Assures him no discourtesy was meant in not acknowledging his offer, and that it was overlooked accidentally. The Royal Society receives many such letters and it is not in their remit to give their opinion on them.|
The Royal Society has no such apparatus he refers to, not even in its museum at South Kensington. There are no opportunities for conducting scientific experiments except in illustration of papers being read at weekly meetings.
