ABERDEEN: THE UNIVERSITY PRESS
TRANSCRIBER'S NOTE:
With a few exceptions, original spelling and grammar were retained. The cover image is a modified version of the original scanned image from archive.org.
This book contains several uncommon Unicode characters, including "→", "↓", "⇌", "⇅", "│", "╱", "╲", "═", "║". A font and ebook reader software capable of rendering these is necessary for reading this book.
Full stops, middle dots "·", or even "˙"—Dot Above"—were variably (randomly?) used in the original as decimal points and for denoting chemical bonds. These have been rendered as middle dots herein.
The reference to Colin's paper on [page 5] has been changed from 1826 to 1825, to agree with the corresponding entry in the Bibliography. The reference to Turpin's paper on [page 8] was changed to 1838 from 1839, for the same reason.
Tables and formulas have been edited for clarity and readability, while honoring the original form. For example, the two sequential equations at the top of [page 110] originally had "+O" and "−H2O" written under the two arrows, and the two equations appeared on one line. These have been converted into two equations on two lines, with the arrow subtext moved into the equations.
The incorrect formula for the enol II. in the equation for Glucose dehydration near bottom of [page 101] was corrected.
