In one such case, when he had taken away the counterpoise, he saw the spider descend by the ver- tical thread to ascertain what had happened, and, having ar- rived at the ground, she fastened the line to another pebble. It will be observed in this case that the pebble to which the thread was fastened lay upon the ground, and this fact itself compels me to doubt Professor Pavesi's conclusion. I cannot resist the thought that in this, as in other cases where the pebble was and acting as a counterpoise, it had orig- sition upon the garden path, and had of the thread, the mechanical action of spider, and the swaying of the trees, been made by Professor Parona of It- cated in a paper entitled, " A Peculiar- of Meta ;^ In October, 1886, villa at Baccione, on Lake Orta, a web spun in the entrance of a short arti- vated in solid earth.
