CELEBRATION OF THE FIVE HUNDREDTH ANNIVERSARY OF THE UNIVERSITY OF
HEIDELBERG, AUGUST, 1886.
The wave of pleasure and enjoyment which flooded everything has
passed. Heidelberg, usually so quiet, assumed the role of a city of
the world, and all was bustle and excitement in the streets, which
were hung with flags and other decorations. The trains constantly
brought new accessions to the crowd, and gayety and mirth reigned
supreme.
The dedication of the renovated _Aula_ of the University served as a
prelude to the festivities of the week. On this occasion a splendid
flag, embroidered by order of the wives of the faculty of the Academy,
an equally costly cover for the scepter, and a silver inkstand were
added to the treasures of the University. Conspicuous among the
numerous presents received were a richly carved set of furniture--the
gift of former students from Switzerland--and all the publications of
certain book dealers.
