  The paper presents two new results concerning the varieties of Leibnitz
algebras. In the case of prime characteristic p of the base field constructed
example not nilpotent variety of Leibnitz algebras satisfying an Engel
condition order p. In the case of zero characteristic obtained new results
concerning the space of multilinear elements variety of left nilpotent of the
class not more than 3 Leibnitz algebras.
