and colorless, in the lower slopes of the morning sky, and these were taking on the light of dawn without its hues.
There are in it certain striations which divide it more or less irregularly into segments, each of these corresponding to a certain department of the physical brain, so that every type of thought should function through its duly assigned portion.
There, above the spot where he had guessed the Israelites to be, a straight and mighty column of vapor extended up, up into the smoky blue of the sky. The tortuous shapes of the striations across the zenith indicated that there was great wind at that height, but the column did not move or change its form.
Enoch worked out of this depression and found a foothold on the bottom-most of the deep weathered, narrow strata that here formed a fifty-foot terrace. These terraced strata gave back for half a mile in uneven and brittle striations that were not unlike rude steps. Above them rose a sheer orange wall, straight to the sky.
Deep traces have therefore been left upon the text of the Bible by these several stages of expansions, additions, modifications, revisions, and incorporations they appear to the scholar of biblical literature much like the striations grooved in the rocks by large glaciers to the student of Geology."
Horns with fine transverse wrinkles; yellowish striations, or bold knobs or brown; sub-triangular in front; blackish; in male in male, spreading outward more compressed or angular, and forward with a sweeping backward circular sweep, points with a scythe-like curve or turned outward and forward spirally, points turned upward and backward.
The magnifying-glass looks in vain for the fine striations usually found in the musical instruments of the insect world. All is smooth on either hand. How then is the sound engendered? Rub the end of the moistened finger on a strip of glass, or a window-pane, and you will obtain a very audible sound, somewhat analogous to that emitted by the chafer.
