The original spellings and gramatical constructs have been preserved as far as possible. With the exception of the typographical corrections detailed below, the text is that published in the original document. The image captions were moved directly below its image from the bottom of each page.
Images were placed in approximately the same location as in the original text. Figure 177 was rotated 90° as it fit better in this version and the lettering suggests that it may have originally been intended to be presented in this orientation. The image sizes vary from that of the original printed volume and so any notation retained from the original text regarding the same may not be accurate. Variations in the display properties of various monitors and user preferences would tend to also result in images which are not to scale with the original printed version.
