“_In some cases the vaccinated calves have suffered from diarrhœa_.” At page 178, “In Depaul’s seventh and eighth experiments, for example, _the calves suffered severely from diarrhœa_.” Another passage, page 178, shows that diarrhœa is an accompaniment of the process; “the health of the calf, however, affects the character of the eruption, for it has been observed that _when diarrhœa happens in the course of its evolution_, the pustules, although they rise as in the healthy calf, are smaller in size, and less full.” And thus infant mortality is increased by the infliction of a disease of the brute creation, which in the “course of its evolution,” causes diarrhœa. The medical press has lately teemed with articles calling attention to the prevalence of small-pox, in Paris, it is stated that small-pox prevails there because vaccination is not compulsory. While it is quite true that the Legislature of Prance has passed no such disgraceful and tyrannical vaccination acts, as those which exist in England,—yet vaccination is almost universally adopted. Mr. Smee, the surgeon to the Bank of England, and examiner of candidates for life assurance, lately, in a letter to the “Times” newspaper, stated that his large experience enabled him to state that to find a Frenchman unvaccinated was an exception. The 12th report of the medical officer of the Privy Council tells us that in France it has been decreed, under the direction of the Academy of Medicine, by ministers, that “No infant should enter an orphan asylum, an hospital, a primary school, a lyceum, or a government college without a certificate, of vaccination.” The Army and Navy of France are vaccinated, and vaccination is enjoined, if not enforced, on all who hold government situations. Besides this, it is forced upon the poor by a rule that “_those who refuse to have their children vaccinated_, _shall have no public assistance_.” The fact is, that vaccination has failed in Paris, as in every other city. Let the medical gentlemen opposite, look to the paper of Dr. Seaton, whose cooked statistics they have quoted to-night; the paper to which I have before alluded, presented to the Lords of the Privy Council in the 12th report of Mr. Simon, and at page 188, they will find the following passage:— “Striking exemplification of the danger of confiding in animal vaccination during an outbreak of small-pox has been given during the present epidemic in Paris, no doubt a large share of the _unsuccess_ which has _notoriously_ attended the practice, has been due to the hurry, and other unfavorable conditions under which it has been carried on. _But apart from this_, _and where the conditions have been favorable_, THE FAILURES HAVE BEEN QUITE REMARKABLE.”
