Excerpt from Lectures on the Physiology of Plants English language treating at all fully of the Physiology of Plants, so as to meet the requirements of advanced students, suggested to me, at an early stage in my career as a teacher of the subject, that I should publish my own lecture-notes just sufficiently expanded to make them readable. Of this suggestion, this volume is the outcome. The work of preparation began in 1877, but, on account of the pressure of other duties, it was not until 1882 that it had proceeded far enough to warrant going to press. I hoped at that time to have completed the Lectures within a twelvemonth at longest, but failing health and increasing demands upon my time have extended the period to four years. In consequence of this delay, it will be found that in the earlier Lectures the most recent researches have not been noticed. There will, I hope, be an opportunity to remedy this defect in a subsequent edition. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
