professor, that when I manil)ulated I had some means of increasing its friction, whereby I couht control the amont of fi'iction. I asked him how ? For instance, he said~ it is quite possible for the ball to be nmde with two holes in it, one passing through the axis of the sphere in a right line, and a second hole with its ends terminating in the straight hole, but the course of the second hole being made curved or crooked, then when the cord was threaded through the curved or crooked passageway, the fi'ietion conld be eol~trolled by the more or less tension of the cord. This was the true solution of the trick, for trick it was and is. A trick perhaps thmillar to many of you, but interesting as a very clever device fbr testing the inventive thculty of those who see it for the first thne.
Apart from the mechanical problems involved in the apparatus there is of course required the sldll of hand, that enables the cord to be threaded into either one of the two passages, without any seeming hesitation in the simple act of threading the ball into the cord. There is a great deal of superstition hiding in all our minds and we are too apt to credit with some.supernatural significance occurrances that are simple enough when we come to see them in the proper light. The training of the young should be more in the direction of a development of the inventive faculties, not to make an inventor of the grown up child, but to teach him how to view all things dispationately.
Lectures can do but a small point of this instruction, books must do more, and the public sclmols must be made to do their full share of the work of training, the hands, as well as the head. Under the wise direction of the present superintendent of t~ublie schools, we look {or much good in this direction. It is our earnest hope that the present course of lectures may not only interest, but serve to illustrate what should be taught.
Cleansing Old Paintings--M. de Bibra begins by removing tile dust, with a brush, and washing with a sponge dipped in imre water. The surface of the picture is then covered with a thick layer of soap, which is removed after eight or ten minutes by a hard brush and water. After the last traces of soap are removed tile picture is thoroughly dried, and rubbed with linen rags dipped in nitro-benzine. The cleansing is complete when the rags cease to be soiled. Aider again drying, tho. painting is covered with fine olive oil and varnished.
