Letter from William Huggins, 90 Upper Tulse Hills, to the Royal Society 'Dear Sir, I paid Harrison's bill. I enclose their receipt. The bill was sent to me from the [Royal Society]. I sent a P.O. form here, but as the P.O. was simply enclosed with the bill, Harrison & Sons, may have thought it came from [?]. Yours very truly, William Huggins.' 25 April 1906
