Practical Microscopy. By George E. Davis, F.R.M.S., 

 PM.C, etc. etc. New and revised edition. Svo, pp. viii. — 436. (London : 

 W. H. Allen. 1889.) 



We are pleased to welcome a new and revised edition of this very useful 

 book. The aim of the author has been to furnish such information as would 

 enable the microscopist to thoroughly understand the instrument, and the 

 principles on which it is constructed, and to initiate him into the art and 

 mystery of those operations which go hand in hand with scientific enquiry. 

 The work is illustrated with 310 illustrations and a coloured frontispiece, 

 showing fine double-stained sections of typical forms of wood, viz., Clematis, 

 Dog Rose, Eucalyptus, Gout Weed, and Black Pepper. A number of recipes 

 at the end of the book will doubtless be found useful. 



A Monograph of the British Uredine^ and Ustila- 



tUNE.*:, with an account of their biology, including the methods of observing 

 the germination of their spores, and of their experimental culture. By Charles 

 B. Plowright, F.L.S., M.R.CS., etc. etc. Svo, pp. viii. -347. (London: 

 Kegan Paul, Trench, & Co. 1889.) Price 12s. 



We have here the Uredinere and Ustilaginece very carefully described, also 

 an account of their life-history, as far as it is at present known. At the cost of 

 much labour and a considerable expenditure of time, the author has compiled 

 from the various handbooks, transactions, periodicals, and other sources, the 

 materials found in the pages of this work. The result being a very exhaustive 

 treatise on this branch of the fungus kingdom. The book is illustrated with 

 wood-cuts and eight lithographic plates.
