in a spectroscopic examination of the planet Saturn, the 

 spectrum of the planet itself was not so intense as that of 

 the ring, and a dark line in the red was still more intense 

 than in the atmosphere of the earth. This fact led him to 

 infer the existence of an atmosphere around Saturn, which 

 contained a substance similar to one of those present in the 

 earth's atmosphere. 



Mr. Busk said that since the last mention of the ossiferous 

 caves on Windmill Hill, Captain Brome had discovered 

 three others, containing relics of human workmanship, the 

 entrance of one being over the edge of the cliff which rose 

 above the ' Governor's Cottage ' on the east face of the 

 plateau of Windmill Hill. This cavern contained the 

 remains of several individuals, including four nearly perfect 

 crania, and numerous implements of bone, flint, and other 

 stone. The crania were uniformly dolichocephalic, very 

 like those of the Basques at the present day, and that of 

 a specimen, seen last year by Dr. Falconer and himself at 

 Madrid, which had been found in the ancient workings of a 

 copper mine in the Asturias. We might therefore infer 

 that at the ' polished stone period ' a race, resembling the 

 existing Basques, was living all over Spain. 



Professor Ramsay announced that he was to visit Gibraltar 

 during the autumn to make a geological survey of the Rock 

 and the adjoining district. 



Mr. Busk said that after studying the fossil bones of the 

 Pigmy Elephant, brought by Captain Spratt from the 

 Zebbug Cave in Malta, he held them to represent two distinct 

 species, and not one as had hitherto been supposed. 



Oct. 26th, i68th meeting. Sir R. Murchison announced 

 that Mr. S. Baker had arrived in England, and would 

 describe to the Royal Geographical Society on Nov. i3th 

 his discovery of Lake Albert Nyanza, the basin of which lay 

 under the equator and was about 260 miles in length ; * 

 also that news had been obtained from M. De Chaillu, who 

 was then about 150 miles inland from the Gaboon and was 



1 Its existence was ascertained by Speke and Grant in 1862, but it was 

 explored by Baker (afterwards Sir S.) in 1864.
