English citations of singular existential statement

1959, Karl Popper, The Logic of Scientific Discovery, p.83:

A statement of the form ‘There is a so-and-so in the region k’ or ‘Such-and-such an event is occurring in the region k’ may be called a ‘singular existential statement’ or a ‘singular there-is statement’.

1967, Marx W. Wartofsky, “Metaphysics as Heuristic for Science”, in Proceedings of the Boston Colloquium for the philosophy of science:

But, on Popper’s own account, the presumably singular existential statement lacks singularity unless it contains individual concepts, and these, according to Popper’s definition, require proper names (or equivalent signs, e.g. Cartesian coordinates with a specific origin).

1994, Gunnar Andersson, Criticism and the history of science, p.70:

The reason for this second problem is that no singular existential statement can contradict another singular existential statement. There is for example no contradiction between the statements ‘In the time-space-region k there is a P’ and ‘In the time-space-region k there is a non-P’.
