Dear Sir
Will you ask the V.P. of the Society & Mr. Miller at whose house we were at the other night, and any one else you may think would be useful to come to my house some night soon — as soon as you please, when the night is likely to be good for star gazing — and to come himself of course — for the purpose of trying and testing my telescope.
And be good enough if the gentlemen are able to come to let me by 4 PM of the day + hour they will come, and I shall be very glad to see you all.
