is no point, no sest of the soul ; the pineal gland, meninges, &c. 

 are all visionary notions. Tft see with tKO eyes, and hear with 

 two ears hettcr than witli one. Sometimes the senses are pas- 

 Siive ; but whenever tlie mind is active only one sense is engaged j 

 shadows always fall on one eye, we see with two eyes but look 

 with onlv one ; we hear with both ears, but listen with one. 

 Animals as well as men prove this by the inclination of their 

 heads when listening. The greater number of persons use the 

 right eye, which is generally stronger, and often larger than the 

 left. Hands are stronger by exercise ; and most children use 

 the right without anv instruction. Disease is more frequent in 

 the left than right side : hump-backs are on the left side. TJie 

 same reason must exist for the action of the passi-i e as the active 

 senses. The functions of the five senses are mediate or imme- 

 diate ; the greater number is mediate and result from the exer- 

 cise of the internal senses. The exercise of an external senser 

 indicates the activity of internal power. No sense or faculty has 

 two kinds of functions. It is the internal faculties which exer- 

 cise the external senses ; for seeing only refers to colours, hear- 

 ing to sounds. The five senses are insufficient to explain the 

 source of all our knowledge : thev only recei\ e impressions but 

 do not produce perceptions. Examples ; some persons have 

 great brilliancy, have in some degree universal knowledge, and 

 yet are not profound thinkers. The French are distinguished 

 for this brilliancy. Some animals are naturally tameable, others 

 are not, and if an individual be domesticated its oifspring is 

 wild ; hence we lenrn that one species has not proceeded from 

 anotiier. Dogs are debarred the houses in EgJ'pt as unclean, 

 and yet they are tame. The biain of the tyger inclines down- 

 wards bcliind, that of the polecat is nearly horizontal, that of 

 the otter is more elevated behind, and it is tamed ; the fox has 

 the brain still more elevated ; the dogs from the greyhound to 

 the tarricr and pug, gradually rise ; monkies still more so, and 

 the orang outang lias a forehead approaching that of some mid- 

 dling men ; in like manner the brain of caribs, some negroes, 

 and idiots, is flat. Lord Bacon had the highest and greatest 

 forehead ever seen ; the Jupiter of the ancients only equal to it. 

 The primitive faculty however is not yet known A ridge over 

 the nose and evebrows at the base of the forehead indicates bril- 

 liant m.en or per'-cns of knowledge, men of fact. This deviation 

 is found in cliildren who look at every thing till nine or ten 

 years of age, when it disappears in consequence of the devolop- 

 meut of the other organs. This faculty, the first of the knowing 

 or perceiving ones ; and XlXth configuration, gives a knowledge 

 of the external \torld ; it is the organ ofindividualily, as it re- 

 members
