into the work, it is for palaeontologists to see that he is enabled to 

 complete it. 



Mr. Buckraan's procedure is to print the original diagnosis, to give 

 additional details, and then to discuss and amplify them, recording 

 his result in a final paragraph fixing the nomenclature. Such work 

 is of the highest possible value, for until we have cleared up and 

 fixed old types it is merely beating the air to describe new ones. 



We are glad to see that the author tabulates and explains once 

 more his terminology and his zones, as that renders his position and 

 work quite clear and comprehensive. 



For Mr. Tutcher's photographs we have nothing but praise. With 

 a critical knowledge of the forms and tlieir details, he has mastered 

 his art, and the . combined efforts of the two friends has laid all 

 students of the Ammonites under a great debt. More subscribers are, 

 however, needed to push the work forward to amorei'apid completion.

1. ToEKSHiRE Philosophical Society. — The Annual Report of this 

 Society for 1912 contains a notice of the building of a new lecture 

 theatre, erected by the influence of the President, Dr. Tempest 

 Anderson, and formally opened by Professor T. G. Bonney, F.R.S., 

 who delivered a discourse on the "Development of Education ". 



2. Cambridge Philosophical SociETr. — To the Proceedings of this 

 Society (vol. xvii, 1913) Mr. R. H. Rastall has contributed notes on 

 "The Mineral Composition of some Cambridgeshire Sands and 

 Gravels", including Plateau and River Gravels and wind-drifted 

 surface-deposits. While the most abundant material in all the sands 

 is naturally quartz, it is interesting to find that " next in abundance 

 is flint in white opaque grains, often well rounded". Other minerals 

 are glauconile, tourmaline, kyanite, staurolite, garnet, hornblende, 

 augite, hypersthene, and epidote, while there is an almost complete 

 absence of muscovite. The author concludes that "the materials 

 have been derived from two' sources, pai'tly from the Neocomian sands 

 of Cambridgeshire and the neighbourhood of the Wash, and partly 

 from far-distant sources by ice-transit, that is, from the solid matter 

 transported on and in the ice from Norway, Scotland, and the north 

 of England ". In another paper on "The Minerals of some Sands 

 and Gravels near Newmarket" the most notable heavy minerals 

 recorded are zircon andrutile, while kyanite, staurolite, and tourmaline 

 are rare or absent. Moreover, in certain beds of loam and marl 

 muscovite proved to be abundant. 



3. South African Vertebrata. — In the Annals of the South African 

 Museum (vol. vii, 1912) Dr. R. Broom describes a new species of 

 Propappus, and expresses his opinion that tliis genus and the allied 

 Pareiasaurtis "were heavily built animals which probably walked 

 with slow, deliberate movements, such as we see in the large tortoises. 

 They were land animals, and it seems more likely that they lived 

 even on the dry land than that they frequented the marshes. The 

 structure of the claws and the humerus would seem to indicate that 

 they were digging animals, and probably, like the Echidna, they
