| Transcriber's Note |
| |
| Transliterations: The original book used a number of special |
| characters. Most have been replaced by obvious text equivalents. |
| The Greek phrase on the title page has been transliterated. |
| The book also used special symbols for planets, etc; this |
| version renders these in capitals surrounded by square brackets, |
| e.g. [NEPTUNE]. [VOLCANO] represents an unknown planet, in the |
| original denoted by a right-angled triangle which the author |
| wrote represented a volcano. |
| The degree symbol is here rendered as d. It is hoped that no |
| confusion will result from the author's use of "2d" and "3d" for |
| "second" and "third". |
| The plus-or-minus sign is rendered +/-. |
| |
| The ISO-8859-1 text version preserves more symbols, including |
| the latter two. The UTF-8 text and HTML versions preserve all of |
| the symbols originally used. |
| |
| Printer errors: Obvious typographical errors in the original |
| have been corrected in this version, and full details of the |
| corrections can be found in the HTML version of this ebook. |
| However, the inconsistent spelling of Ottawa/Ottowa, and the |
| inconsistent use of comma or full-stop as thousands separator |
| has been left as in the original. The value given for the |
| eccentricity of Uranus may also be a printer error. |
