Proceedings. 95 



Ordinary Meeting, March 3rd, 1896. 

 Henry Wilde, F.R.S., President, in the Chair. 



The thanks of the meeting were voted to the donors 

 of the books upon the table. 



Professor Schuster, F.R.S., gave an account of 

 experiments which have been carried on in the Physical 

 Laboratory of the Johns Hopkins University, showing the 

 shifting of the lines in the spectrum of a metal due to 

 pressure ; and also exhibited photographs taken by means 

 of the Rontgen rays of a child's hand and of the leg of 

 a frog, which latter showed that the leg had been broken 

 and had healed. 



Mr. D. E. Packer gave a supplementary account of 

 his attempts to photograph the sun's corona by means 

 of a pin-hole camera with metallic screens over the 

 sensitive plate, and exhibited further photographs of the 

 results obtained. , 



Ordinary Meeting, March 17th, 1896. 



Professor Osborne Reynolds, M.A., LL.D, F.R.S., 

 Vice-President, in the Chair. 



The thanks of the members were voted to the donors 

 of the books upon the table. 



Dr. Schuster, F.R.S., warned the members against 

 placing too much reliance on published experiments with 

 the Rontgen rays, on the ground that many single 

 observations made known had not been confirmed by 

 further investigations. Conclusions have been too hastily 

 drawn, and, therefore, have not been subsequently justified. 

 It seems, however, to be established that there is an 

 accumulation of evidence of a real state of oscillatory 

 motion ; and that there may be a kind of phosphorescence,
