The figure of this diagram shows that the slide is passing steam, this is shown by the line at d, which should have been shown a curved line as at a, the eduction parts too contracted, the card should have had the figure as at b, the slide has not lead enough, the card should have shown as dotted at c. The diameter of the cylinder is 3-feet 6-inches, stroke 5-feet, and making 20f revolutions per minute. 3-faet 6-inches equal to 42-inches. 42 x 42 x-7854 x 158 x 5 x 2 x 83=133-28 H. P. Steam is admitted into the cylinder at 25 lbs. pressure per square inch, above the pressure of the atmosphere, and it is cut off at of the stroke, required the mean pressure on the piston throughout the stroke, supposing the vacuum to be perfect. The following method from Thomas Simpson, F.E.S., for finding the area of irregular curved surfaces. To the sum of the extreme pressure per square inch, add four times the sum of the even pressures, and twice the sum of the odd pressures; this product divided by 3 will give the work done expansively on 1-inch of the piston. The even numbers are 2 and 4; the odd numbers are 3 and 5; the last division the mean is taken, that is 6-6 + 8=7-3. Therefore the even numbers 20+10=30 x 4=120. odd 133 + 8=21-3 x 2=42-6. And the mean of... 8 +...
