 employed." 



In Dr. H. BUNGENER'S treatise " La levure de la biere," 

 1890, T the following statement occurs, contrasting the old 

 with the new period : "In France, HANSEN'S system has been 

 eagerly taken up by L. MARX, A. FLUEHLER, and KOKOSINSKL 

 In some breweries, it has been recently introduced, and it will 

 soon be adopted by others. We are convinced that its intro- 

 duction into all the larger breweries of France, and in fact 

 everywhere else, will only be a question of time. It has in 

 fact been established, that it ensures regular working and a 

 good result in one of the most important stages of the manu- 

 facture, where hitherto chance and, consequently, uncertainty 

 also prevailed." 



Prof. C. J. LINTNER, of the Technical College, Munich, 

 writes (18 9 1) 2 : "In the abstracts relating to advances in 

 the brewing industry, the epoch-making investigations of the 

 Danish savant EMIL CHR. HANSEN, and their application in 

 breweries, have been frequently reported. A connected 

 account of HANSEN'S reform and methods, however, has not 

 yet appeared in this journal, though such an account would 

 be by no means undesirable, considering the great importance 

 which the subject has acquired during the seven years since 

 its introduction into the brewing industry. Hitherto, the 

 brewery has mainly benefited from HANSEN'S system, which, 

 however, has already found its way into the distillery and 

 pressed-yeast factory, and these branches of the fermen- 

 tation industry will also be greatly benefited by its intro- 

 duction." 



In England some of the most celebrated authorities have 

 frankly acknowledged the value of HANSEN'S investigations. 

 Amongst these is Professor PERCY FRANKLAND, who has ex- 

 pressed himself as follows : 3 



" EMIL CHRISTIAN HANSEN, of Copenhagen, has enormously 

 extended our knowledge of the alcohol-producing organisms or 

 yeasts ; he has shown that there are a number of distinct
