It gives me real concern to find, on reading the book you favoured me with, that you meet with such opposition in the practice of inoculation, notwithstanding it is so apparently beneficial to mankind; and particularly, that gentlemen of the first rank in the medical profession, should find it so difficult to divest themselves of unreasonable prejudices: but in the end truth will prevail. I am, Sir, Your most obedient humble servant, T. DIMSDALE. A Copy. Berlin, 24th March, 1777. Dear Sir, Your kind letter of the 10th instant, for which I owe you the greatest obligation, arrived here by the last post; and I am truly grieved to find so material a perversion and misrepresentation of your just opinion on the case of young Blumenthal, as is made in the French translation of it. In apology for which, I have only to say, that as I am not sufficiently master of the French to publish in that language, I put my English manuscript into the hands of a gentleman, an intimate friend, who is distinguishedly eminent for his knowledge, both of French and English, and who was formerly, for some time, a most eminent preacher, in London, to the French refugees; so that I had no doubt of his capacity or attention to do the whole justice, and therefore trusted it to him, with a most strict injunction, whatever liberties he took in other parts, to be particularly exact in translating the letters, and quotations, without varying the sense of them in any part, for the sake of being florid.

I have the pleasure to add, that in the German translation, which has been sometime published, and which are all sold, the error has not been committed, and the translation of your letter is literal and exact. And as both the German and French are but translations of the original, further to secure the whole from being misunderstood, if you think that
