The crystals are then dissolved in alcohol, which, on being poured into water, parts with them in the same form. Hyoscyamine crystallizes in the acicular form, with greater difficulty even than atropine, it also forms less compact crystals. Its fusing point is 149.6 deg. F. I have not yet succeeded in crystallizing any of its more simple salts. The double platinum salt melts at 392 deg.
Signs of volcanic activity are present more or less throughout its whole depth and for some distance along its margin, in the form of steam-cracks, jets of sulphurous vapor, blowing cones, accumulating deposits of acicular crystals of sulphur, etc., and the pit itself is constantly rent and shaken by earthquakes.
Soon Birdie and myself were a mass of acicular crystals; it was a true easterly fog. I galloped on, hoping to get through it, unable to see a yard before me; but it thickened, and I was obliged to subside into a jog-trot.
Professors Babcock and Munroe, of Chicago, call the plants either the Hydrogastrum of Rabenhorst, or the Botrydium of the Micrographic Dictionary, the crystalline acicular bodies being deemed parasitic. Dr. B. deserves great credit for his honest and careful work and for his valuable paper. Such efforts are ever worthy of respect.
The obelisk is from another of Nature's patterns; it is only a gigantic acicular crystal. The Egyptians knew what a monument should be, simple, noble, durable. It seems to me that we Americans might take a lesson from those early architects. Our cemeteries are crowded with monuments which are very far from simple, anything but noble, and stand a small chance of being permanent.
Signs of volcanic activity are present more or less throughout its whole depth, and for some distance round its margin, in the form of steam cracks, jets of sulphurous vapour, blowing cones, accumulating deposits of acicular crystals of sulphur, etc., and the pit itself is constantly rent and shaken by earthquakes.
One, named Einerguendi by Brown, consisted of compact felspar, coloured green by chlorite, with grains of quartz and acicular crystals of felspar.
A dig with the Guanche magada or lanza, the island alpen-stock, either outside or inside the crater, will turn up, under the moist white clay, lovely trimetric crystals of sulphur, with the palest straw tint, deepening to orange, and beautifully disposed in acicular shapes. The acid eats paper, and the colours fade before they leave the cone.
Several extensive streams, however, belonging to this series, retain their stony character; these are either of a blackish-green colour, with minute acicular crystals of feldspar, or of a very pale tint, and almost composed of minute, often scaly, crystals of feldspar, abounding with microscopical black specks; they are generally compact and laminated; others, however, of similar composition, are cellular and somewhat decomposed.
Simphorien de Marmagne, in the department of La Cote d'Or. Acicular arsenical lead ore, at St. Prix, in the department of Saone and Loire. This substance was found among some piles of rubbish, near old works made for exploring a vein of lead ore, which lies at the foot of a mountain to the north-east, and at three quarters of a league from the commune of St. Prix.
