 Port Natal. He hoped to have the company of Captain 

 Palliser, 1 and would be glad if men of science would suggest 

 matter deserving investigation. 



On April 20th, the I02nd meeting, Dr. Gassiot exhibited 

 a photograph of spots on the sun, taken at Kew with the 

 photoheliograph on March I5th last, which showed that 

 the principal difficulties in manipulation had been sur- 

 mounted. 



Professor Tyndall stated that he had found by experiments 

 that the readiness with which liquids assume a spheroidal

 and this, when of low intensity, is readily arrested in those 

 into the composition of which hydrogen enters. 



Dr. Hooker said that Dr. Livingstone, writing from Sierra
