NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Scik.vck-Gossip at least a week earlier than hereto- 

 fore, we cannot possibly insert in the following number any 

 communications which reach us later than the 8th of each 

 month. ^__^_ 



W. Tarrow. — The specimen found in copse was the 

 "Wood Forget-me-not" (Myosotis sytvaticum). 



A. M. C. — Get Gould's " Mammals of Australia," published, 

 we believe, by Van Voorst. You may see it at the Library of 

 the British Museum. 



A. L. P. H.— The shells in the quill, called "Rice Shells," 

 are Oliva oryza ; the white ones are a species of Marginella. 



C. W. A. — Your Palmipes with six rays is, undoubtedly, a 

 monstrosity of P. membranaceux. Pinnotheres pisum differs 

 from P. veterum in that the front of the male of the former 

 projects. The female pisum has the abdomen broader than 

 long', whilst that of veterum is longer than broad. In the 

 male of veterum the carapace is subquadrate, rounded, and 

 the front slightly etnarginate. The carapace of the female 

 pisum is uniformly rounded at the anterior margin. 



J. W. Mee. — The best way to preserve your wood will be 

 to creosote it. 



Cephas. — Wood's " Insects Abroad " is published at 16s. 

 by Longmans & Co. " Out and About " is by Hain Friswell, 

 and published by Groombridge at 3s. 6d. Huxley's " Lessons 

 in Elementary Physiology" is published by Macmillan at 

 4s. 6d. We should think you could obtain a frog's skeleton 

 from any natural history dealer in London. 



Dubins. — The objects you mention embedded in the peel of 

 orange are the pupa-cases of Ceratites citriperda. 



H. W. Hollenburgh. — Copaline or Copalite, the fossil 

 resin found in the London clay, might be obtained, we should 

 think, from Tennant's shop, 149, Strand, London. 



E. Halse. — Article will appear shortly. 



F. T. P. — We do not know of anything that will prevent 

 mice eating crocus-bulbs. Perhaps some of our readers may, 

 and will communicate with us concerning it. 



A. S. — Melicerta signifies the " Honey Floscularia." The 

 book you name has not much value as a scientific work. 

 You had better see Carpenter's " Animal Physiology," or 

 Rhymer Jones's " General Structure of theAnimal Kingdom." 



T. Rogers.— Your specimen is a form of Sphagnum acuti- 

 fiilium. 



3. Maxwell. — Your mosses are as follows :— 1. Sphagnum 

 cymbifulium ; 2. Dicranella lieteromalla ; 3. Trichocolea 

 tnmentella; 4. Thamnium alopecurum ; 5. Pogonatum aloi- 

 des ; 6. Mnium punetatum. — R. B. 



E. Edwards.— Many thanks for the early Daffodils, which 

 came safely and welcomely to hand. 



Errata. — By some means, at the last moment of going to 

 press with the April number, the blocks illustrating Mr. 

 Bridgman's articie on "Ringing Slides" were transposed. 

 Fig. 34 ought to read " Cell and slide seen edgeways, show- 

 ing the shape of foundation"; fig. 35, "34 in section''; 

 fig. 36, " Section of cell complete" ; and fig. 37, " Section 

 of cell with too large a cover, showing the weakness of its 

 attachment." 



Editorial. — Absence on the Continent has prevented the 

 Editor inserting many of the later communications sent to 

 him this month. Indeed, the amount of literary correspond- 

 ence he now receives is such as to suggest the necessity of 

 permanently enlarging Scienck-Gossip to an additional one- 

 half its present size, with additional illustrations, &c. This 

 would, of course, oblige the Publisher to issue it at 6d. 

 instead of 4d. per month, as hitherto. Before committing 

 ourselves to so important a change, we should be glad of the 

 opinion of our numerous and oldest contributors and sub- 

 scribers for and against.
