A good deal of time on one day was occupied by a discussion upon animals and plants; but as several of those who took part in the discussion did not wish their remarks to be reported, it has been thought better to leave out this part of the proceedings of Seetion D. Botanical papers preponderated over zoological, but it was not found necessary to divide the Section into two sub-Sections.
