but it must be borne in mind that it is only on the condition 

 of the food being digested and passed into the blood, that the 

 results given in these Tables are realized. If, for instance, saw- 

 dust or paraffin oil had been experimented upon, numbers would 

 have been obtained for these substances, the one about equal to 

 that assigned to starch, and the other surpassing that of any 

 article in the Tables ; but these numbers would obviously have 

 been utterly fallacious, inasmuch as neither sawdust nor paraffin 

 oil is, to any appreciable extent, digested in the alimentary 

 canal. Whilst the force-values experimentally obtained for the 

 different articles in these Tables must therefore be understood as 

 the maxima assignable io the substances to which they belong, 

 yet it must not be forgotten that a large majority of these sub- 

 stances appear to be completely digestible under normal cir- 

 cumstances.
