PREFACE TO ENGLISH EDITION. XI 



feature peculiar to the English edition, more particularly the 

 rendering into the equivalents, with which, unfortunately, 

 practical men on this side of the channel are still most at home, 

 of the metric weights and measures and centigrade tempera- 

 tures, as well as the Index which Mr. Robb has compiled, will, 

 I trust, render the book of still greater service than it other- 

 wise would have been to many of those who may favour it 

 with their attention. 



The debt which we English brewers owe to M. Pasteur can 

 hardly be over-estimated, and I must be allowed here to express 

 my personal obligations to that distinguished worker for the 

 permission which allows this translation ; and to the French 

 publishers for their help with regard to the interleaved 

 illustrations. 



The author's preface and dedication are, of course, reproduced, 

 the former making it unnecessary for me to refer more in detail 

 to the contents of the translation.
