On Vaccination. 



[Afrilj 



among these we must reckon the only three deaths which 

 followed vaccination, and which have already heen noticed. All 

 this is the resuk of the answer of 426 correspondents^ whose 

 testimony was sohcited by a circular letter.* 



In another place mention is made of the same erysipelatous 

 cases, probably comprehended under the 24 which have been 

 just raentiorted. The disease is ascribed to the too great depth 

 of the incisions, by n^eans of which the cow-pock matter had 

 heen pushed too far below the skin, instead of being introduced 

 between it and the epidermis. Other observations may give 

 some probability to this presiimptionj which we shall not attempt 

 to examme here.f 



At Aleppo the English Consul, Mr. Barker, has succeeded in 

 familiarizing tlie people to vaccination : 600 were vaccinated in 

 1806, without observing a single disagreeaV)le accident to follow. | 



in 1803 the Span-ish Government undertook the noble and 

 generous enterprise of sending out an expedition, which termi- 

 nated in 1806. Tlie sole object of this expedition was to convey 

 to all t' cir American and Asiatic possessions the new means of 

 presti \:Lig the colonies against the ravages of the small-pox. 



A certain number of children was embarked, who were to be 

 vaccinated successively daring the voyage. In this manner the 

 cow-pock virus was transported to the Canaries, to Porto Rico, 

 to the Caraccas, to Guatimala, to New Spain, to the Philippine 

 Islands, to Macao, to Canton, to the islands of Visaye, where 

 a hostile nation was so struck with this act of generosity on the 

 part of the Spaniards as immediately to lay down their armsc 

 The colonies of St. Helena, who had hitherto refused the cow- 

 pock matter from their own eountrymen, received it from the 

 Spaniards. The provinces of Terrafirma, of Carthagena, of 

 Peru, &c. likewise received the cow-pock matter, which was 

 even found indigenous near Puebla-de-los-Angeles, not far from 

 Valladolid, and in the Caraccas. The Viceroy of Nev/ Spain 

 lias attested that out of 50,000 individuals vaccinated in his 

 government not a single unfavourable accident had come to his 

 i^now ledge. § ,
