Or did grad mean something different in Tudor and Stuart times?
In Portuguese the same word "gradus" begot both "grau" (degree) and "gradus" (360 and 400 units). So maybe *that* G was "gradus" which by the time probabily meant "degree", not what we nowadays know as "grad". This specalution could very easily be tested with a book on History of math, or an encyclopaedia neither of which I have right now. - fernando -- REDUZIR, REUSAR, RECICLAR -- Dever de todos, amor aos que virão REDUCE, REUSE, RECYCLE -- Everybody's duty, love to those who are to come Fernando Cabral Padrao iX Sistemas Abertos mailto:[EMAIL PROTECTED] http://www.pix.com.br Fone Direto: +55 61 329-0206 mailto:[EMAIL PROTECTED] PABX: +55 61 329-0202 Fax: +55 61 326-3082 15º 45' 04.9" S (23 L 0196446/8256520) 47º 49' 58.6" W 19º 37' 57.0" S (23 K 0469898/7829161) 45º 17' 13.6" W
