Summary:

Enjoying the beautiful scenery, but the weather has not been good. Many thanks for the beautiful translation of Frederick Schiller. Has he added anything to his photographic discoveries? Saw some calographic pictures at Charles Wheatstone's, which improved on the Daguerreotype.

Summary:

Hopes he will look out for the periodical meteors and give him his observations. Has seen some curious falling stars. Is constructing a new anemometer and used it to detect surging gales. Visited a monastery yesterday to see a new instrument for perpetual motion.
