THE LUNG PLAGUE. 51 



On the 18th October tliroo members of the commission proceeded to a fresh inoculation. They operated npou the 

 Nos. 1, 3, 4, 5, 7, and 8, from Tirlemont, and upon tho Ardennes cow No. 4. 



The No. 7 of the latter brood and the No. G of the former were reserved. 



Two of tho Ardennes cows, Nos. 5 and 6, which were successfully inoculated, having been isolated in a stable, cohab 

 ited from the 24th of September with pneumonic beasts. When it was certain that the operation had had a negative 

 result upon the Ardennes cow No. 7, and after the cicatrization of tho puncture, tho sumo locality was assigned to it, 

 on the 1st of October, for abode. 



The ox No. 2, from Tirlemont, entered there on the 23d of October, and the heifer No. fi on tho 25th of tho same month, 



A third inoculation, performed on the 18th of November upon tho beasts from Tirlemont, Nos. 1, 3, 4, 5, 7, and 8. 

 was not more efficacious than the preceding. 



From the 24th of September, the date of tho experiment, there has only occurred a first space of one day, and a second 

 of eight, during which the stable has not contained pneumonic beasts ; the number of the cattle has varied from one to 

 three. Up to this day the three inoculated beasts, and this two upon which the inoculation was unsuccessful, have 

 experienced 110 attack from the cohabitation with infected animals. 



Two aged cows, inoculated by M. Willems, at Hasselt, entered the same locality on the 15th of November. 



On the 28th ot September, two of the Ardennes boasts, Nos. 3 and 8, were dispatched to Tirlemont to bo placed in 

 infected stables there, by the care and under the superintendence of M. \Vindelincx. 



A third experiment, intrusted to M. Dele, has been organized at Deurno, in the province of Antwerp. The superior 

 of tho Abbey of La Trappo has been pleased to place at tho disposal of the commission, for this purpose, two heifers 

 belonging to the community, and which were inoculated with the least equivocal success on the 27th of May, 1852. 



On the 30th of October, the Ardennes beasts Nos. 1, 2, and 4 were conducted to Huy, where a fourth experiment is 

 being carried out under the superintendence of JIM. Marcops and Giic rin. 



Not one of tho animals inoculated, successfully or unsuccessfully, has contracted exudative pleuropncumonia. 



While these experiments were going on, -fifty-four veterinary surgeons, including Dr. 

 Willems, inoculated five thousand three hundred and one head of cattle. They con 

 sisted in

Eighty-six, including eleven beasts inoculated in the dewlap, died from the effects 

 of the inoculation. 



Seventy-four lost the tail up to the root. 



Three hundred and four lost it in part. 



Seventy-three contracted exudative pleuropneumonia after having been success 



inoculated. 



After careful examination, it resulted that fifty-five cases of exudative pleuropneumo 

 nia, well attested, occurred upon beasts inoculated with unequivocal success. The space of 

 time which elapsed with these animals between the inoculation and the ^ first appearance 

 of the pneumonia symptoms varies from seventeen to one hundred and thirty-six days.
