    Soemmerring, Bichat, Malacamc, and others, are brought forwards when ne- cessary to settle some disputed point; and with such a degree of ingenuity, without pretension, which is indeed highly creditable to the author. He. does not, then, come forward as a discoverer of new things, but mo- destly exposes the ingenious deduc- tions of bis patient and extensive in- quiries on the structure, distribution, connexions, and functions of those parts which make the subject of his work. Of the correctness of my as- sertion, every one may have a convinc- ing proof, from the very beginning of the already-mentioned chapter. §. I. “ Disputatissimam aggressurus partem, ommno certa non proferam, satis, si quae probabili magis conjectura, assequi licet, afferam. Vidimus porro in pracedenti dissertatione, quintum par multiplicibus in partihus inseri, quarum omnino varii sunt usus. Sunt, quae seu- sui obediunt voluntario, sunt qute iuvo- luntarie, vel antomatice moventurpartes, sunt tandem, quae secretionibus dican- tur; omnes denique partes vitam vivunt organicam. Sed quasnam exequitur actiones quintum par? Defiuituri, antea consulamus auetores. §■ II. Galeuus jam tradidit, nervum quinti paris, quem sub nomine terliae conjugationis designat, sensui tactus, et motus voluntario dicatum esse, in super et ramos qui in toto ore distribuuntur gustui inservire.”—(De usu partium, lib. ix. et xi.) “ Willis docuit, sensibus famulari quintum par, tactus scilicet, et gustus; motus etiam, sed involuntarios, vel ab instinctu perficere, asseruit; sympa- thice, quoque, et pathetice affici, atque moveri: actionibus etiam involuntariis (sivc organicis functionibus) dicatum esse ramum lacrymalem ophthalmici, aperte iunuit, visui quodammodo, et olfactui inservire; sanguinis circulatio- nem in facie immutare*.”—pp. 119,120, (Cerebri Anatomes, cap. xvii.; Nervor. Descript, et Usus, cap. xxii.) And so on, with Vieussens, Meckel, Soemmerring, Bichat, Gall, and Boyer. § I IT. “ Multiplicatas igitur adnio- dum, diversique ordinis exequitur func- tiones, secundum memoratos auetores, quintum par.
