Transcriber’s Notes
Depending on the hard- and software used to read this text and their settins, not all elements may displayed as intended.
Archaic, unusual and inconsistent spelling, grammar and sentence constructions have been retained; accents etc. for French and German have not been corrected unless listed below.
Paragraph numbering has been retained, also when this was not serving any obvious purpose and/or was not contiguous.
The use of italicised and non-italicised reference letters in the text has not been standardised.
The hierarchy in (sub-)section headings has been based on the text, due to the absence of a detailed table of contents and lack of visible differences between the various levels of (sub-)section headings in the source document.
The plates were originally bound separate from the text, but in the source document used they were bound together with the text. Due to the way of binding parts of most plates are invisible and discoloured near and in the gutter. Captions and credits in and around the plates have been reconstructed as far as possible.
Larger versions of the plates may not be available in all file formats, but may be accessed through the browser version available at www.gutenberg.org. In the descriptions of individual items hyperlinks have only been provided to the Plates, not to individual figures in the plates.

Page 205, They first fold back the parts A B: the reference letters are not present in the drawing.
Page 352, Skin of the lump sucker: Plate XVIII. Fig. 7 falls in the gutter of the plate, and has no caption.
Page 446, E. eliptica: eliptica and elliptica were both used.
Page 623, the blea, the bark, and the wood: as printed in the source document.

Changes made
Footnotes have been moved to under the text to which they belong. Where necessary, page numbers in references to footnotes have been adjusted accordingly.
