     Habes igitur (Lector benevole) in hoc libellо, doctrinam constructionis Logarithmorum (quos híc numeros artificiales appellat; hunc enim tractatum, ante inventam Logarithmorum vocem, apud se pro aliquot annos conscriptum habuerat) copiosissime explicatam; in qua eorum natura, symptomata, ас variae ad naturales eorum numeros habitudines perspicue demonstrantur.
