HAND-BOOK OF LAND AND MARINE ENGINES.

assistant: The passage seems part of a handbook for land and marine engines.
It is a table of multipliers used to find the mean pressure at multiple points of cut-off, listing several expansion ratios from 1.0 to 5.7 with their corresponding multipliers. To obtain the mean's value, first identify the correct expansion ratio, then take the multiplier opposite to it, and multiply it by the full pressure of the steam per square inch as it enters the cylinder.

assistant: Following is the corrected text. Some numbers have been updated, and the table should be checked with particular attention to similar characters being changed,  for example, a 3 substituted by an 8.

Take the number corresponding to this and take the multiplier opposite to it, and multiply the 
full pressure of the steam per square inch as it enters the cylinder by it.
