[29] See Œc. R. A. Vol. II., Nos. 100, 101, 191; ›Quod sensationes externae non ad ulteriores metas quam ad sphaerulas corticales pertingant, id satis in confirmato est, quando hae fibrarum nervearum et medullarium sunt principia›; and 113, 130, 140, 141, etc. See also ›The Brain› No. 98. [30] As observed in Quain’s ›Elements of Anatomy›, Tenth edition, edit. by E. A. SCHÄFER and G. D. THANE, Vol. III., Part. I, p. 39: ›The term medulla oblongata, as employed by WILLIS and VIEUSSENS, and by those who directly followed them, included the crura cerebri and pons Varolii, as well as that part to which by HALLER first, and by most subsequent writers, this term has been restricted.› [31] See Œc. R. A. Vol. II., Nos. 83-85, 91, 93, 95, 114, 140: ›Proinde cum totidem origines motus sunt, quot sphaerulae istius substantiae;› and 144, 146: ›Sic distinctissime quaevis (sphaerula) suam fibrulam animat & usque ad ejus finem in fibram corporis motricem influit;› 157 and 191-194-95, 202 etc. See also ›The Brain›, No. 399. [32] So, for example, in Œc. R. A. Vol. II., No. 100: ... ›quod Cortex sit principalis totius Cerebri substantia; in ipso termino primo Fibrarum et ultimo Arteriarum sita; See also Œc. R. A. Vol. II., 111-116, 133, 134, 138, 152, 197, 290, etc., or, for example, Œc. R. A. III., No. 127, fin., and No. 404, where we read as follows: ›Ex anatome Cerebri id constat, quod Cerebrum, seu substantia ejus corticalis, quae proprie cerebrum audit, sit _Sensorium commune_, nam quinque organa suos sensus externos ad corticem ut ad suum sensorium commune et unicum internum referunt. Cerebrum corticale etiam est _Motorium commune voluntarium_, quicquid enim agendum est mediantibus nervis et musculis, id praevia voluntate a cerebro determinandum est.› [33] Œc. R. A. II., 107: ›Partes hujus substantiae — — — merentur _Organa Sensuum interiorum_ et Cerebellula nuncupari, nam media substantia medullari et sanguine ab Organis externis alluentes modos et tactus recipiunt, et ad judicem animam referunt.› See also Œc. R. A. 191, 192, Œc. R. A. II., 195: — — ›Substantiae Corticales totidem sunt Cerebellula, — —; singula enim sensorium est in particulari, quale est Cerebrum in communi.›
