EPITOME OF EVIDENCE ON PLEURO-PNEUMONIA. 269 



killed when fat. If they were lean I would isolate them subse- 

 quently. I have succeeded in reducing the excessive activity of 

 the lymph, and in diluting it to some extent with glycerine. 

 This will also keep the lymph as long as is required. I have 

 succeeded in inoculating an animal successfully after having had 

 the lymph in my possession for two years. You have got 

 the experience of the Netherlands and Denmark, which shows 

 that the very best way of dealing with pleuro-pneumonia 

 is to stamp it out. I consider inoculation is a failure. I do 

 not think that experiments require to be further tried. I 

 think that the Highland Society and the Privy Council 

 might make more close inquiry into the sources of pleviro- 

 pneumonia in this country ; and they will find that a good deal 

 of it has been brought here from Dublin and Cumberland, and 

 it is still coming. I may direct your attention to this one 

 prominent fact, that since the restrictions have been put 

 on Dublin and Cumberland, Edinburgh has been kept free, 

 leaving inoculation out of the question altogether. We have 

 no disease in Edinburgh at the present moment, and nothing 

 has been brought in for several months. There is no question 

 that the restrictions in Dublin and Cumberland have had a good 

 effect. It is exactly a repetition of what took place in regard to 

 the foot-and-mouth disease. As to restrictions, I would not 

 allow the cattle to come from any quarter where it existed — 

 such as from Dublin. They boast about the north of Ireland 

 being free from pleuro-pneumonia. You are told that in Glas- 

 gow they do not get pleuro-pneumonia from Ireland the same 

 as in Edinburgh. Cattle come to Glasgow as ^mincers, and 

 your cows mix with them coming across. They do not go 

 into byres at all in Glasgow ; they go to the slaughter-house.
