Answers to JB's queries on the refraction of light through crystals, and Newton's rings.
Fears that a letter written to him in November may not have reached him. Will send him a copy of his paper of colors. A Philosophical Society has been formed at Cambridge.
Regarding refraction in crystals of apophyllite and quartz.
Was very pleased to receive another of JB's works. Glad to be associated in his revelations concerning molecular and polarization powers. Recall their past meetings and hopes to renew acquaintance in Paris at some future date.
Thanks JB for letter to JH at the Cape. Requests JB to provide introductions for Mr. Stanford, who is making statistical inquiries in France.
