HARDWICKE'S SCIENCE-GOSSIP. 



C. O. Lowe. — We shall be very pleased to have your sketch 

 of a revolving table. 



J. P. Page. — You would get either of the books you mention 

 of Mr. W. Collins, scientific bookseller, 157 Great Portland 

 Street, London, W. 



R. F. Z. — The Religious Tract Society have just published 

 a pleasant little book, called "Ants and their Ways." 



T. J. Wilkes. — No. 4 is the dogwood {Cornus sangui- 

 neus) ; No. 8, Orchis metadata ; No. 10, fig-wort (Scropltu- 

 laria nodosa) ; No. 16, the flowering rush [Butomus umbel- 

 latus); No. 18, Polygonum amphibium. The rest were rightly 

 named. 



T. S. T. — The recipe for a good cement for joining together 

 rockwork, as given in Taylor's "Aquarium," is the best we 

 know of. Marine glue also forms a good cement ; gutta-percha 

 is untrustworthy. 



A. J. S. (Kentish Town). — It is a specimen of pear [Pyrus 

 torminalis), but the fruit is not so pleasant as the jargonelle 

 pear. 



S. A. S. (Belfast). — You will find the species alluded to in 

 Berkeley's " Cryptogamic Botany," as a puzzling one, in the 

 fungi. 



F. W. C. (Bedford). — It is the reindeer moss, so called, 

 though it is a lichen. 



J. S. (Bolton). — The firm you mention are still to be found 

 in Paternoster Row. No. 1, Tortula inuralis ; 2, Funaria 

 hygrometica ; 3, Bryum, but not in fruit. 



D. D. (Thornhill, N.B.). — No. 1, Carex sylvatka; 2, C. 

 riparia. The Salices are such a puzzling species that, unless 

 they are carefully dried with male and female catkins, it is 

 unwise to name them. However, No. 4 is ^. cinerca.
