Quum omnes casus speciales in artt. 29—40 considerati ad casum genera 
lem in artt. 20—28 absolute reducti sint, omnia artificia, per quae in hoc casu 
calculus abbreviatur, qualia in artt. 25, 26, 27 explicavimus, etiam ad illos 
applicari poterunt. Quamobrem non opus erit, huic disquisitioni immorari, cui 
sequens exemplum ad artt. 39, 40 pertinens, finem imponet.
