lit' then takes thu reader through the fliffereiil ty|jes 

 of scenery, commencing with mountains, that occiipy 

 three chapters. These are followed by two others 

 on valleys and a like space on lakes. 'I'lic rest of 

 the chapters are devoted to volcaiioes, plains, and 

 plateauN, deserts, frost, snow and ice, (jlaciers and 

 ice-sheets, siyns of former glaciation, oceans ; and, 

 finally, a general conclusion. In discussing these 

 subjects Mr. Marr has given many of his instances 

 from our own islands, but has necessitrily had to go 

 abroad for others. .Ml are clearly illustrated by 

 reproductiotu of photographs taken in some cases 

 for the purpose. We give one exan^ple, with the 

 permission of the publishers. It is a view of High 

 I'orce in Yorkshire to show one form ol valley 

 making. The other illustrations are varied views, 

 each given with a \\cvi of explaining the forma- 

 tion of scenery. Thus in a small compass we have 



in the microscopical world ; whilst the printing, [uipcr, 

 and U-aulifully pro<luced illuslrolionii relleri the 

 greatest credit upon all concerjicd in the publication. 

 We miss in the present volume l>r. Jleiiri Van 

 Ileurck's re\iew of microscope, and appiratus during 

 the preceding year, but the piil. libbers have left the indi- 

 vidual makers to speak for llll-lll^elves as lo their own 

 pr(xluctions, and the plan seems to have worked well. 

 We have not spare to mention in 'kiail the long list 

 of contributors and their respective uticlcs ; but we 

 may refer to ai:oloured plate, with kc;. illustrative of 

 pond-life, whiili will interest beginiK i , in this hunt- 

 ing-ground so dear to the amateur mic r.iscopist, and 

 al.so lo a coloureil drawing of a hyaline daphnia, 

 as shown by dark-ground illumination, due to .Mr. 

 I)- J. .Scourfield. This drawing is really ipiite a 

 work of art. Among other interesting articles we 

 may mention a further contribution by Mr. lulius

a book that will give food for thought to any of 

 us who care to trouble lo know more than hitherto 

 about either familiar surroundings or the places we 

 see in our travels or of which we read elsewhere. Il 

 is a good book and one sure to be largely read.

 9j in. x7 in., with 7 plates (2 coloured) and 115 

 other illustrations. (London: I'ercy Lund, Hum-

The large sale of the 1S99 .\nnual h.is evidently 

 justified the publishers in continuing their venture, 

 and the present Annual is in no way inferior to its 

 ])redecessor either in \ariety of interest or in ap- 

 pearance. The rontriliutors are writers well known 



Rhinebergon Mulliple Colour Illumination ; anarlicle 

 on "Some Molhisca and the Microscope," by Mr. 

 Wilfred Mark Webb, with micro-photographs of 

 odontophores, etc., by Messrs. F. Noad Clark and 

 William Moss respectively : an illustrated note on the 

 genus Arrcnui'Hs of Fresh-water Mites, by Mr. Chas. 

 I). Soar ; and an article on Dental Hislolog>- that 

 will be of service to many workers in this field of 

 research. There are several very practical notes on 

 photo-micrography, including one on chromo-photo- 

 micrography. In fact, the varied contents will in- 

 terest all microscopists, and we can strongly recom- 

 mend the volume to their notice. We are glad to see 

 this second year's issue and IrusI the " .\nnual of 

 Microscop)'" has come t'> slnw 1''. S. S.
