According to the standards, a pure cider vinegar is laevo-rota- 

 tory and the solids should not be more than 50 per cent reduc- 

 ing sugars. Most of the results obtained on the cider vinegars 

 made outside of the State come within the range of these stand- 

 ards but in a few instances there are considerable deviations. 

 For instance No. 7740 gives a right hand polariscope reading 

 and No. yyy^ a zero reading. In other respects these vinegars 

 conform to the standards. It, however, will be noticed among 

 the country vinegars which we have no reason for thinking 

 sophisticated in any way, there are two samples that give right 

 hand readings. It is very difficult to understand why these two 

 samples of country vinegar should give positive readings with 

 the polariscope. 



To some extent the sugar content of the solids is a distin- 

 guishing factor between genuine and spurious vinegars. The 

 results of the analyses for the imported vinegars averaged 

 higher than those of the country vinegars and in two instances 

 they exceed 50 per cent. Some authorities consider
