1 4 8 Second Letter to Mr. Tllloch on the Cow- Pock. 



had paid particular attention to this subject, which afforded 

 some observations applicable to the present inquiry, and de- 

 cisive upon a large scale oi calculation, which a table by 

 figures more clearly evinced. The experience of forty-two 

 years preceding the introduction of inoculation into this 

 countrv, was alreadv placed in a clear point of view in the 

 Philosophical Transactions, by Dr. James Jurin, who was a 

 sanguine advocate for inoculation, and whose testimony was 

 therefore unexceptionable. His numbers were taken from 

 the yearly l)ills of mortality, and the reason why the four- 

 teen years from 1CS6 to 1701 were omitted, was, because in 

 the bills of those years the account of the small-pox and 

 measles were not distinguished, as in the preceding and fol- 

 lowing vears, but were joined together in one article, so that 

 from them no certain account could be drawn of the num- 

 ber of persons that died of the small-pox. It appeared by 

 these tables, that out of 1,00.5,279 burials within the last 

 forty-two years, 1742 persons more have died of the small- 

 pox than the proportionate number, as collected from the 

 experience of the first forty-two years : seventeen more 

 burials therefore in one thousand had been occasioned by the 

 small-pox, since inocnhilion had heen adopted. 



"Taking London and the out parishesas containing nearly 

 1,000,000 of people, he calculates, that 3000 probably died 

 yearly by the small-pox, or eight every day; or allowing 

 Great Britain and Ireland to contain 12,000,000 of people, 

 no less than 36,000 annually. About eight persoris die by 

 the small-pox ererij daij in the metropolis and its environs, 

 or shout fjhf -six in eachweek." 



The inoculation of the small -pox, therefore, increases 

 instead of diminishing the number of burials. 



This circumstance soon struck the discerning mind of 

 Baron Dinisdale, who had the honour of being selected from 

 among the faculty here, and went from England in order to 

 inoculate the empress of all the Russias; which succeeding, 

 besides a pension, he was made a counsellor of state, and 

 physician to her imperial majesty. 



Although every inducement led him to conceal the fact, 

 yet, actuated by the love of truth, and patriotism towards a 

 country to which he owed his promotion in life, he came 

 forward to sound the alarm, arid show how a seeming bles- 

 sing was an actual evil to the state. < 



" Althousrh the loss," says he, " under inoculation is 

 very inconsiderable, almost the whole of those that are ino- 

 culated recovering, yet by spreading the disease, a greater 

 proportion take it in the natural way: more lives svt now
