Excerpt: Case XVI and Case XVII, complete, pp. 31-35 of Edward Jenner, An Inquiry into the Causes and Effects of the Variolæ Vaccinæ (London, printed for the author by Sampson Low, 1798), with Plate No. 1, which Case XVI annexes. Text of the English Wikisource, whose pages of this part are all validated (level 4), from File:An Inquiry into the Causes and Effects of the Variolæ Vaccinæ - 1798.djvu on Wikimedia Commons, the Internet Archive scan b24759247 of the copy of the London School of Hygiene & Tropical Medicine Library; checked word by word against the page images of that scan. As in the transcription, the long s is set as s, the ligature ct as c t, and the spaces before ; are not kept; words hyphenated at line ends are joined; running heads, page numbers, catchwords and signature marks are left out. The footnote marked with an asterisk is numbered and set after the text. The case headings keep their capitals, set in the heading style of the poster. The rest of the book (the other cases and Jenner’s discussion) is left out. Plate No. 1: File:An Inquiry Into the Causes and Effects of the Variolæ Vaccinæ (1798) - illustration - No. 1.png on Wikimedia Commons (3976 x 1636 px), the plate extracted from the same Internet Archive scan (its file page credits archive.org/details/b24759247), saved as JPEG for the poster; its number and the engraver’s line, which the file leaves out, are given in the caption as engraved.
