Soho Square, April 20, 1790.
Madam,—
I return you many thanks for the communication you were so good as to make to me this day of your discovery of a comet. I shall take care to make our astronomical friends acquainted with the obligations they are under to your diligence.
I am always happy to hear from you, but never more so than when you give me an opportunity of expressing my obligations to you for advancing the science you cultivate with so much success.
Dear Madam,
Your faithful servant,
J. Banks.
