The passion for inoculation as a safeguard against all sorts
of diseases is certainly on the increase, but we doubt whether the evidence be, on the whole, favourable to that kind of safeguard. In a recent case in Cumberland, forty-nine cattle were inocu- lated with pleuro-pneumonia about three weeks ago, and of these, forty-six are doing well, though there is, of course, nothing to prove that they are doing better than they would have done, had no inoculation taken place. The other three fell dangerously ill ; one died, and the other two were slaughtered, the lungs being in each of these two eases found healthy, while other organs were affected much as the lungs of cattle attacked by pleuro-pneamonia are usually affected. We should expect that the issue of the experiment will not do much to advance inoculation with plenro-pneamonia in the favour of cattle-owners.
