Zoological Address-book. — A second edition of the Zoologisches 

 Adressbuch has just been issued for the German Zoological Society by 

 Friedlaender and Sohn for seventeen marks bound. It is a bulky 

 volume of 1110 pages, and from the careful manner in which people 

 in this country are circularized should be found of great service. 

 Universities, Academies, and Societies are included, and the total 

 number of names listed reaches the astonishing total of 17,800, all 

 forming one index at the end. The book will appeal to geologists as 

 well as zoologists, for palaeontologists are included. Errors can be 

 found, but what book of this nature is free from them ? and such errors 

 are frequently due to the indolence of those receiving the circular in 

 not troubling to return it to the publishers. 



Antkrapaljemon Grossabti,S\-lter, 1 86 1 , Rochdale : A Correction. 

 — In the August Number of the Geological Magazine, pp. 361-6, 

 1911, I published an account of the genus Anthrapalcemon, and 

 figured a very beautiful carapace from Sparth, Rochdale, which 

 I stated was obtained by Mr. Fred Holt in 1907. In this I find 

 I was in error, as the specimen in question was found by Mr. H. 

 Howard, of Rochdale, but was sent to me by Mr. Holt. This 

 applies also to the fragmentary specimen of a scorpion, Eobuthus holti, 

 Pocock (Mon. Pal. Soc, 1910, p. 14, pi. ii, fig. 2), which I had 

 placed in Mr. Pocock's hands to describe. I regret that I overlooked 

 the fact that both the above specimens were obtained by Mr. Harold 

 Howard. Mr. Howard also mentions that in Mr. Baldwin's article 

 on some " Fossil Myriopods from Rochdale " the writer refers to 

 one JEuphoberia (Geol. Mag., p. 78, February, 1911) as having been 

 found by Mr. F. Howard : this should read Mr. H. Howard.— H. W. 



Our Future Coal Supply. — Mr. McKenna (Home Secretary) on 

 October 30 issued the following statement : "I have seen a report of 

 the address delivered by the President of the British Association, but 

 I observe that the President's forecast of the probable duration of the 

 coal supplies of the country does not take into consideration certain 

 factors which have an important bearing on the question. In the 

 first place, the President's estimate took no account of the large 

 amount of coal in fields unproved at the time of the inquiry of the 

 Royal Commission, nor of the amount of coal lying below the depth 

 of 4,000 feet, which the Commission took to be the present limit of 

 workable coal, but which it may be found possible hereafter to exceed. 

 These two sources the Commission estimated at over 39,000 and 5,000 

 million tons respectively, or together nearly half as much as the 

 amount of coal estimated to exist in the proved coal-fields. In the 

 second place, the President's estimate was based on the assumption 

 that the output of coal would continue, at any rate for some time, to 

 increase at the same rate as in the past. The Commission, on the 

 other hand, considered that at a time not far distant the rate of 

 increase of output would become slower, to be followed by a period of 

 stationary output, and then a gradual decline. No recommendation
