Digitized by Google 314 THE MODERfiT ASTRONOMY, &C. in a warm climate, baring been between forty and fifty yearg in India, obliges me to lay down my pen, imd to desist from all further investigations : indeed it has been with a great deal of difficulty that I have brought this essay to a close, in the state it is in. If my health had permitted, it might have been made more perfect and full ; but on this account I have been obliged to curtail it, and leave out many things that might be useful. However, though thus nar rowed, I believe the astronomer and man of science will still find all ttet he may require, or that is ab- scdutely necessary, for formmg^ a just idea of the ^indu astronomy, and its antiquity.
