  For the first two equations of the Volterra lattice hierarchy and the first
two equations of its non-autonomous (non-isospectral) extension, we present
Riccati systems for functions c_j(t), j=0,1,..., such that an expression in
terms of Hankel determinants built from them solves these equations on the
right half of the lattice. This actually achieves a complete linearization of
these equations of the extended Volterra lattice hierarchy.
