Alio tunc vul¬ nere perforaui cerebellum, inftrumento adadto per offis occipitis inferiorem lateralem partem, a finiftris dex- trorfum, deorfum.

Quo vifo, decreui experimenta capere ^circa neruos diaphragmaticos. Thorace aperto, omnia ca- daueris inftar frigebant, refpiratio tamen & cordis mo¬ tus pergebat. Neruo diaphragmatico digitis fortiffime comprefio, & fupra comprefiionem irritato, diaphra¬ gma conftringebatur, ligaui neruum, fupra ligaturam irritaui, nulla autem inde lecuta elt diaphragmatis con- cudio. Infra ligaturam vero irritato neruo, diaphragma contrahebatur. Amputaui neruum, abscidam; partem irritaui, fubfecuta femper diaphragmatis contractione. Idem obferuaui altero in latere. Conftringebatur dia¬ phragma, iiue neruum furfum, fiue deorfum ftringerem. Aperto cranio vidi, vulnus priori vice inflictum per me- duilofani cerebelli fubftantiam in cerebrum vsque pene- traffe, alterum vero vulnus paulo inferius a latere per medullam cerebelli, tranliens ventriculum quartum, ad latus capitis oppofitum progrdlbm ede, Ventriculus quar¬ tus grumo fangu-inis refertus, & medulla {pinalis vndique {anguine circumfufa fuit, D 5 Exper.
