PUERING, BATING, AND DRENCHING OF SKINS CHAPTER I. THE PUERING AND BATING PROCESS. In this e-book a black underline indicates a hyperlink to a page, illustration or footnote (hyperlinks are also highlighted when the mouse pointer hovers over them), and a red dashed underline indicates the presence of a concealed comment which can be viewed by hovering the mouse pointer over the underlined text. Page numbers are shown in the right margin and footnotes are at the end. Footnotes are listed at the end. The text contains tables, equations and chemical formulae that might not display correctly on small reading devices – a standard web browser is recommended. The text of the book has mostly been preserved in its original form, including inconsistent italics, capitalisation, and hyphenation. However, some defects have been corrected silently, such as missing/inconsistent punctuation, parentheses and spacing, and an erroneous ÷ has been replaced by − in a fraction in footnote 69. Tables have been formatted to match the originals, but a large table that was originally split over four pages (pp. 98–101), has been condensed into two sections. Some illustrations have been positioned closer to the relevant text and the location may not correspond to that specified in the list of illustrations. The following typographic corrections have been made: The following inconsistent spellings have not been altered: The cover image of the book was created by the transcriber and is placed in the public domain. THE Scientia et potentia humana in idem coincidunt, quia ignoratio causÆ destituit effectum. Natura enim non nisi parendo vincitur: et quod in contemplatione instar causÆ est, id in operatione instar regulÆ est. Knowledge and human power are synonymous, since the ignorance of the cause frustrates the effect; for nature is only subdued by submission, and that, which in contemplative philosophy corresponds with the cause, in practical science becomes the rule.—Bacon, Aphorism III.
