Pitman and Yor((20, 21)) recently studied the distributions related to the
ranked excursion heights of a Brownian bridge. In this paper, we study the
asymptotic properties of the ranked heights of Brownian excursions. The hei
ghts of both high and low excursions are characterized by several integral
tests and laws of the iterated logarithm. Our analysis relies on the distri
butions of the ranked excursion heights considered up to some random times.
