experimentation (eksper"i men tash on)

[= F. expérim ent at i on; as experiment, v., + -ation.] The act or practice of making experiments; the proce of experimenting. Thus far the advantage of experimentation over simple observation is universally recognized: all are aware that it enables us to obtain innumerable combinations of circumstances which are not to be found in nature, and so add to nature's experiments a multitude of experiments of our own. J. S. Mill, Logic, III. vii. § 3.
