UI. Another advantage of the form of report suggested is that the 

 purity report would afford a fairer index of foreign ingredients. 



Conventional impurities are not in accordance with the real meaning 

 of the term. 



Seeds should be taken in their com.mercial sense to designate that 

 which is sold as representing the portion of the plant wliich is utilised 

 for sowing to reproduce the species. The term should be accepted as 

 descriptive of the whole or any portion of a seed of any species as com- 

 mercially understood and as commonly collected and marketed. Thus, 

 broken seeds, shrivelled seeds, deaf seeds, immatxire seeds, seedless clusters 

 of Beta should not be regarded as impurities. They are of the species 

 they presume to represent and, moreover, they are the commercial article 

 which they are represented to be, andj consequently, should not be 

 designated impurities. 



Conversely the " purity " of a sample which is determined by sub- 

 tracting these from the total is somewhat misleading. 



It is to be deprecated that any special or arbitrary significance should 

 attach to a word which has a commonly accepted meaning. 



The issue of partial reports, whether of pxirity only or germination 

 only, is to be deprecated and certainly a report on germination only 

 should never be issued.

In commenting on his paper, Mr. Anderson stated that his 

 point of view represented that of the consumer who was engaged 

 in the production of pastures and whose interests, he thought, 

 had been insufficiently considered by Seed Testing Stations. His 

 proposal, which should be regarded as tentative because the 

 evidence was incomplete, might conflict with established regula- 

 tions, and did, in fact, conflict with the official regulations in force 

 in Great Britain. He suggested, however, that the proposal 

 might be useful to any Committee which might be appointed to 

 draw up a scale of international latitudes and common rules of 

 analysis. If the main general principle embodied in his proposal 

 were accepted, he was prepared to coUect complete evidence
