 note = {Lie algebroids are by no means natural as an infinitesimal counterpart of groupoids.
In this paper we propose a functorial construction called Nishimura algebroids for an
infinitesimal counterpart of groupoids. Nishimura algebroids, intended for differential
geometry, are of the same vein as Lawvere’s functorial notion of algebraic theory and
Ehresmann’s functorial notion of theory called sketches. We study totally intransitive
Nishimura algebroids in detail. Finally we show that Nishimura algebroids naturally
give rise to Lie algebroids.},
