As it is commonly though not very correctly expressed, there is to be no interference. For this the sensible ap - parent magnitude of the sun, or other source of light, is an amply suf- ficient cause. At page 106 of his excellent lectures, Verdet shows that the disturb- ance from the- sun cannot be considered as a system of plane waves over a space greater than a circle of -fa of a millimetre diameter. Be- tween the vibrations at two points whose mutual distance is much greater than this, there is no permanent relation of phase. This shows that the vibrations corresponding to two holes in the imaginary screen cannot interfere regularly, but behave as if they were due to thoroughly independent sources of light. Sir W. Thomson, Pi-of. Maxwell, and Mr. Strut t made some further remarks on the subject of the paper. Mr. Maxwell then gave a description of two singular solar halos which he had recently seen; and Prof. Adams, of Bang's College, gave some additional par- ticulars in the case of one of the phenomena
