Summary:
Pleased to hear of the good health of JH and family. Everyone hopes JH will make new discoveries in the physiological and anatomical fields as a result of his observations. Etna's crater is slowly changing. A fireball has been observed; also Halley's Comet as correctly predicted by Niccolo Cacciatore.
