practising upon the faith of others, had they been authoritatively held up before him. 9. Instances of this kind are far from uncommon. Men who are old enough, will remember the trouble which came upon a person, eminent as a professional man in London even at that distant day, and still more eminent since, in consequence of his publishing a book in which he so treated the subject of Comparative Anatomy as to seem to deny the immateriality of the soul. I speak here neither as excusing nor reprobating sentiments about which I have not the means of forming a judgment; all indeed I have heard of him makes me mention him with interest and respect; anyhow of this I am sure, that if there be a calling which feels its position and its dignity to lie in abstaining from controversy and in cultivating kindly feelings with men of all opinions, it is the medical profession, and I cannot believe that the person in question would purposely have raised the indignation and incurred the censure of the religious public. What then must have been his fault or mistake, but that he unsuspiciously threw himself upon his own particular science, which is of a material character, and allowed it to carry him forward into a subject-matter, where it had no right to give the law, viz., that of spiritual beings, which directly belongs to the science of Theology? Another instance occurred at a later date. A living dignitary of the Established Church wrote a History of the Jews; in which, with what I consider at least bad judgment, he took an external view of it, and hence was led to assimilate it as nearly as possible to secular history. A great sensation was the consequence among the members of his own communion, from which he still suffers. Arguing from the dislike and contempt of polemical demonstrations which that accomplished writer has ever shown, I must conclude that he was simply betrayed into a false step by the treacherous fascination of what is called the Philosophy of History, which is good in its place, but can scarcely be applied in cases where the Almighty has superseded the natural laws of society and history. From this he would have been saved, had he been a Catholic; but in the Establishment he knew of no teaching, to which he was bound to defer, which might rule that to be false which attracted him by its speciousness. 10.
