10 PRESIDENT'S ADDRESS. 



Coleoptera, Hemiptera, and others, as well as the wing of a 

 doubtful Lepidopt^ron. One huge Protorthopteron has a 

 wing measuring 9in. by 3in., and was, I suppose, a sort of 

 gigantic locust. There is also a fossil Tiiassic dragonfly. 

 A third species of tsetse-fly, beautifully preserved, has also 

 been found in Miocene shales in Colorado, where I believe 

 many fossil insects have occurred. Either the quality of the 

 rock, or the circumstances under which it was laid down, 

 makes these delicate fossils rare in most strata. A new 

 Dinosaur (Struthiomimus) has been received by the American 

 Museum of Natural History from the Cretaceous beds of 

 Alberta. It has a small head, toothless jaws, sheathed 

 doubtless in narrow beaks, a long neck, and a backbone 

 13 feet long, short fore and long hind limbs, and probably 

 somewhat resembled an ostrich in its mode of life, though 

 it was not a bird. Another Dinosaur ( Corythosaurus casuarius) 

 from the same source has also been added to the same 

 Museum. This is about 20 feet long, and has a high, rounded 

 bony crest on its head and its skin covered with tubercles. 

 Some portions of the jaws and head of a mammal (Eodelphis 

 Browni) from the same source and in the same museum, 

 though very fragmentary, form the most complete Cretaceous 

 mammalian remains yet discovered. It seems a pity that 

 these interesting fossils from British territory should not 

 find a home in a British Museum. Now that the conquest 

 of German East Africa is practically complete, it is to be 

 hoped that our museums will before long acquire some of 

 the wonderful fossils found in that region. 



ASTRONOMY. 



A work of much interest to Astronomers has lately been 

 published, viz. : Ptolemy's Catalogue of Stars in his Almagest 

 written about 100 A.D. For this Edition numerous MSS. 

 have been consulted, so that it is probably a fairly correct
