Mossotti had kept contacts with Pavia university. In 1814 he applied to the
university for a chair as Professor in Algebra and Geometry. The university
was glad to accept him, to the extent that they published his name in the
teachers list
, but the Royal Commission to the Studies denied
him the right of teaching there because he was foreigner. In a letter dated 19 October 1814 (M1), Mossotti
reminded the Government of Lombardy that the objection to his teaching in
Pavia because he was foreigner was not valid as he had already worked in the
Brera Observatoire, which was at the time juridically dependent on Pavia
university. The Government, however, still denied him the job.
The contacts Mossotti had with Pavia university were not limited to job
interest: he still collaborated with Brunacci. In 1814 Mossotti published a
paper Sul moto di un fluido elastico che esce da un vaso in which he tried to
explain some phenomena observed and published by Brunacci. Using some
principles posed by Euler in his note to the Principes d'artillerie by
Robins, Mossotti determined the velocity with which compressed air in a tube
changes direction and the way the pressure changes on the tube walls. He also
extended the theory to containers other than a tube.
