134 NATURAL SCIENCE [August 



Our Naturalists 



Mr L. Upcott Gill, 170 Strand, has kindly sent us " The Naturalist's 

 Directory," 1897; price Is. This, the third edition, will undoubtedly 

 be useful to us, for it contains a large number of names that are not 

 to be found in the ordinary lists of learned societies or in the invalu- 

 able " Zoologisches Adress-1 >uch " of Friedlander. We presume the 

 majority of those included in the above-mentioned works are here 

 omitted of set purpose ; there would be no difficulty in comprising 

 them. At the same time, some hint might have been given as to the 

 principles on which the selection was made. It is pleasing to find 

 that there are so many people claiming to be naturalists in the British 

 Isles. As for the foreign and colonial lists, their similar vagaries are 

 perhaps due to the fact that they are avowedly restricted to persons 

 desiring to correspond or exchange specimens with collectors and 

 students in this country. The extension of these lists, no difficult 

 task, would be of much use. The book also contains a trade-directory, 

 a list of societies, field-clubs, and museums in the British Isles, a list 

 of the principal natural history works published during 1896 in the 

 British Isles, and a somewhat erratically selected but useful list of 

 natural science magazines, in which, if we may judge from our own 

 case, the information is not always so correct as it might be. 



Botanical Bibliography 



The Cambridge Botanical Supply Co. are distributing samples of 

 their card catalogue of current literature relating to American botany. 

 Items are arranged according to authors' names, but an edition of 

 subjects is also in preparation. The matter is prepared by a board of 

 editors, which includes the leading botanists of Columbia College, the 

 National Herbarium, and other institutions, and is published under 

 the direction of a committee of the American Association for the 

 Advancement of Science. 



The cards used are of heavy linen ledger paper made to order for 

 this purpose. They are cut with extreme accuracy by an expensive 

 machine. The size is 50 by 125 mm. The number of cards issued in 

 1891 averaged 49 per month ; for 1895 the average was over 60, and 

 the total number of cards to April 1897, 2319. Subscriptions ($5, paid 

 in advance) may be sent to Wm. Wesley & Son, 28 Essex Street, 

 Strand, London. 



We commend this useful enterprise to the notice of the British 

 Association for the Advancement of Science. 



Westmorelandshire's Field Geology forms the subject of a paper 

 by Mr H. G. Foster- Bar! lam, which was read before the Burneside 

 Mutual Improvement Society on February 11, 1897. The paper, 

 which is illustrated by sketch-maps and sections, is published by 

 B. Atkinson, Stramongate, Kendal, at Is., post free, and gives a general 

 account of the interesting district. 



Scraps from Serials 



The ever interesting Scottish Geographical Magazine gives two 

 lively articles in its July number. Sir Henry Tyler writes on the
