I Preface to March 25. 1677.

I Have little to say for a Preface to this my Twelfth Volume (which by the Divine Assistance I now begin:) For that so many of the chief Universities in Christendom have already formed themselves into Philosophical Societies; and have largely contributed their Aydes to advance the Lord Bacons Design for the Instauration of Arts and Sciences, that it is now become above my abilities to direct or propose those rare and excellent things, which are suggested to many worthy Authors by their own happy Genius.
