This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1895 edition. Excerpt: ...in diameter, their areas being respectively 50, 63, 78, 95, and 113 square inches.

In most instances only one heating and one ventilating register was used in any one room, but in a few cases they were doubled.

Fig. 1, respectively.
