The present, being the .second part of an enquiry into the 

 sugar strength and acidity of Victorian musts, is the third part 

 of a general investigation of Victorian wines — the first part of 

 which related solely to the alcoholic strength of Victorian and 

 other Australian wines. In the first part it was shown from the 

 determination of the alcoholic strength of some 600 Australian 

 Vfiwe.^ (Jonrnat of the Board (?f Viticulture for Victoria, May 1892, 

 pp. 81-96), that the average strength of Australian wines is 12 

 grammes of absolute alcohol per 100 cubic centimetres, as 

 compared to an average of 8 grms. per 100 c.c. characteristic of 

 French and German wines (nearly 2000 samples). In the second 

 part, which was connnunicated to the Chemical Section of the 

 Aust. Assoc, for Ad. Science, Adelaide, 1893, the investigation 

 of the musts was taken up with a view to ascertaining in the 

 first place whether the sugar strength of Victorian musts 

 was great enough to account for the high alcoholic strength 

 of Victorian (and all Australian) wines, and also to 

 determine how the acidity of Victorian nmsts compared with 

 those of France and Germany. In the present third part the 

 results of the determinations of sugar strength and acidity of 

 Victorian musts for the Vintage of 1894 are communicated, as it 

 appeared desirable to control the determinations of the vintage 

 of 1893 by a second and more extensive series in a different 

 season and in more widely scattered districts. For the purposes 

 of comparison and completeness the results of 1 893 will be 

 reproduced and discussed along Avith those of 1894. 



It was found in the first part that the Victorian wines showed, 

 on the average, an alcoholic strength half as large again as that
