We have already noticed in these columns previous 

 numbers of the Encydopedie Scieniifique, of which these 

 present volumes form a recent addition, and further re- 

 marks on the general excellence of the plaa adopted 

 would be unnecessary. The detailed but concise descrip- 

 tions of the individual arts and sciences, with separate 

 volumes, each devoted to some particular speciality or 

 division of the whole, and each complete in itself, is au 

 undertaking suiSciently vast to make a doubt as to its 

 success perfectlj' natural. But under the directorship of 

 M. Leaute, Membre de I'lnstitute, and of M. Masson, 

 editor, this success has certainly been attained, and we 

 are presented with a series of works each superior in its 

 particular field, and of value to a specialist as well as to 

 the general reader. The first volume, treating of the 

 tanning industry, naturally appeals most strongly to the 

 manufacturer and to the chemist. The discussion con- 

 sists, in brief, of the study of the crude materials and the 

 chemical products which are introduced, of the theory of 

 the successive operations of manufacture and their prac- 

 tical manipulation. Methods of analysis are also given, 

 and in such a manner as to be intelligible to the manu- 

 facturer as well as to his chemist. 



The manufacture of varnishes, by M. Naudin, is 

 divided into two parts, the first treating the theoretical 

 side and including the analysis of the resins and oils, 

 with brief notice of the manner of extraction of the same, 

 and their origin both geograjjhical and botanical. The 

 second part treats of the princij)al processes of manufac- 

 ture actually used in this branch of industry. 



The art of china and pottery decoration is so wide- 

 spread and includes among its devotees so many ama- 

 teurs, as well as those working upon a larger scale. 



that this little boot of M. Guenez will doubtless prove 

 jjrofitable to many readers. Those "little points" which 

 one soon discovers to be so essential to success are here 

 described in principle and in practice, and by an under- 

 standing of the cause of the failure repeated disap- 

 pointment is avoided. In pursuance of this p>lan the 

 first part of the book deals with the theory or chemis- 

 try of china painting, while the second describes in de- 

 tail the methods used in practice. While sufficiently 

 pojjular to prevent no serious difficulties to the ama- 

 teur, this book is of greatest value to the industrial 

 worker. 



NOTES AND NEWS. 



Mrs. J. E. Geeen's "Town Life in the Fifteenth Cen- 

 tury" is nearly ready. It will be of undoubted interest 

 to the general reader as well as to the student of polit- 

 ical economy, dealing, as it does, with the days when the 

 towns were independent communities and centres of polit- 

 ical life. "There is nothing in England to-day," writes 

 Mrs. Green, "with which we can compare the life of a 

 fully enfranchised borough of the fifteenth century, . . , 

 a state within a state, boasting of rights derived from 

 immemorial custom and of later privileges assumed by 

 law." 



— Mr. J. Norman Lockyer, the author of "The Meteor- 

 itic Hj'i5othesis," "The Evolution of the Heavens and the 

 Earth," and many other important works, has in press a 

 new book, "The Dawn of Astronomy." It tells of the 

 days when wonder and worship formed the prevailing 

 feature in any consideration of the heavenly bodies; and 

 it traces in Egj'pt and Babylonia, in China and India, the 

 beginnings of the scientific treatment of the subject. The 

 numerous illustrations lend another feature of interest to 

 this delightful book.
