Summary:
While in Switzerland requested his wife to send to JH a little tract on Count de S. Robert's hypsometrical investigations. Found that Robert's formulae worked correctly for ordinary European heights. Realizes that JH demolished Robert's theories, but Robert also showed observations on P. S. Laplace's theories.
