LINSEED MEALS. 25 



amount of protein, but this has no significance when it is noted that 

 other samples of the same product have a satisfactory compo- 

 sition. Sample No. 1791 also has a somewhat low protein content; 

 since, however, all other determinations on this sample are al><>\< 

 suspicion, no significance is to be attached to the low protein 

 content. 



Because of the name and microscopical examination, sample No. 

 1971 was classed under linseed meals, although its low 'protein and 

 high starch content show that it is not straight linseed meal. The 

 microscopic examination shows the presence of a wheat product. 



A considerable number of the samples examined contain a smaller 

 percentage of fat than is given in any of the, compiled averages, but 

 they are not so much below the averages as to excite suspicion, 

 except in two cases, namely, Nos. 1927 and 1797. Sample No. 1927 

 would appear from tjae fat figures to be made according to the new 

 process. No. 1797 contains considerably less fat than the average 

 linseed meal. Since, however, three other samples of the same goods 

 contain a satisfactory amount of fat, it is probable that the low fat 

 content in this single sample has no significance. 



The microscopical examination of this group of samples shows 

 that the majority of them contain weed seeds in greater or less 

 abundance. Small amounts of the various weed seeds are to be 

 expected, and it is only when they are of a poisonous variety or in 

 excessive quantities that their presence is reprehensible.
