Queries. — Having been inundated vatli questions, 

 wc are compelled to announce that we cannot 

 undertake to answ'cr those of which the querist 

 might satisfy himself by an appeal to any ele- 

 mentary book on the subject. We are always 

 prepared to accept queries of a critical nature, 

 and to publish the replies, provided some of our 

 readers, beside the querist, are likely to take an 

 interest in them. 



Cakboxile. — Por information respecting this E. G. 

 must apply to the inventors, Messrs. Glover and 

 Sons, Ranelagh-road, Pimlico, S.W. 



M. X. — We are not aware that any of the lectures 

 you name have been published. 



AsTECosromuJi PIofemanni. — Having obtained 

 other specimens, and distributed them, we hope 

 that now every one who was previously disap- 

 pointed has been supplied. 



T. O. B. — We fear that, _ practically, we could not 

 carry out your suggestion in a periodical. 



J. W. (Amlwch). — Procure the "Manual of Struc- 

 tural Botany," Hardwieke, Is. 6d. ; and Oliver 

 and Henslow's " Botany," about 5s. 



P. W. II. — It is a dung beetle {GeotrwpespuncticoUis, 

 Steph.). This will suggest the reason for your 

 being unsuccessfid. 



E.. S. B.— It is quite a matter of taste. Look at the 

 insects in the British Museum. 



V. P. — Keep camphor, or some turpentine on a 

 sponge, with your skins. 



H. G. — West wood's " Introduction to Entomology," 

 2 vols., about 14s., and Stephen's "?iranual of 

 Beetles," 7s. ; second-hand, at Mr. AYheldon's, 

 58, Great Queen-street, London. 



P. W. — Is referred to page 2i, whence he will learn 

 that lists and tables are inadmissible. 



C. A. J.— ;The excrescences arc produced by a dip- 

 terous insect ; no one would venture to say what 

 species without seeing it. 



T. C. — (1.) Some emerge, others become victims, 

 the majority hybernate. (2.) Look for the two 

 crowns. (3.) Yes. (4.) Doubtless, the snails. 



A. Z. — Queries which, with their replies, are only 

 likely to interest the querist, can only be answered 

 briefly here. 



CuiiATOB. — Asphalte is the best cement for ordinary 

 cells, and is easily manipulated with the aid of 

 Shadl)olt's whirling tabic. The thin glass cover 

 is easily secured wilh the same cement. — W. M. B. 



J. P. C.-Consult Dr. Ilassall's "Pood and its 

 Adulterations." — The brown scale frequently seen 

 on the rinds of oranges is the shield of a coccus 

 or scale insect. An interesting paper, with illus- 

 trations, on this subject, by Mr. Bichard Beck, 

 will be found in the Transactions of the Micro- 

 scopic Society of London, vol. ix., new scries, 

 page 47.— 7r. M. B.

 names of your mosses shall be sent. We cannot 

 afford space for so long a series. 



W. S. K. — Tlie cost of a camera lucida is from one to 

 two guineas : a very good substitute may be had 

 of some opticians for five shillings ; of a Cod- 

 dington lens from five shillings. 



W. M. P. P.— Possils and minerals may be purchased 

 at any of the following slioi^s in London ; we can 

 sav nothing of the relative prices: — Temiant,
