Being Christmas day my wife and I both at church in the morning, the text Hebrews 9:26: “but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.” My wife and I stayed the communion; gave, each of us, 6d. At home all day. On reading Derham’s notes on Boyle’s lectures I find he says that Mr Boyle demonstrates that so slender a wire may be drawn from gold that from one ounce of gold a wire may be drawn 777,600 feet in length or 155 miles and a half [!]. In the evening Thomas Davy here and supped with us and stayed till 11 o’clock but drank nothing, only 1 pint of mild beer. We read Smart’s poems on immensity, conscience and power.
