Page 104 - Hark, how the chairs and tables crack, Old Betty's joints are on the rack; Loud quack the ducks, the peacocks cry, The distant hills are looking nigh. How restless are the snorting swine, The busy flies disturb the kine; Low o'er the grass the swallow wings ; The cricket, too, how sharp he sings ; Puss, on the hearth, with velvet paws, Sits, wiping o'er her whiskered jaws.
Page 23 - Let us start at the moment when the first element came into existence. Before this time matter, as we know it, was not. It is equally impossible to conceive of matter without energy, as of energy without matter. From one point of view the two are convertible terms. Before the birth of atoms all those forms of energy which become evident when matter acts upon matter, could not have existed — they were locked up in the protyle as latent potentialities only.
Page 162 - According to Fleischl, the shock of the blood sent into the capillaries at each cardiac systole has a mechanical action in aiding the chemical processes of tissue change in somewhat the same way, though to a less extent, as a blow upon a percussion cap. If a heart is too feeble or the resistance in the vessels too great to allow the blood entering the aorta at each systole to give a distinct forcible impulse to the blood present in the arteries, the chemical changes in the tissues will be sluggish...
Page 43 - This enzyme can be isolated, and its peptonising action demonstrated apart from the microbes which produce it. 3. The most active enzyme is that formed in meat broth. 4. Acidity hinders, alkalinity favours its action. 5. The bacteria which form a peptonising enzyme on proteid soil can also produce a diastatic enzyme on carbohydrate soil. * ' A,-mil cm in dei Lincei, Rendiconti,
Page 43 - Rendiconti,' vol. 3, sem. 1, 1887, p. 535. 6. The diastatic enzyme is not so readily separated from the microbes which produce it, but where that has been accomplished its action on starch can still be demonstrated. 7. The diastatic enzyme has no effect on gelatine, and vice versa. 8. The bacteria are capable of evincing an adaptiveness to the soil in which they grow. 9. The microbes are capable of digesting other similar bodies sach as dextrose and muscle.
Page 24 - ... uranium (240). This oasis and the blanks which precede and follow it may be referred with much probability to the particular way in which our Earth developed into a member of our solar system. If this be so it may be that on our Earth only these blanks occur, and not generally throughout the universe. What comes after uranium ? I should consider that there is little prospect of the existence of an element much lower than this. Look at the vertical line of temperature slowly sinking from the upper...
Page 132 - Sulfonal appears to be one of the most effective of all the newly introduced hypnotics, and although it does not, like morphine, compel sleep, it induces sleep in a pleasan.t manner, and has few disagreeable effects and little or no danger.
Page 107 - Thus in the case of the alkyls their action differs according as they are combined with hydrogen in the hydrides, with hydroxyl, OH, in the alcohols, or with both oxygen and hydroxyl, as in the acids. Moreover, both their physical condition and physiological action may be changed by replacing hydrogen by other elements. Thus, if we replace three atoms of hydrogen in marsh gas...
Page 42 - Ferment Action ot Bacteria." By T. Lauder Brunton, MD, FRS, and A. Macfadyen, MD, B.Sc. The chief objects of this research were, (A) to discover whether microbes act on the soil upon which they grow by means of a ferment ; and (B) whether such a ferment can be isolated, and its action demonstrated on albuminoid gelatine and carbohydrates, apart from the microbes which produce it, in the same way that the ferments of the stomach and pancreas can be obtained apart from the cells by which they were...
Page 153 - Ammonia. Phenylacetamide. Aniline. Acetanilid. acetyl. You will see from its formula that it may be regarded as ammonia, in which one atom of hydrogen is replaced by phenyl, and another by acetyl. When regarded from this point of view it is called phenylacetamide. But it may be regarded also as benzene in which one atom of hydrogen has been replaced by...
