age, often converted into marble, which rest, and in some casea 

 are enclosed in, igneous rocks. Tliey occur in the Tibetan area. 

 These blocks would appear to be the result of the action of huge 

 igneous flows, which, passing through the dislocated rocks, toi'e off 

 and bore to the surface masses of rudimentary rock, together with 

 other loose masses, the result of the dislocating and faulting itself. 

 Dr. Griesbach thinks that all this was part of the general Himalayan 

 upheaval, which falls into the period after the deposition of the 

 Upper Cretaceous system and prior to the deposition of the younger 

 Tertiaries, and fits into the period during which the great flows of 

 Dekkan Trap took place in India. 



16. Beadford Glacial Lakes. — The Bradford Scientific Associa- 

 tion have started a new quarterly called the Bradford Scientific Journal 

 (No. 1, July 1904), and the opening paper deals with "The Glacial 

 Lakes of the Bradford District," by J. E. Wilson, The author 

 gives a map, and states that a note of his conclusions appeared in 

 the Report of the British Association for 1900. 



17. Persimmon Creek Meteorite. — This iron came from North 

 Carolina in 1893, and is now in the U.S. National Museum. It is 

 described in the Proc. U.S. Nat. Mus., xxvii (1904), by Wirt Tassin, 

 as "a more or less continuous matrix of iron containing troilite, 

 schreibersite, and carbon." Its present weight is 9 lb. 6 oz., but 

 a fragment weighing about 1 lb, 13 oz, has been broken off, 



18. Museums, — It may be well to call attention to the Vorberichte 

 fiir die xii Konferenz (Centralstelle fiir Arbeiter - Wohlfahrtsein- 

 richtungen), 1903, in Mannheim, which contains Gill Parker's 

 account of the Euskin Museum and Lehmann's account of the 

 Altona Museum, among other papers, 



19. Fresh Fossil Egg.— Messrs. W, C. Morgan and M. C. Tallman 

 described in Bull. Geol. Univ, Calif. Publications (iii, 1904) an egg 

 from a pebble in a placer deposit on the Gila river in Arizona. 

 The egg formed the centre of a rounded mass of hard calcareous 

 rock, which was removed so as to allow of an examination of a fresh 

 surface of the shell. The authors say that the egg corresponds 

 fairly well to the type of egg laid by a cormorant, and with that 

 and some photographic illustrations we must content ourselves. 



20. Erratic Blocks. — Si^ecial attention should be called to tlie 

 Eighth Report of the Committee on the Erratic Blocks of the British 

 Isles (Rep, Brit, Assoc, for 1903, 1904), as in it the Secretary, 

 Professor Percy F. Kendall, has drawn up a summary of the records 

 accumulated during the past thirty-two years from England, Wales, 

 the Isle of Man, and Scotland, 



21. The "Records of the Geological Survey of India," established 

 in 1868, published hitherto in yearly volumes until 1897, when it 

 was amalgamated with the " Memoirs." With a view to the rapid 

 publication of short papers and notes on Indian geology, it is now 

 being continued again as before. Private workers are invited to 

 contribute. The current number (vol. xxxi, pt. 1, 1904) contains
