We must in the meantime remark, that if touch has acquired a great development as a muscular power, civilization has done almost nothing for it as an organ of sensation.  We must, however, despair of nothing, but remember that the human race is yet young, and that only after a long series of years can the senses aggrandise their domain.

For instance.  Harmony was only discovered about four centuries ago, and that celestial science is to sound what painting is to colors.

Certainly, the ancients used to sing and accompany themselves in unison.  Their knowledge, however, ended there.  They knew neither how to decompose sounds, nor to appreciate their relations. [Footnote:  We are aware that the contrary has been maintained; the idea though cannot be supported.  Had the ancients been acquainted with harmony, their writings would have preserved some precise notion on the matter, instead of a few obscure phrases, which may be tortured to mean anything.  Besides, we cannot follow the birth and progress of harmony in the monuments left to us; this obligation we owe to the Arabs, who made us a present of the organ, which produces at one time many continuous sounds, and thus created harmony.]

Tone was only reduced to system, and accords measured in the fifteenth century.  Only then it was used to sustain the voice and to reinforce the expression of sentiments.

This discovery, made at so late a day, yet so natural, doubled the hearing, and has shown the existence of two somewhat independent faculties, one of which receives sound and the other appreciates resonance.

The German Doctors say that persons sensible of harmony have one sense more than others.

Of those persons to whom music is but a confused mass of sounds, we may remark that almost all sing false.  We are forced to think that they have the auditory apparatus so made, as to receive but brief and short undulation, or that the two ears not being on the same diapason, the difference in length and sensibility of these constituent parts, causes them to transmit to the brain only an obscure and undetermined sensation, like two instruments played in neither the same key nor the same measure, and which can produce no continuous melody.

The centuries last passed have also given the taste important extension; the discovery of sugar, and its different preparations, of alcoholic liquors, of wine, ices, vanilla, tea and coffee, have given us flavors hitherto unknown.

Who knows if touch will not have its day, and if some fortuitous circumstance will not open to us thence some new enjoyments?  This is especially probable as tactile sensitiveness exists every where in the body, and consequently can every where be excited.

We have seen that physical love has taken possession of all the sciences.  In this respect it acts with its habitual tyranny.

The taste is a more prudent measure but not less active faculty.  Taste, we say, has accomplished the same thing, with a slowness which ensures its success.
