Inoculation for Pleuro- Pneumonia in Cattle. 249 



have really seen," says Mr. Curtis, "such extraordinary effects follow 

 inoculation, and have also seen scientific men of the highest standing who 

 opposed the system for a long time become complete converts to inoculation, that 

 I can no longer doubt, and consequently I am an advocate of the system. 



"The Prussian Government, who, as you truly remark in your Report,* 

 ordered the operations of M. de Saive to be discontinued last year, are also 

 amongst the convei'ts, and inoculation is encouraged by every means by the 

 Government." 



Besides the inquiries of Dr. Ulrich in Belgium, it appears 

 from some reports with which we are just favoured by Mr. He- 

 beler, the Consul-General of Prussia, that Dr. Liidersdorff of 

 Berlin has also investigated the subject of cattle inoculation in 

 the Cologne district. This step was rendered the more necessary 

 from the ill success of Dr. De Salve's operations last year. Dr. 

 Liidersdorff concludes his Report by stating that, " although his 

 observations are perhaps not fully conclusive, still they certainly 

 speak more in favour of than against inoculation. They show 

 that the danger of this remedy is in no proportion to the losses 

 produced by the natural disease, and that consequently inocu- 

 lation should be more generally adopted." A committee of the 

 Agricultural Society of Ober-Bamein district also reported that 

 " Dr. Willem's plan of operating can be so improved as to avoid 

 the ill consequences at present attending it." 



Prussia, we thus see, has been induced to follow in the wake 

 of Holland, by adopting inoculation as a means to save her cattle 

 from the ravages of Pleuro-pneumonia. 



As yet we are without direct or official information from 

 France, and, therefore, we must not anticipate the opinions of 

 her Commissioners being in favour or otherwise of the practice 

 by any speculations of our own. It is probable that their 

 Report may come to hand in time for the particulars to be in- 

 serted in the present paper ; and if so, they will be given, so as 

 to render the subject as complete as it can be under existing 

 circumstances. Failing this information for the present, we 

 come next to the proceedings of Belgium herself. 



The Commissioners here have spared no pains to arrive at 

 the true value of the practice of inoculation, and their Report, 

 which extends over 176 pages 8vo., is full of most interesting 

 and valuable details. In the majority of cases their experience 

 fully coincides with our own, a fact to which we allude, in order 

 to show the impartiality of their proceedings, and which we 

 regret to see has been called in question. It is unnecessary to 

 select cases from their Report, or to follow the Commissioners 

 through their scientific reasonings on the subject ; and, there- 

 fore, we shall in this place content ourselves by giving the con- 

 clusions to which they have arrived.
