A Bibliography of the Tunicata, 1469-1910.— By John 

 Hopkinson, F.L.S. 288 pages. 9-in.X 5i-in. 



(Dulau & Co. Price 15/- net.) 



When Mr. John Hopkinson was preparing for publication 

 Alder & Hancock's " British Tunicata " he compiled a 

 bibliography for his own use, bringing matters up to the 

 year 1870, and liter, after consultation with Canon Norman, 

 he decided to extend it to the year 1910. This has now been 

 printed and forms one of the volumes published by the 

 Kay Society for the year 1912. The care with which Mr. 

 Hopkinson works is well known, and though he has been 

 assailed with various difficulties he has produced a volume 

 which will be of very great assistance to students of the 

 Tunicata, while he has made up for any little deficiencies 

 due to the printing of the work in two parts by appending 

 an addenda of twenty-five pages. w ., .,, 



The British Parasitic Copepoda. — By Thomas Scott, 



LL.D., F.R.S., and Andrew Scott, A.L.S. Volume I. 



Copepoda Parasitic on Fishes. 256 pages. 2 plates. 



9-in.X 5j-in. 



(Dulau & Co. Price 15/- net.) 

 This, the second of the volumes published by the Kay 

 Society to subscribers for the year 1912, consists of the text 

 of Messrs. Scott's work, with two plates. The bulk of the 

 plates will appear as a volume for 1913. The Kay Society 

 published in the years 1878-1880 a monograph of the British 

 Free and Semi-parasitic Copepoda, by Dr. G. S. Brady, and 

 from this those forms which were truly parasitic on fish were 

 expressly omitted. Dr. Brady suggested that they should be 

 dealt with in a separate volume, and Messrs. Scott have now 

 produced it. With very few exceptions recent specimens 

 have been examined and carefully dissected. The result is a 

 series of very careful descriptions, to which are added details 



of the habitats. „. ,, ,,,

NOTICES. 



THE KOYAL INSTITUTION.— A General Meeting of the 

 members of the Royal Institution was held on the afternoon 

 of June 2nd, the Duke of Northumberland, President, in the 

 chair. Mr. L. K. Guthrie, Mr. G. W. Heath, and Mr. K. 

 Malcolm, were elected members. The Chairman reported the 

 death of the Right Hon. Lord Avebury, a member of the 

 Institution for sixty-four years, and a resolution of condolence 

 was passed. 



SECOND-HAND PHYSICAL APPARATUS.— Messrs. 

 Newton & Company announce that owing to the great develop- 

 ment of their optical business they can find neither time nor 

 space for their Philosophical and Physical Apparatus 

 Department, and are therefore disposing of the whole of their 

 stock at a low valuation. A catalogue has been issued, 

 including demonstration apparatus in Electricity, Chemistry, 

 Pneumatics, Sound, and so on. 



ADDITIONS TO THE -ZOOLOGICAL SOCIETY'S 

 MENAGERIE.— The number of additions to the Zoological 

 Society's menagerie during the month of May was two 

 hundred and sixty-eight, and among those which are new to 

 the collection are two White-bearded Gnus (Connochaetes 

 albojubatus) received in exchange, two Naked-tailed Mice 

 (Uromys bruijnii) from Dutch New Guiana, presented by 

 Mr. A. F. R. Wollaston, and a Chestnut-faced Barn Owl 

 (Strix castanops) from Tasmania, which was purchased. 



THE EAST COAST. — The east coast affords an oppor- 

 tunity for good work in Natural History and Archaeology, and 

 we recommend to those who are thinking of spending their 

 holidays there, a little book entitled " On the East Coast," by 

 Percy Lindley, fully illustrated in half-tone and colour, which 

 has just been issued by the Great Eastern Railway Company, 

 and can be obtained gratis from the Superintendent of the 

 Line. 



BOOKS ON BIRDS.— Ornithologists will be interested in a 

 catalogue which Messrs. John Wheldon & Company have just 

 issued containing more than fifteen hundred titles. Besides 

 general works dealing with the subject under geographical 

 headings, sections are devoted to migration, to game and 

 domestic birds, as well as to bird protection. No less than 

 eighteen editions of " The Natural History of Selborne," by 

 Gilbert White, are included under " Selborniana," with other 

 works relating to the great field naturalist. 



A NEW CAMERA.— We have received an intimation that 

 in anticipation of the holiday season, to which the taking of 

 photographs adds a great charm, the Optical Works of 

 Messrs. Goerz are introducing a new " Tenax " camera. The 

 working of this is simplicity itself, and it has an accurately 

 graded shutter as well as all the movements required. Added 



to this it is fitted with one of the world-famous Goerz lenses, 

 and the scientific worker who wants a camera will feel quite 

 happy in taking advantage of what has been done for his lay 

 brethren. 



ENGLISH MICROSCOPES.— We have pleasure in calling 

 attention to Messrs. James Swift & Sons' catalogue of 

 Microscopes and Accessories. In runs into seventy pages 

 and contains figures and descriptions of the more important 

 of the well-known microscopes which this firm produces. 

 There are some pieces of apparatus of particular use in 

 certain cases that may be mentioned, such as the Stevenson 

 Binocular Microscope for delicate dissection; the simple cone 

 camera for attachment to the draw tube of the microscope, 

 and the stereoscopic photomicrographic attachment designed 

 by Professor Herbert Jackson, which gives perfect stereoscopic 

 photographs of suitable subjects under the microscope. 



MACMILLAN'S NEW BOOKS.— The catalogue of new 

 books which has just been issued by Messrs. Macmillan contains 

 among the notes, some details of the life of Miss Octavia Hill, 

 and in the classified list of books recently issued we notice 

 several on Archaeology and Agriculture. Mayo's " Diseases of 

 Animals " has been increased in price from 6s. 6d. net to 

 8s. 6d. net, and "Franklin's Electric Lightning " from 10s. 6d. 

 to 12s. 6d. Volume XC of Nature, September, 1912-February, 

 1913, is now ready, price 15s. net. 



NESTING BOXES. — The great benefits which many birds 

 confer on the agriculturist and the forester have long been 

 appreciated in foreign countries, and recently it was 

 pointed out in the press how the Thirlmere plantations had 

 been saved from the attacks of the larch saw-fly owing to the 

 provision of nesting sites by the Manchester Corporation. In 

 this connection it is interesting to chronicle that the Royal 

 Agricultural Society has specially invited the Selborne Society 

 to send a representative series of its very successful nesting 

 boxes to the Forestry Exhibition, which will be held in con- 

 nection with the Royal Show at Bristol from July 1st to the 

 5th. 



THE EMU. — Messrs. Witherby & Co. have been 

 appointed European Agents for The Emu, the organ of the 

 Royal Australasian Ornithologists' Union, and copies of that 

 publication can now be obtained at 326, High Holborn. 



THE NATIONAL PHYSICAL LABORATORY.— The 

 Annual Meeting of the General Board of the National 

 Physical Laboratory was held recently at the rooms of the 

 Royal Society, when the report and accounts for the year 

 1912 and the statement of work for 1913 were presented and 

 approved for transmission to the President and Council of the 

 Royal Society.
