NOTICES TO CORRESPONDENTS. 



j. p.— Bentall's Botanical Paper is generally most approved. 

 It may be had of Mr. E. Newman, Devonshire Street, Bish- 

 opsgate, London. 



J. S. W. D. — There are Natterjack Toads in Ireland, but 

 reptiles are certainly rare enough to warrant the old story of 

 St. Patrick. Why it is so we do not pretend to know, and 

 will not guess. 



W. L. W. E.—Hypnum tenellum.—B, B. 



3. C. D. — No. 2. Bryum pseudotriquetrum, young. — R. B. 



A. A.— We will keep the subject in mind. Within a month 

 we shall be able to make some inquiry. 



H. T. W.— The shells are — 1. Helix uspersa. 2. H. nemo- 

 ralis. 3. H. hortensis. 4. H. virgata. 5. H. rufescens. 6. 

 S. Cantiana. — E. A. S. 



" Kingfishers," with no name or address, found its way 

 into the paper-basket— of course. 



E. M. H.— It is of no use noticing them now that they are 

 gone. 



J. C. G. — You put no address on your notice for Exchange 

 column ; hence it would be useless to insert it. 



J. T. N.— An old trick, often recorded. 



E. E. J.— Curious, very ! Was it a young sphinx ? 



R. H. — M. Nachet's address is No. 17, Rue Ste. Severin, 

 Paris. We are not aware that he has any London agents. 

 His immersion objectives might be obtained through a Lon- 

 don optician. 



W. D. T. — Poor cats', why should they be worried to 

 death? We think that "Gossip" has done enough to 

 them. 



F. T. — Ineligible for insertion in " Exchanges," not being 

 " Objects of Natural History." 



E. A. W. — Your query being of individual interest only, 

 you had better inquire of Mr. Pettitt, of Dover. 



R. D. K.— At present we know nothing more than the 

 paragraph quoted, nor do we know of a London agent for 

 Foreign objectives. 



F. D.— One at a time. 



A. B. — 1. Sinapis (Diplota.ris, D. C.) tenuifolia, R. Br. 2. 

 Brassica (Sinnpis, D. C.) juncea, L. 3. Neslia paniculata, 

 Desv. Further particulars regarding the abundance and 

 permanence of the two last would be of interest.— B. 



C. A. C. — Selaginella Braunii, Baker. — J. G. B. 



W. H. S.— Probably Cystopteris dentata.—J. G. B.
