Obtain a general notion as to capacity/ or size of the thorax, rela-tive to the height, weight, and age of the individual, allowing for fatnessor emaciation (Spirometry; see under ^•Tuberculosis^). [By spirometry we measure the amount of air received into the instrument of Mr. Hutchinson, mentioned at p. 274, is unwieldy, [Fig. n*. * Fig. 11. The nuts A and B are to be unscrewed and boiled water is to be pouredin at the orifice A, until it begins to trickle from the opening B ; leave it for half aminute and then replace both the nuts with their leather washers. The instrumentis now ready for use, and it will not need refilling for two or three months unlessconstantly used. The openings C and D are for the entrance and exit of the expiredair. The free end of the tube is to be Stretched over C, and the nut D should be re-moved.] PHYSICAL EXAMINATION OF THE CHEST. 553 inexact, difficult to use, and is open to other objections. Moreavailable instruments, to determine the vital capacity of the luno-s,have been recently invented. Mr. Coxeters spirometer is is a bag of India-rubber cloth large enough to hold the air whichmay be expired by a person of large pulmonary capacity, fittedwith a glass mouth-piece.
