TRANSCRIBER'S NOTE:
The author often uses the South Asian numbering system where, besides the three least significant digits of the integer part, a comma divides every two rather than every three digits (for example 10,00,000 instead of 1,000,000). All corrections are underlined with a dotted line. The original text appears when hovering the cursor over the marked text. Inconsistencies in hyphenation and spelling have not been corrected. A list of corrections to the text can be found at the [end of the document].
