Perhaps it is an extremely small sphere in a certain test-tube.

The storm is a gale situated in mid-Atlantic with a certain latitude and longitude, and the cook is in the kitchen.

I will call this special form of ingression the 'relation of situation'; also, by a double use of the word 'situation,' I will call the event in which an object is situated 'the situation of the object.' Thus a situation is an event which is a relatum in the relation of situation.

Now our first impression is that at last we have come to the simple plain fact of where the object really is; and that the vaguer relation which I call ingression should not be muddled up with the relation of situation, as if including it as a particular case.

It seems so obvious that any object is in such and such a position, and that it is influencing other events in a totally different sense.
