[17] The figures for the Army are obtained from the Second Report, p. 278, down to 1888, the remaining six years being obtained from the _Final Report_, pp. 86, 87; but this small addition has involved a large amount of calculation, because the Commissioners have given the death-rates per 10,000 strength of four separate forces—Home, Colonial, Indian, and Egyptian, and have not given the figures for the whole Army, so as to complete the table in the Second Report. The figures for the Navy are obtained from the _Final Report_, p. 88. [18] Neither Sir C. Dilke nor the Post Office medical officers of the period referred to gave evidence before the Commission, and it shows to what lengths the Commissioners would go to support vaccination when such unverified verbal statements are accepted in their _Final Report_. [19] As regards the case of the nurses in small-pox hospitals, about which so much has been said, I brought before the Commission some evidence from a medical work, which sufficiently disposes of this part of the question. In Buck’s _Treatise on Hygiene and the Public Health_, Vol. II., we find an article by Drs. Hamilton and Emmett on “Small-pox and other Contagious Diseases,” and on page 321 thereof we read: “It is a fact fully appreciated by medical men, that persons constantly exposed to small-pox very rarely contract the disease. In the case of physicians, health-inspectors, nurses, sisters of charity, hospital orderlies, and some others, this is the rule; and of over 100 persons who have been to my knowledge constantly exposed, some of them seeing as many as 1,000 cases, I have never personally known of more than one who has contracted the disease; but there are many writers who believe perfect immunity to be extremely rare. In this connection attention may be called to the exemption of certain persons who occupy the same room, and perhaps bed, with the patients, and though sometimes never vaccinated, altogether escape infection.” And Mr. Wheeler shows that at Sheffield the hospital staff _did_ suffer from small-pox in a higher degree than other comparable populations (see 6th Report, Q. 19,907).
