Gallarati studied contact of surfaces in $\mathbb{P}^3$, that is surfaces $V,W \subset \mathbb{P}^3$ such that $V.W = qD$ with $q$ an integer that is at least 2 and $D$ some curve.
I would like to read his results, contained in the 1960 paper "Ricerche sul contatto di superficie algebriche lungo curve". However, this is in Italian and uses older language of algebraic geometry.
Does anyone know a place where to find his results in more modern language, and in English? (French or German will also suffice.)
