174 ON INOCULATION AS A MEANS FOK THE 



" 7. Of 204 beasts inoculated by Dr Desaive, 13 died of 

 inoculation — viz., 6 per cent ; while in Belgium, of 189 inocula- 

 tions made by the central commission, only 3 died — viz., 1 or 

 1| per cent. Of 1400 beasts Dr Willems pretended to have 

 inoculated, 12 died, less than 1 per cent. Of 1200 inoculations 

 made by M. Manis, 22 deaths have followed, nearly 2 per cent. 

 In the majority of cases death ensued about the third or fourth 

 week, though in some instances not until two months after 

 inoculation. 



" 8. Of the 191 head of cattle inoculated and cured by Dr 

 Desaive, about 30 have lost the whole or part of their tails. 

 No calculation has yet been made as to the proportion that have 

 suffered in this way in Belgium ; nevertheless it has beeu 

 ascertained, in certain numbers of cases, that the loss of the 

 tail has been in the ratio of 3 out of 11 ; 10 out of 22 ; 12 out 

 of 50 ; 13 out of 51 ; and in one case, even all of 13 inoculated. 

 Complete recovery has been generally tardy and difficult with 

 many animals, occupying two months and a half, and even three 

 months. 



" 9. The assertion of Dr Willems that the beasts which had 

 been inoculated fattened more readily, and furnished more milk 

 than others who had not undergone inoculation, appears to be 

 confirmed by some distillers at Hasselt. 



" 10. Four calves inoculated by the Belgian commission fell 

 victims to the articular synovitis of calves, after inocidation ; 

 and the inoculation of a cow at the school at Brussels, was 

 followed by the eruption of a dartrous affection of an extensive 

 character. Dr Ulrich makes mention of these facts by way of 

 record, without considering them absolute sequelre of inocula- 

 tion. These various results springing from inoculation, which 

 have come to the knowledge of M. Ulrich, do not appear to be 

 of a nature to permit him to pronounce definitely on the value 

 of inoculation for pleuro-pneumonia, since by the side of facts 

 in favour of it, come others militating against it, and especially 

 since it has not yet been demonstratively shown that beasts 

 inoculated and exposed to the natural contagion for a space of 

 time, of sufficient and satisfactory length, have remained uncon- 

 taminated. To prove this some direct experiments must be 

 instituted. Afterwards, Dr Ulrich informs us that the Belgic 

 commission have already entered on the undertaking ; and to 

 settle the point, have instituted a series of direct experiments, 

 while similar experiments are about being made in Holland 

 and in France. In France, he says, a committee well qualified 

 for it have taken uj) the question anew of the contagion of pleuro- 

 pneumonia, since even up to this day its contagious pro- 

 perty has been questioned in France, tliough fresh experiments 

 have convinced them of it. In regard to M. Willems' o]3iuion
