CORRESPONDENCE. 



J. Ballantyne (Rothesay). — There can be no doubt that 

 you are correct. The error was due to reliance on memory 

 instead of a reference to typical specimens and careful 

 diagnosis. Thanks for your letter. 



J. S. Dismorr (Gresham House). — We regret that we are 

 unable to answer your query, which should have been 

 addressed to one of the trade journals or to a consulting 

 chemist. It lies outside our territory. 



H. N. Lowrv (Aldershot). — We take your Luzv.la to be the 

 L. campestris, Willd., var. erecta of Hooker's " Student's 

 Flora." The Juncus we make out to be J. bufonius, L. 

 Owing to the smashing of the tin bv the postal stampers, the 

 Mentha reached us in a very shrivelled and broken condition, 

 which made identification difficult, but it appears to be .V. 

 aquatica, L. 



J. W. Champlin (Hartlepool). — It is difficult to recommend 

 a beginner a good modern book on so great a subject as 

 general zoology at the price you name. We do not think 

 you can do better than get Rymer Jones' " Animal Creation : 

 A Popular Introduction to Zoology," published by F. Warne 

 and Co., price 5s. You will find a capital account of bats in 

 the "Royal Natural History," part; 3 and 4 (F. Warne 

 and Co.). 



W. J. Mountford (Darlington). — (1) Your No. 1 has been 

 so thoroughly divested of all character by long rubbing by 

 sand and waves that it would be impossible to identify it. 

 No. 2 is Cerithium rcticulatv.m ; No. 3 is Trochus cinerarius— 

 both very abundant species. (2) We do not know one we 

 could recommend ; J. G. Jeffreys' is the best, but it is expen- 

 sive and in five volumes. You could probably see it in your 

 free library ; the title is " British Conchology." 



J. Lewton Brain (Swanton Morley). — (1) The Alga, 'con- 

 cerning which you wrote on September 15th. is no doubt 

 some species of Oscillaria. The most recent work is Dr. M. 

 C. Cooke's " Introduction to Freshwater Algae." It contains 

 an enumeration of all the British species and illustrations of 

 all the genera. It is one of the " International Scientific 

 Series." published by Kegan Paul, Trench and Co., price 5s, 

 (2) MS. to hand; we hope to use it in our next issue.
