The appearance of the spots, is such as might be reasonably expected on any person who died of a malignant fever. Dry scabs frequently remain on the inoculated parts, for some months after the disease. T. DIMSDALE. To Dr. Baylies, Physician and Privy-Counsellor to his Prussian Majesty at Berlin. London, March 10, 1777. Dear Sir, Please to accept my thanks for a very polite letter and a book, both which I received from my learned friend, Dr. Watson. But I am greatly chagrined to find, on the perusal of the French translation of my answers to the queries, that by the insertion of words, not to be found in what I wrote, not only the sense of my answer is perverted, but I am made to speak what is not true, and to give an opinion contrary to my own sentiments, and the experience of every one in the least acquainted with the small-pox. What follows will convince you, Sir, that my complaint is well founded, and I confide in your honour, for taking the most effectual steps to prevent the injury my character would sustain, if the mistake should not be rectified. You will please to observe, that at the conclusion of the case transmitted to me, there were three queries, to each of which I gave distinct answers. The third query is: “Or were the _pustulary eruptions_ that shewed themselves on the 12th day of the disease, a critical discharge of a putrid, or other kind of fever?” In my answer, having first remarked that the patient passed through the inoculated disease in a regular manner, I say in reply to the above-mentioned query. “After which he was seized with a disease, that I have not the least doubt was a fever of the putrid kind; but I do not think that _the pustulary eruptions_ can with propriety be deemed critical, as _they did not terminate_ the disease: I rather esteem them to have been marks or tokens of great malignity and anger.” The French translation stands thus. Q. “Ou les pustules qui ont paru le 12me jour de la maladie ont elles été l’evacuation critique d’une fievre putride, ou d’une autre espece de fievre?” Reponse. “Ce n’est qu’au bout de ce tems qu’il a été attaqué d’une maladie, que je crois, sans balancer, avoir été une espece de fievre putride. Il ne faut cependant pas, selon moi, considerer _les pustules de la petite vérole_, comme une crise, parce _qu’elle ne leve pas_ la maladie; au contraire je les regarde comme les marques d’une grande malignité et d’un grand danger, ouse trouve le patient.” The perusal of the above will certainly satisfy you of the justness of my complaint, and I shall wait with impatience for your answer, which I make no doubt will be such as is consistent with your honour and character.
