HARDWICKE'S SCIENCE-GOSSIP. 



L. Bennett. — Vou can obtain no better popular book than 

 Dr. Cooke's "Microscopical Fungi." The work on "Fungi," 

 by the same author (in conjunction with the Rev. ^I. J. 

 Berkeley), which forms one of the volumes of the " Interna- 

 tional Scientific Librar}'," ought to be read. Dr. Cooke's best 

 and most exhaustive work is his " Handbook of British Fungi," 

 in two volumes, published by Messrs. Macmillan, at (we be- 

 lieve) one guinea. It contains descriptions of all our fungi, 

 microscopic and otherwise. 



C. KiNGSFOKD. — The Infusoria are single-celled animalcules, 

 and the substance of their bodies is pure protoplasm, which is 

 composed of carbon, oxygen, hydrogen, and nitrogen, with 

 constant traces of sulphur and phosphorus. Living protoplasm, 

 however, is always in a state of change, or chemical instability, 

 owing to new food being constantly assimilated, and other parts 

 being wasted or used up. 



L. B. — The fragments of dried herbs you sent us were covered 

 \\ith the spores of a species of white rust (Cystopus). 



T. W. AND Others. — The "Oologist" is a monthly journal 

 devoted to the study of birds and their eggs, and is published 

 at Rockville, Connecticut, U.S.A. 



T. L.A.MBEkT (Edinburgh).' — Will you kindly send us your full 

 address ? 



W. White.- We shall be very glad to accept one of j'our 

 slides. 



F. A. L. (Ceylon). — Two of your articles are to hand, and 

 shall appear as soon as possible. We have recently received 

 such a large number of excellent articles on such a variety of 

 popular and attractive subjects, as to make us wish Science- 

 Gossip were double the size, so that we might submit them the 

 sooner to our readers. 



C. R. L.— You will find full descriptions of the Derbyshire 

 "Toadstone" in the Rev. J. Mello's " Geology of Derbyshire," 

 (published by Bemrose, Derby). See also Rutley's " Study 

 of Rocks," 4J. (sd., published by Longmans & Co. 



G. A. L. — Your fossils are as follows : the fibrous-structured 

 fragments of shells are remains of Inoayaimis Cuvieri, very 

 common in the chalk. The other portion is probably a frag- 

 ment of fish-bone. You had better consult Dr. Mantell's 

 books ("INIedals of Creation," &c.) for popular descriptions of 

 chalk fossils and how to prepare them. 



E. L.— We were obliged to clo^e our correspondence earlier 

 than usual this month, but exchanges, &c. stand over till our 

 next number.
