Transcriber's note:

Minor punctuation errors e.g. missing "." in "Fig." have been corrected.

Inconsistent hyphenation and use of ligatures has been left e.g. cast-iron and cast iron. (Often the difference is between the hyphenation in the text, that used in captions to illustrations and that used in the index.)

Both gasolene and gasoline are used in the text

Both carburator and carburetor are used in the text

Many of the table values have errors which can be shown by graphing the results, these have been left as printed but are noted here:

p.5. Absolute Pressure 5, Latent heat of 958.30 should be 956.30

p.199.
Air temperature 33 degF. Weight of cu. ft. air 566.4 should be 560.4
Air temperature 43 degF. Weight of cu. ft. air 548.4 should be 542.4
Air temperature 49 degF. Weight of cu. ft. air 542.5 should be 541.5
Air temperature 58 degF. Weight of cu. ft. air 534.9 should be 530.9
Air temperature 63 degF. Weight of vapor/cu. ft. air should be 6.45

p.203. Air Temp. 106,
2 deg. depression of wet-bulb thermometer 95 should be 93

p.211. Dew point. 69,
12 deg. depression of wet-bulb thermometer 84 should be 48

p.214.
Dry-bulb temp. 39,
12 deg. depression of wet-bulb thermometer 23 should be -23
Dry-bulb temp. 38
9 deg. depression of wet-bulb thermometer -6 should be 6

p.314. Column heading should read Watts per lamp 25 40 60 100 150 250
