Publisher's Synopsis
Excerpt from The After-Image Threshold
Experiments were also made on the intensive effect of the weight as compared to that; of the velocity. A 100 g. Weight having fallen upon the hand from a height of 5 cm., the height was found at which 25 g would cause a sensation of the same intensity. Here also o'bservers differed greatly. The average height for 5 observers was 38 cm., the maxi mum being.58, the minimum 20 cm. It Hence the mass has in general greater intensive effect than the height or the square of the velocity. Otherwise the average height found would be about 20 cm. On the other hand, the mass has less effect than the velocity or square root of the height.
