Not illustrated. 1903 edition. Excerpt: ...to the thorough and vigorous digestion of farinaceous foods by the saliva. This obviously may be a matter of little moment to a vigorous person with abundant digestive resources, but to the weak and ailing individual with scant digestive powers it may be a matter of vital importance. The general tenor of our conclusions in this direction is in close harmony with the observations of Sir William Roberts. Thus, this investigator states that "both the stronger and the lighter wines show a powerful inhibitory effect on salivary digestion. Even so small a proportion as one per cent, of sherry or hock was found to paralyze saliva almost completely, and even one quarter of this proportion delayed the achromatic point appreciably. Claret and port wine behaved similarly. The inhibitory effect of wines is entirely due to the very considerable degree of acidity which they all possess.... When the acidity of wines is neutralized they lose entirely their inhibitory effect on salivary digestion." Further, in writing of the action of malt liquors, Roberts states, as the result of his experiments, that " malt liquors were found to hamper salivary digestion exactly in proportion to their degree of acidity." Robertson,1 in his recent work on the salivary digestion of starch, reports that "wines have a very marked inhibitory influence on the digestion of starch by saliva, and this is almost wholly due to their acidity." Alcohol, he states, even in dilute solution, " retards salivary digestion of starch, but the action is much less marked than in the case of infusions of tea." Lastly, the same author states that " beer promotes the salivary digestion of starch," a conclusion which our results hardly confirm. It should...show more
