Side 73 - Tis thus Omnipotence his law fulfils, And vengeance executes what justice wills. Again— the band of commerce was designed To associate all the branches of mankind ; And if a boundless plenty be the robe, Trade is the golden girdle of the globe.
Side 36 - Tis hard to say if greater want of skill Appear in writing or in judging ill ; But of the two less dangerous is th' offence To tire our patience than mislead our sense : Some few in that, but numbers err in this; Ten censure wrong for one who writes amiss ; A fool might once himself alone expose ; Now one in verse makes many more in prose.
Side 379 - The straight line drawn at right angles to the diameter of a circle, from the extremity of it, falls without the circle...
Side 198 - Never, perhaps, was witnessed a finer scene than on the deck of my little ship, when all hope of life had left us.

Side 379 - Again, between the straight line AE and the circumference, no straight line can be drawn from the point A, which does not cut the circle. Let AG...
Side 363 - What is a man, If his chief good and market of his time Be but to sleep and feed ? a beast, no more. Sure, he that made us with such large discourse, Looking before and after, gave us not That capability and god-like reason To fust in us unused.
Side 132 - Silhet, the nuts of the semecarpos anacardium, and the berries of the holigarna longifolia, having been steeped for a month in clear water, are cut transversely, and pressed in a mill. The expressed juice of each is kept for several months, taking off the scum from time to time. Afterwards the liquor is decanted, and two parts of the one are added to one of the other, to be used as varnish.
Side 385 - These clutches are simultaneously acted upon by the rods and small lever b, with the helical springs mm, and which, according as they are forced to the right or left, will enable the carriage to be moved forward or backward.
