 Rothamsted for analysis. 



The results are summarised in the following ta1)le, which 

 shows for each sample the changes during the various stages, 

 as calculated back to 100 parts in the original material.

For example, dealing with sample No 1, we see that 100 

 parts of grain yielded 79 parts of malt and '2'2 of malt dust, a 

 loss of weight of nearly 19 per cent. This loss was, however, 

 largely water, for the next row of figures shows that of 100 

 parts of dry matter in the original material 91*8 were recovered 

 in the malt and malt dust. During steeping 0*4 per cent, of dry 

 matter was lost, consisting of mineral matter (largely dirt 

 washed ofi" the grain), a little nitrogenous matter, and the ready- 

 formed sugar in the barley. During the process of growing on 

 the floor something over 4 per cent, of dry matter is lost ; the 

 table, for instance, shows a fall from 99*6 parts of the original 

 dry matter to 95-9 parts, by the eighth day. This loss is due to 

 the respiration process accompanying growth, and represents
