- In the original version of this paper, we assume a theory $T$ that the logic $\mathbb L_{κ, \aleph_{0}}$ is categorical in a cardinal $λ> κ$, and $κ$ is a measurable cardinal. There we prove that the class of model of $T$ of cardinality $<λ$ (but $\geq |T|+κ$) has the amalgamation property; this is a step toward understanding the character of such classes of models. In this revised version we replaced the class of models of $T$ by $\mathfrak k$, an AEC (abstract elementary class) which has LS-number ${<} \, κ,$ or at least which behave nicely for ultrapowers by $D$, a normal ultra-filter on $κ$. Presently sub-section \S1A deals with $T \subseteq \mathbb L_{κ^{+}, \aleph_{0}}$ (and so does a large part of the introduction and little in the rest of \S1), but otherwise, all is done in the context of AEC.
