  We use the Gauss decomposition of the generator matrix in the $R$-matrix
presentation of the Yangian for the orthosymplectic Lie superalgebra ${\frak
osp}_{N|2m}$ to produce its Drinfeld-type presentation. The results rely on a
super-version of the embedding theorem which allows one to identify a
subalgebra in the $R$-matrix presentation which is isomorphic to the Yangian
associated with ${\frak osp}_{N|2m-2}$.
