De acu triquetra elaftica eiusdemque vfu, in 
'cura hydroceles cet. au&ore 10. andre'e. 
A d commoda huius acus Cl. Auflor refert, quod 
applicari poflit, quamuis etiam tumor fcroti 
non adeo fuerit magnus, quod vulnus ab ipfo in- 
fliftum multo minus Iit eo, quod ab ordinaria acu 
infligitur, neque adeo dolorificum. Ex iisdem ra¬ 
tionibus paulo maiorem acum triquetram commen¬ 
dat pro operatione paracentefeos. Compofita vero 
eft haec acus ex cannula anterius diuifa, et hinc ela¬ 
ftica, et ex plana, deprefla, anciprti ef in vtroque 
latere anterius paululum eleuata acu. Sed fi di¬ 
cendum quod res eft, non intelligimus, quatenus hoc 
inftrumentum ordinariam acum antecedat, nec 
perfuadere nobis poflumus, ab eodem quicquam 
vtile ad hydroceles operationem redundare.
