Green hornblende is abundant at the rims of chlorite coronas in contact with amphibole-filled cracks, whereas it is minor (but not absent) in coronas in contact with chlorite-filled cracks.
“[…] the awfully hearty sort of Christmas cards that people do send to other people that they don't know at all well. You know. The kind that have mottoes[…]. And then, when you see [the senders], you probably find that they are the most melancholy old folk with malignant diseases. […]”
They'd serve cocaine, and you'd sit there, and base this cocaine. And you'd have an ounce gone in 24 hours.
Between the two pulleys c, c¹, and around the shaft a, is a muffle d, which receives at both ends the rounded heads of three, four, five, or more screws f, which act as levers. The levers are formed of a right and lefthanded screw, f, and f¹. The two screws are united together by means of a nut g, so that, by turning it, they are lengthened or shortened. The heads of the upper screws f¹, act upon the blocks e, e¹, contained in boxes supported by the plates h, h¹, through the centre of which passes the shaft a. These plates h, h¹, are fixed on the shaft a; they are of a smaller diameter than the inside of the pulleys c, c¹; their object is to keep the blocks e, e¹, from twisting.
By moving the muffle d, to the left, the levers or screws f, f, will force the blocks e, to bear against the inside of the pulley c, placed on that side. The motion of this pulley will cause the muffle d, and consequently the shaft a, to revolve. By pushing the muffle d, on the opposite side, the blocks e, will depress the pulley c, and the blocks e¹, will bear against the pulley c¹, the band of which being crossed, will cause the shaft a, to revolve in a reverse direction.
This shaft being furnished with a pinion, will transmit to a toothed wheel or rack, a motion in both directions at the desired instant, since it is only necessary to give the muffle d, a lateral movement from right to left, or from left to right, by means of a fork which acts on the part b.
By placing the muffle d, half way between the two pullies c, and c¹, the blocks e, and e¹, will release the said pullies, and the shaft a, will be motionless.
