We construct explicit forms for two non-trivial conservation laws of the quantum non-linear Schrrdinger equation and show that they have the correct quasi-classical limit. For //4 the second quantised form cannot be obtained by normal ordering of the classical conserved quantity H4 ~. We show that t
