VARIOLA VACCINAE. 203 



GlinsLurgh inoculated eleven cows with small-pox matter, the 

 result of which was the production upon one of them of vesicles 

 having all the character of vaccine vesicles, and from which a 

 stock of genuine lymph w^as obtained. In 1830 Dr. Sonderland 

 of Barmen infected cows with the disease by enveloping them in 

 blankets taken from the bed of a patient who had died of small- 

 pox. Various other experiments have been made to this end 

 by Mr. Ceely of Aylesbury, Mr. Badcock of Brighton, and by Mr. 

 ]\Iacpherson in India. Mr. Ceely, in the tenth volume of the 

 Transactions of the Provincial Medical and Surgical Association 

 gives a most interesting history of the communication of the 

 disease to cattle from man without inoculation. " At the village 

 of Oakley, about sixteen miles from the town of Aylesbury, 

 small-pox had been epidemic from June to October 1840. Two 

 cottages, in which three persons resided during tlieir illness, were 

 situated on each side of a long narrow meadow, comprising 

 scarcely two acres of pasture land. One of these three patients, 

 though thickly covered with pustules of small-pox, was not 

 confined to her bed after the full development of the eruption, 

 but frequently crossed the meadow to visit the other patients, 

 a woman and a child, the former of wdiom was in great danger 

 from the confluent mahgnant form of the disease, and died. 

 According to custom she was buried the same evening ; but the 

 intercourse between the cottages across the meadow was still 

 continued. On the day following the death, the wearing apparel 

 of the deceased, the bed-clothes and bedding of both patients, 

 were exposed for purification on the hedges bounding the 

 meadow, the chaff of the child's bed was thrown into the 

 ditch, and the flock of the deceased woman's bed was strewed 

 about the grass over the meadow, where it was exposed and 

 turned every night and for several hours during the day. This 

 purification of the clothes continued for eleven days. At that 

 time eight milch cows and two young heifers were turned into 

 the meadow to graze. They entered it every morning for this 

 purpose, and were driven from it every afternoon. Wlienever 

 the cows quitted the meadow the infected articles were again 

 exposed on the hedges, and the flock of the bed was spread out 

 on the grass and repeatedly turned. These things remained till 

 the morning, when the cows were readmitted, and the con- 

 taminated articles were supposed to be withdrawn, It a^Dpears,
