He was impressed with the idea that life was a slow-burning flame, and he often pointed out the analogy between living processes and the burning of a candle. It was in the present tract, however that he gave special attention to the theme, insisting upon the term flamma vitalis (pp.105 et seq). In many places he approached the modern theory of oxidation" [Fulton].
While the book was in the press Boyle as an afterthought decided to add more material. This was to be be inserted in middle of sheets already printed and this has resulted in an interrupted sequence of gatherings with almost 200 pages introduced between leaves K1 and K2 and with the gathering x (the last of the of extra material) coming long before gathering P, the last gathering of the book proper. The book was reissued in 1673 with a cancelled title page dated for that year.
