HARDWICKE'S SCIENCE-GOSSIP. 



263 



Hamilton, in the October Number of Science- 

 Gossip, having so particularly noted the cuckoo's 

 song, will be able to state if it is the male or female 

 bird, or both, that gives the pleasing love-call. I 

 see Morris does not speak positively to the fact. — 

 W. H. T. 



A Design of the Daisies. — I do not know 

 whether it be correct to say purple-eyed, orange-eyed, 

 crimson-eyed or blood-bedropped daisies. Those 

 who consider a daisy as a mere time-piece akin to a 

 watch, would lead us to suppose that these spots 

 were a kind of rouge daubed on to the disk for the 

 sake of ornament, whereas, this natural dye is like 

 the blush on the cheek, a secretion, and shows that 

 modest flower is proud of its lineage. One spring 

 day I strolled out from Bedford towards Sandy, and 

 on approaching the latter town by the Cardington 

 Road, I observed these sentimental daisies in plenty 

 at the way-side, and saw at a glance that they were 

 looking up in their environment, their growth being 

 pre-eminently rank, coarse, and luxuriant ; I fancy 

 they will soon be in excess of the silver star of the old 

 regime at Sandy. — A. H. Swinton, 



NOTICES TO CORRESPONDENTS. 



To CORRKSPONDKNTS AND EXCHANGERS. — As We HOW 



publish SciENCK-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 oi omt 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. 



Dorsetshire Resident. — i. See chapter entitled, "The 

 Story of a Piece of Chalk," in Taylor's "Geological Stories" 

 (W. H. Allen & Co.). 2. You will find the numbers of foramini- 

 fera in chalk, and also instructions how to procure them, in 

 "Our Common British Fossils" (Chatto & Windus). 3. Will 

 be found answered by No. i query. The "little creature" you 

 sent is Gcophilus longicornis. 



F. J. George. — Many thanks for your interesting specimens 

 of Merairialis autiannalis. 



H. Roberts inquires what natural history societies exist 

 near Maida Vale, St. John's, or Kilburn. Perhaps some 

 reader will inform us. 



J. T. B.WLEE. — Get Page's " Economic Geology," published 

 by Blackwood. You will therein find much about clays ; also 

 in Professor Ansted's books. 



W. T. Calm.\n. — It is impossible to make out the species of 

 rotifer from the slight and rough sketch sent us. It does not 

 look like a rotifer at all. 



T. U. Woodward. — You will be able to procure micro-slides 

 of horse-tails from Mr. H. P. Aylward, 164 Oxford Street, 

 Manchester. 



S. L. Fletcher. — The occurrence of "double apples" is not 

 unusual. You will find an illustration and description of them, 

 as well as an explanation of their origin, in Dr. Masters's 

 "Vegetable Teratology." 



W. F. Jones. — The force required to separate the Magde- 

 burgh hemisphere could be known by calculating the number 

 of square inches of area, and multiplying by fifteen, which 

 would give the result in pounds. 



C. C. Wilson. — See answer to query about double apples. 

 The " red fungus " reached us in too high a state of decomposi- 

 tion to identify it. 



F. T. M. — Send us some more specimens, same as last. 



R. G. M. — Your specimens are i and 2 bryozoan zoophytes. 

 I is Membraniporapilosa, and 2, Membranipora 7nembranacfa. 

 The "hooked seed" are the fruits of Medicago minima.
