� Early in the following year, 1812, they went out to India together; and his delight was great in returning to the country where he had toiled so long, and had made many friends. This time, however, his stay in the east was to be brief. She has done it [he says] by attaching to them as slaveholders, in the eyes of the world, the guilt of the abuses of an institution of which they are absolutely guiltless. Her story is so devised as to present slavery in three dark aspects: first, the cruel treatment of the slaves; second, the separation of families; and, third, their want of religious instruction. 6 And the Word of God came to Adam and raised him from his death, and opened Eve's mouth that she might speak.

The charge of carburetted air is drawn through a non-return valve into the crank chamber during the upstroke of the piston, and452 compressed to about 4 lbs. pressure per square inch on the down stroke. When the piston approaches the bottom end of its stroke the upper edge first overruns an exhaust port, and almost immediately after uncovers an inlet port on the opposite side of the cylinder and in communication with the crank chamber; the entering charge, being under pressure, assists in expelling the exhaust gases from the cylinder. On the next upstroke the charge is compressed into the combustion space of the cylinder, a further charge simultaneously entering the crank case to be compressed after the ignition for the working stroke. To prevent the incoming charge escaping through the exhaust ports of the cylinder a deflector is formed on the top of the piston, causing the fresh gas to travel in an upward direction, thus avoiding as far as possible escape of the mixture to the atmosphere. From experiments conducted in 1910 by Professor Watson and Mr Fleming it was found that the proportion of fresh gases which escaped unburnt through the exhaust ports diminished with increase of speed; at 600 revolutions per minute about 36 per cent of the fresh charge was lost; at 1,200 revolutions per minute this was reduced to 20 per cent, and at 1,500 revolutions it was still farther reduced to 6 per cent. �
