Dear all.
In perusing Cauchys "Cours d'analyse" (1821) I have come across the
following (p.35):

"Enfin, lorsqu'un fonction f(x) cesse d'etre continue dans le voisinage
d'une valeur particuliere de la variable x, on dit qu'elle devient
alors discontinue, et qu'il y a pour cette valeur particuliere
solution de continuite."

What puzzles me is the last phrase - "solution de continuite" -
I simply cannot make any sense of it. What can Augustin-Louis mean?
I look forward to hear from those whose knowledge of Cauchy and his
times are more profound than mine.

From Uppsala, deep in the gloom of November.
