An Cross-Species Switches

Cross-Species Switches were a type of Transfiguration that was caused when transforming spells were modified in certain ways. They were presumably a type of Switching Spell that changed certain aspects of different species and may therefore have been Trans-Species Transformation.
==History==
During the 1991–1992 school year, the following problem about Cross-Species Switches could be seen on the blackboard in the Transfiguration Classroom:
:If bodyweight is A, viscousness is V, intended transformation is T, wand power is W and concentration is C, and assuming T=(W×C)÷(V×A)×Z, then what does Z equal?
==Nature==
It was easier to preform Cross-Species Switches when the creatures were similar in appearance or structure.
