RECENT ADVANCES IN SCIENCE 479 



it was responsible for planting the germs of the remarkable 

 Pre-Columbian civilisation." Another paper on the same 

 subject by Prof. Elliot Smith may be mentioned, namely, 

 " The Origin of the Pre-Columbian Civilisation of America," 

 in Science for August 11, 19 16. Much of the evidence adduced 

 by the author of these papers appears to me to be of a con- 

 vincing character. 



The reader who is interested in the spread of the Egyptian, 

 Phoenician, and other ancient civilisations should also read 

 two recent papers by Mr. W. J. Perry. These are " The 

 Relationship between the Geographical Distribution of Mega- 

 lithic Monuments and Ancient Mines " in vol. lx., Part I. of 

 the Memoirs and Proceedings of the Manchester Literary and 

 Philosophical Society, and " The Geographical Distribution of 

 Terraced Cultivation and Irrigation " in the same Memoirs, 

 vol. lx. Part I. 



To Parts II. and III. of the same volume of these Manchester 

 Memoirs, a whole series of papers dealing with different aspects 

 of this same problem is contributed by Mr. J. Wilfrid Jackson. 

 Of these papers one of the most interesting, though not the 

 longest, is " The Aztec Moon-cult and its relation to the Chank- 

 cult of India." 



The Proceedings of the now well-known Prehistoric Society 

 of East Anglia for the year 191 5-16 have been recently 

 published. The Proceedings are largely composed of reports 

 upon and discussions about the discoveries made at Grime's 

 Graves. I have alluded to these discoveries in previous numbers 

 of this Review. In particular, the volume now received 

 includes the Presidential Address of Mr. A. E. Peake, dealing 

 with the Grime's Graves, and Mr. A. S. Kennard's paper on the 

 " Pleistocene Succession in England," to both of which I 

 referred in the July number of Science Progress. Both these 

 papers are extremely controversial. I notice in passing that 

 Mr. Kennard throws in some jibes at German science which 

 are not only somewhat out of place in a learned society, even in 

 war, but have not the merit of being true. Even now, the 

 people of this country do not properly appreciate the fact that 

 the remarkable strength displayed by the German nation during 

 the last thirty months has been very largely the power of 

 German science. Failing a much more adequate cultivation 

 of science, there will be no great future for Great Britain.
