Cow-Pock Institution. 101 



From my situation, as surgeon to the Foundling Hospi- 

 tal, I have had it fully in my power to select such cases as 

 had been faithfully recorded by me to have undergone vac- 

 cination at the earliest period of cow-pock inoculation in 

 this city, and such have been approved of by those gentle- 

 men who have honoured me with their presence, to wit- 

 ness and subscribe their names to the progress and event 

 of the following experiment on nineteen children chosen 

 for the purpose, who were divided into two (.lasses. The 

 first nine comprehend those who in a state of infancy were 

 vaccinate d I v me between the 30th of December 1800 

 and 3d of July 1801, now more than eight years. These 

 were again inocuUucd with sn»all-pox infection by George 

 Stewart, esq. surgeon-general, on the 24th of July, 1804, 

 (and witnessed by several gentlemen of the first respecta- 

 bility in their profession,) m like manner to disprove the 

 assertions of Mr. Goldson, as may be seen in the twelfth 

 volume of the Medical ami Physical Journal, and with the 

 most complete success — all having resisted the small-pox, 

 although exposed to it in every way possible. These nine 

 children, with ten others, who were also vaccinated by me 

 in a state of infancy, from 15th of July 1801 to 30th of 

 August 1802, upwards of seven years, were again submitted 

 to small-pox inoculation, on Friday, 22d of December last; 

 the infection taken from a child of Mr. Stafford's, No. 7, 

 Hanbury-lane, in confluent small-pox, and the matter in- 

 serted in two places in the arm of each child, in a fluid 

 state,- and in the greatest quantity. In every instance, the 

 punctures in the arm of each child from the third day in- 

 flamed, and continued until the seventh, when the inflam- 

 mation gradually subsided, as certified by Mr. Stewart, and 

 marked in a table, which, in another publication, will be 

 more fully expressed ; — which circumstance has proved the 

 activity of the small-pox matter inserted, and which must 

 have affected the constitution, were it in the least suscepti- 

 ble of the disease. Fourteen days have now elapsed, the 

 inflammation of the punctures is entirely gone, and never 

 was attended with the slightest fever, sickness, or eruption. 



J n corroboration of the above facts, conducted with 

 everv decree of accuracy, and which cannot admit of the 

 smallest doubt on the minds of those gentlemen who have 

 witnessed them, and hereunto subscribed their names; I 

 can safelv assert, that T have submitted upwards of five 

 hundred infants and children, vaccinated by me at this In- 

 stitution, and at the Dispensary for Infant Poor and Cow-
