spectabilis," "Delightful spectacles," " Cotoneaster," 

 "Cat -in -Easter," "Nasturtium," "Extortion," 

 "Anemone," "Any money," " Tropeolum specio- 

 sum" Something special from the Tro-picks. — 

 S. A. B. 



Influenza. — The influenza, which has been so 

 prevalent, is called about here, "Flying Nancy." 

 "Kecks" a local name for "Water Hemlock" and 

 plants of that order. Queen's Co. — Rev. S. A. Brenan, 

 Cushcndun, co. Antrim. 



Insect Parasite on Cattleya. — Can any 

 reader inform me, through the medium of Science- 

 Gossip, the scientific name of the insect which 

 affects certain orchids (Cattleyas). I have been told 

 that it is not yet decided upon as to what it is, as it 

 has only of late years been imported with the pseudo- 

 bulbs to this country, but I should think it is known 

 to entomologists. — Parsons. 



Hypnotised Water. — Will you permit me to 

 state, in reply to a correspondent in Natural History 

 Notes, that water is not always in motion. If your 

 correspondent will take a beaker, fill it with distilled 

 water, turn it upside down till all that can be is 

 poured out, then place it upright on a table for a few 

 minutes, he will then find at the bottom of the 

 vessel a minim rest of water. — IV. A. Ward. 



The Kingfisher. — I am glad to see that this 

 bird is getting less scarce in the neighbourhood of 

 Cambridge than it was a year or two ago. At one 

 time these beautiful birds might have been frequently 

 seen about the watercourses near the University town, 

 but such a relentless war was waged against them 

 that they were apparently exterminated. The 

 " Wild Birds' Preservation Act," however, seems to 

 have operated in their favour, and they are once more 

 becoming, at least occasionally, visible. — Albert H. 

 Wallis. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip earlier than formerly, we cannot un- 

 dertake to insert in the following number any communications 

 which reach us later than the 8th of the previous month. 



To Anonymous Querists. — We must adhere to our rule of 

 not noticing queries which do not bear the writers' names. 



To Dealers and Others. — We are always glad to treat 

 dealers in natural history objects on the same fair and general 

 ground as amateurs, in so far as the " exchanges " offered are fair 

 exchanges. But it is evident that, when their offers are simply 

 Disguised Advertisements, for the purpose of evading the cost 

 of advertising, an advantage is taken of our gratuitous insertion 

 of "exchanges," which cannot be tolerated. 



We request that all exchanges may be signed with name (or 

 initials) and full address at the end. 



Special Note. — There is a tendency on the part of some 

 exchangers to send more than one per month. We only allow 

 this in the case of writers of papers. 



W. H. Cooke. — The " Northern Microscopist " is, we 

 believe, no longer in existence. "The Microscope" is an 

 American publication, published at 145 N Greene Street, 

 Trenton, New Jersey, U.S.A. It can also be obtained of 

 W. P. Collins, 157 Great Portland Street, London, W., price 

 $s. per annum. 



Conchologist. — The bleached white shell is Purpura 

 lapillus ; the land shell is Helix virgata. 



C. J. Danks.— Write to Mr. Jamrach, St. George's-in-the- 

 East, London. He is the greatest dealer in living animals. 

 Montagu Brown's " Manual of Taxidermy" is the best. 



H. Durrant. — Consult a copy of Taylor's "Aquarium: Its 

 Inhabitants, Management, and Structure," for what informa- 

 tion you require. You will find a copy at most libraries, or 

 may procure it of Messrs. Allen, Waterloo Place, London. 



H. C. T. Lancdon.— Write to Mr. W. P. Collins, 157 Great 

 Portland Street, W., or Mr. W. Wesley, Essex Street, Strand, 

 for a copy of " Lowne on the Blowfly." The last copy we 

 saw was offered for 10s. 6d. 



Dr. Macindoe. — No. 1, fungus parasitic on stem of cock's- 

 foot-grass, is Epkhloe lyphina ; No. 2 is a Clavaria, possibly 

 aurea ; No. 3 is Xylaria kypoxylon, the so-called " candle- 

 snuff" fungus. 



J. H. Cooke (Malta).— Please forward the article, with 

 illustrations. 



T. Ili.ingworth. — We shall be pleased to receive your 

 paper on the Coloration of Birds' Eggs. 



C. J. Watkins. — We have been frequently asked to publish 

 another General Index to the past vols, of Science-Gossip, 

 but as yet nothing has been finally decided upon. 



John Cookson.— We are not acquainted with the "Natu- 

 ralist's Gazette." Perhaps some correspondent is, and could 

 inform us of the publisher.
