The book which gave us the word ‘bioscope’ is available to download for free from the Internet Archive. The full title of Granville Penn’s 1812 religious tract is The bioscope, or dial of life, explained. To which is added, a translation of St. Paulinus’s Epistle to Celantia, on the rule of Christian life: and an elementary view of general chronology; with a perpetual solar and lunar calendar. It’s available in DjVu (9MB), PDF (21MB) or plain text (340KB) formats. For further information on Penn’s definition of the term, see the post from 6 February 2007.
