    The average circumference of the chest above the nipples is 38 inches, but considerable variations are possible without by themselves indicating disease. The signs of quiescent tubercular deposit elicited by percussion are a want of resiliency in the chest walls in the infra-clavicular regions, a greater or less ab- sence of the normal resonance, at the same spot, or in the supra-scapular spaces, which is specially sig- were under observation, or by dividing tbe total number of deaths in each class by tbe same number, and thus obtaining tbe number of deaths in each year. I have preferred the former plan, as I object to talking of the death of a fractional part of a man. We talk of this constantly in the ratio of deaths per 1000 of strength, but this is merely a proportional statement, whereas the other is supposed to be an actual state- ment of the deaths. In case this is not quite clear, I would put it thus :—The number of men over whom my observa- tions extended was in 1st class . . 416 ] 2d „ , . 342V1126 3d „ . . 368 ] but the deaths in these classes occurred in different periods of time— In the 416 in 3-632 years. „ 342 in 3-348 „ „ 368 in 3-277 „ The first would be equal to 1511 men under observation for one year, the second to 1145, and the third to 1206 for the same period. Or it may be stated thus :—The deaths in each complete year under observation were in the 1st class , . 8-5352 2d „ . . 6-8699 3d „ . . 7-3238 I think the multiplication of the strength, or numbers imder observation, looks better than the division of the deaths by the period of observation.
