366 INDEX, 



double motives, for the refreshment of the mental, and of 

 the bodily frame ; want of it produces madness ; procured 

 to man with more difficulty than to other animals ; in what 

 manner sleep fetters us for hours together, according to 

 Rohault ; care required to regulate its quantity, and why ; 

 bodily labour demands a less quantity of it than mental ; 

 the famous Philip Barrettier slept twelve hours in the 

 twenty-four; sleep to some an agreeable period of exis- 

 tence ; questions treated in the schools to this purpose ; 

 numberless instances of persons who, asleep, performed 

 many ordinary duties of their calling, and, with ridiculous 

 industry, completed by night what they failed doing by 

 day ; remarkable instance related in the German Epheme- 

 rides, ii. 10. See Arlotto. 



Slot, term for the print of the hoof of the stag ;. to draw on 

 the slot, a phrase among hunters, ii. 317. 



Sloth, different kinds of that animal described : seem the 

 meanest and most ill-formed of all animals that chew the 

 cud: their food: formed by nature to climb: they get up 

 a tree with pain, but, utterly unable to descend, drop from 

 the branches to the ground : move with imperceptible 

 slowness, baiting by the way : strip a tree of its verdure in 

 less than a fortnight, afterwards devour the bark, and in a 

 short time kill what might prove their support : every step 

 taken, send forth a plaintive melancholy cry, which, from 

 some resemblance to the human voice, excites a displeasing 

 pity : like birds, have but one vent for propagation, excre- 

 ment, and urine: they continue to live some time after 

 their nobler parts are wounded, or taken away : their note, 

 according to Kircher, an ascending and descending hexa- 

 chord, uttered only by night : their look piteous, to move 

 compassion : accompanied with tears, that dissuade injuring 

 so wretched a being : one fastened by its feet to a pole, 

 suspended across two beams, remained forty days without 

 meat, drink, or sleep : an amazing instance of strength in 

 the feet, iii. 406. 



Slow, name given by some to the blind-worm, v. 375. 



Smelling, the sense in which man is most inferior to other 

 animals : it never offends them : stronger in nations abstain- 

 ing from animal food than in Europeans : Bramins of India 

 have a power of smelling, equal to what is in other crea- 

 tures: can smell water they drink, to us quite inodorous : in 

 a state of nature useful, not in our situation : gives often 

 false intelligence: natives of different countries, or different 

 natives of the same, differ widely in that sense : instances 

 of it : mixtures of bodies void of odour produce powerful 

 smells : mixtures of bodies separately disagreeable, give 

 pleasant aromatic smells: a slight cold blunts all smelling: 

 incurable aversions to smells formerly agreeable, retained
