    2. B. When a new thought is added to what precedes, as an enlargement of it, it is introduced by adde, adde huc, adde quod, and the like (cf. accedo), add to this, add to this the circumstance that, or besides, moreover . . .: adde furorem animi proprium atque oblivia rerum, adde quod in nigras lethargi mergitur undas, Lucr. 3, 828 sq.
