Your memorandum of the 9th inst [instant] was laid before our Soiree Committee at their meeting yesterday. While thanking you for your kindness in offering to exhibit, they think the instruments named in your memorandum are rather too technical for a Ladies' Conversazione. Perhaps next year at our May Soiree you may have something similar which you would be willing to show.
I am, yours truly,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
