Others have shown how to do this.
But I'd like to understand _why_ you want to do this.
If it is just to explore the capabilities of the language, that's
fine.
But you should also understand the compiler issues involved. The
reason Ada provides a private part in package specs is to provide
information to the compiler to allow it to generate more efficient
code (not using pointers, for example).
One downside of providing information in the spec is more
recompilation when the private part changes.
