March 31. 1860. Waterhouse seems to dispute that insects can judge of distance — look at springing spider they must judge — we only want to perfect that. So Melipone judges. — How they judge whether guided by size of body or by touching each other (not by eyesight) but there is only 1000 difference in diameter of common & Drone cells & this is graduated away by 5 or 6 rows of cells, so that the judgment cannot be made by particular parts of body
