HARDWICKE'S SCIENCE-GOSSIP. 



T. S. King. — We should be very glad indeed to possess a 

 specimen of the insect for microscopical purposes. 



C. F. W. T. Williams. — Both your papers on micro-fungi 

 are in hand. 



V. G. — " Hay fever" is caused by the abundant pollen thrown 

 nto the atmosphere whilst various grasses are in. flower. The 

 immediate cause of the catarrh is the possession of a chemical 

 principle called Coumarin by the pollen grains. The idea of 

 animalcula causing hay fever is nonsense. 



F. Johnson. ^You should consult the Transactions of the 

 Epping Forest Naturalists' Field Club for matters relating to 

 the natural history of the forest. Write to the Hon. Sec, 

 Mr. Cole. 



F. J. George.— Accept our thanks for the very curious speci- 

 men of 5-petalled stellate strawberry. 



J. H. Payne.— We have examined the so-called "growth" 

 in a solution of aluminous salt under the microscope with 

 ^inch power, but consider it as perhaps only a flocculent pre- 

 cipitation of organic matter. 



L. L.— Get Dr. Gunther's " Introduction to the Study of 



Fishes." , ^ r, 



W. P. Henderson. — We can cordially recommend the fol- 

 lowing books on the subjects you mention : " Origin and 

 Metamorphoses of Insects," by Sir John Lubbock, Bart, (one 

 of the "Nature" series of vols.), published by Macmillan ; 

 "Transformation of Insects," by Professor Martin Duncan 

 (Cassell's) ; " Guide to the Study of Insects," by Professor 



Packard. , . , . t^ 



\V. H.— Vou will find all that can be said concerning Drosera 



in Darwin's " Insectivorous Plants " (London : John Murray). 

 M. N. N. S. C. — The antennae of insects are the seat of a 



special sense, of which we can scarce form any conception. By 



them they communicate with one another, they recognise objects, 



and seem to distinguish with their aid, their friends from their 



foes— by instinct or " hereditary knowledge." 



R. B. and B. W.— Your queries will be answered m next 



month's issue.
