Ixxii. PRESIDENT'S ADDRESS. 



preserve such an interesting object to the world. Some crystals 

 of immense size, including one of smoky quartz, weighing 6oolb., 

 have lately been found in Texas, and, not being of such great 

 value, will, I hope, be preserved intact in some museum. The 

 value of gold obtained from Merionethshire in 1904 was 

 ;?3>9 2 5 nearly four times that in 1903. 



The recent expedition to Tibet has thrown some light on the 

 geology of that country. Marine Tertiary beds occur north of 

 the Sikkim border; and there is evidence of a former consider- 

 able extension of glaciers northward from the Himalayas, 

 Granite near Lhasa is intrusive in Jurassic strata, and minerals 

 and gems are scarce. 



Our hon. member, Mr. Jukes Browne, confirms the theory of 

 the derivation of clay-with-flints from Eocene strata, and not 

 from the chalk, as hitherto believed. 



A rich Cambrian fauna from China has been collected and 

 described by the Washington Carnegie Institution. 



In the British Museum (Natural History) one of the most 

 valuable and interesting additions in the past year is the full- 

 sized model of the gigantic dinosaur, about 85 feet in length, 

 Diplodocus Carnegii, presented by Mr. Carnegie, whose public 

 spirit has been so munificently shown both in this country and 

 in America. The restorations of extinct monsters at the Crystal 

 Palace of fifty years ago have served their purpose, and have to 

 give way to the beautiful fossils and accurate restorations which 

 are now such a feature of the American museums, and which 

 have been chiefly obtained in the Upper Jurassic beds of 

 Wyoming and Colorado. Triceratops, with an enormous horned 

 skull nearly a third of its total length, is one of the more recent 

 additions. 



Valuable palaeontological discoveries have been made in the 

 Eocene beds of the Fayum province of Egypt, which have 

 yielded mammalian fossils in abundance, throwing much light 

 on the ancestry of the Proboscidea. The remains of fish and 

 crocodiles have also been found in this area, which consists 

 chiefly of desert, though part is cultivated by irrigation.
