Mr. Flatters can. The book is divided into ' General 

 Remarks ; ' ' Collection and Preservation of Specimens, &c. ; ' 

 ' Tools and Methods of Work ; ' ' Stains, Reagents, Mounting 

 Media, Cements, &c. , their Formulae and Manipulation;' 

 •Mounting Media;' 'Cements;' and 'Instructions for the 

 Preparation of Types.' Each of these contains the results of 

 Mr. Flatters' extensive experience, the full benefit of which can 

 be derived by all who use the book. As the author points out, 

 'had such a work been at his service twenty years ago, he would 

 have been spared years of persistent hard work and many dis- 

 appointments.' The first part of the book is illustrated by 

 numerous diagrams and blocks from photographs, by the aid 

 of which both beginner and expert will alike derive much 

 benefit. 



SECTION OF SYCAMORE. 



But it is in the 85 coloured illustrations of botanical sections, 

 enlarged by the microscope, that the charm of the book lies. 

 These are arranged upon twenty-three large plates, and the 

 manner in which they have been reproduced, showing the 

 effects of various stains, reflects the greatest credit upon all 

 concerned. By the kindness of the publishers, we are able to 

 give our readers a specimen illustration (see Plate I.), but even 

 this does not do justice to the work. In the first place the 

 detail and eff"ect of the plates in the book itself are not marred 

 by the reference numbers, which are there printed in outlines on 

 transparent paper, which covers each plate ; and, secondly, the 

 descriptive letterpress appears on a separate page facing each 

 plate. The appearance of the illustrations is thereby much 

 improved. Not only do these show the proper method of 

 cutting and staining sections, but they will be of the greatest 

 service to all interested in vegetable histology. 



THE DONCASTER EARTHQUAKE. 



In a paper recently read to the Geological Society, of London, 

 Dr. C. Davison described the Doncast Earthquake of April 25th 

 1905. He pointed out that the Doncaster earthquake of 1905 was 

 a twin, with its principal epicentre half a mile north of Bawtry, and 

 the other about 4 miles east of Crowle and close to the centre of 

 the disturbed area of the Hessle earthquake of April i ^tli ic)02.* 

 The distance between the two epicentres is about 17 miles.
