weighing 30cwt., is in the Melbourne Museum; No. 3 has dis- 

 appeared. Unlike the larger mass, No. 2 appears to have exuded 

 very little chloride of iron, and no scaling has been observed. The 

 Bendoc and Yarroweyah irons are both in the Melbourne Museum ; 

 they weighed 601b. and 21 lb., and were discovered in 1898 and 1903 

 respectively. The Kulnine iron, which weighed 122 1b., and was 

 found in 1886, is in the Adelaide Museum. A table of chemical 

 analyses and a full bibliography are given. The author concludes 

 that the obsidianites (australites), though glassy in character, are 

 undoubtedly meteoric in origin. 



2. Meteoric Irons from the Klondike Mining District, 

 Yukon. — In the Museum Bulletin No. 15 of the Geological Survey 

 of Canada (pp. 8, with 11 plates, June 30, 1915), Mr. B. A. A. 

 Johnston describes the meteoric irons found in the course of gold- 

 mining operations in Gay Gulch and Skookum Gulch, both tributary 

 to the Bonanza Creek system in the Klondike mining district, 

 Yukon. The former weighed 483 grams and was found in 1901. 

 The latter, which was discovered on January 21, 1905, was much 

 larger; it measured 29 cm. in length, 23 cm. in width, and 3 to 8 cm. 

 in thickness, and weighed 15*88 kilograms. Both specimens were 

 acquired by the Ottawa Museum. From the similarity in the 

 characters of the two irons, both being exceptionally rich in nickel 

 and exhibiting a peculiar chatoyancy in sections, and in their 

 positions, both lying on the bedrock under the ' white channel ' 

 gravels, as the miners term the ancient creek deposits, the author 

 considers that they are relics of a single meteoric shower, which 

 occurred in Tertiary time.

COAST EEOSION IN NOBFOLK. 



Sir, — On September 1 of this year I found the well-known tower 

 of Sidestrand old Church, near Cromer, now on the very edge of the 

 cliff : a rabbit could not pass between. It had begun to crack, and 

 its fall may come at any time. On April 27, 1905, I made a rough 

 map of churchyard, tower, and cliff-edge; and noted the distance 

 between tower and cliff-edge as then 7 feet. I record this as a contri- 

 bution towards estimates of cliff- waste on this coast. 



In the Geological Magazine, 1895, pp. 229, 230, are calculations 

 of rate of inland retreat for the sand-dunes at Eccles, 12 miles south- 

 east. The calculations give a retreat of somewhere about 130 feet in 

 seventy-seven years.

HUMAN PALEONTOLOGY IN ENGLAND. 



Sir, — The current number of L^ Anthropologic (January- April, 

 1915), I notice, contains a paper by M. Boule entitled " La 

 paleontologie humaine en Angleterre ", which is the most extra- 

 ordinarily biassed statement it has ever been my ill-fortune to read.
