APPENDIX B. 



As frequent references have been made in the body of the Bulletin 

 to methods of analyses and manner of judging adapted by European 

 chemist for beer and wine, I have thought it proper to give some of 

 these methods complete. They represent the conclusions of chemists 

 who have devoted their lives to the study of this branch of work, and 

 may very properly be taken as a guide by those of us who have occa- 

 sion to follow the same line of work in this country, where beer and 

 wine analysis has as yet had little application. 



The translation has been made as literal as possible. 



The following are the methods adopted by the Berlin Commission: 1 



A commission of experts, appointed iu the year 1884 by the chancellor of the Empire, 

 to which was intrusted the establishment of uniform methods for the chemical inves- 

 tigation of wine, adopted the following resolutions, which wore made public by (In- 

 Prussian minister for commerce and trade by a decree of the 12th August, 1834, which 

 provides that they shall be rigidly adhered to iu public institutions for the exami- 

 nation of food-stuffs, and are recommended to the representatives of like private con- 

 cerns : 



RESOLUTIONS OF THE COMMISSION FOR ESTABLISHING UNIFORM 

 METHODS FOR THE ANALYSIS OF WINES. 



Since, in consequence of improper manner of taking, keeping, and sending in of 

 samples of wine for investigation by the authorities, a decomposition or change in the 

 lattt-r often occurs, the commission considers it advisable to give the following in- 

 structions : 



INSTRUCTIONS FOR SAMPLING, PRESERVING, AND SENDING IN OP SAMPLES OP WINE 

 FOR EXAMINATION BY THE AUTHORITIES. 



(1) Of each sample, at least one bottle (f liter), as well filled as possible, must bo 

 taken. 



(2) The bottles and corks used must be perfectly clean; the best are new bottle? 

 and corks. Pitchers or opaque bottles in which the presence of impurities cannot be 

 seen arc not to be used. 



(3) Each bottle shall be provided with a label, gummed (not tied) on, upon which 

 shall be given the index number of the sample corresponding to a description of it. 



(4) The samples are to be sent to the chemical laboratory as soon as possible to 

 avoid any chance of alteration which, under some circumstances, can take place in a 

 very short time. If they are, for some special reason, retained in any other place for 

 any length of time, tho bottles are to be placed in a cellar and kept lying on their 

 sides.
