Gave Hotspur oat cake – This and the two last mornings I have used my umbrella instead of the yard wand to put back my shoulders. I have no further appearance of spitting blood, and wearing my pelisse so all day long must do something to keep me from getting round backed – 

Long letter from Mrs. N[orcliffe] (Langton) – 3 pages, the ends, and under the seal, and the top of the 1st page – Inclosing 2 East Riding guinea notes, and 2 ditto pound ditto (￡4.2.0) from Isabella to pay for the artificial wreath, and the preserved oranges – I must settle this matter, and pay her for the plaid she sent me last year from Edinburgh –

“The plan I mentioned to you about having ice (vide the 1st end of Mrs. N– [Norcliffe]’s letter) was 1st tried at Mr. Duncombe’s at Duncombe Park, his ice-house having failed – You dig a hole in the ground, the shape of an egg, and then with an iron bar make holes in the bottom to receive any water – And at the proper season fill it with snow and ice as an ice-house, and cover it with straw, something like our potato-pies – 3 served Mr. D– [Duncanbe] the summer, and he had one left for another year – I understand it has also been tried at Bishopthorpe – When you come to York, you could see it” – 

Went out at 8 25/60. Read as I walked along, volume 1 Rousseau Confessions from page 65 to 75, and sauntered slowly to and from Hipperholme Turnpike and got back at 9 3/4 – Breakfast at 9 55/60 – Staid downstairs and read aloud the whole of the morning and service – Came up to my own room at 12 1/2 – Wrote the above today – Read forward several pages volume 1 Rosseau Confessions then wrote 1 1/2 page to Mademoiselle de Sans – 

Went downstairs at 5 1/4 – Read aloud from the East Yorkshire Gazette several speeches in the House of Lords on the rejection of the Roman Catholic relief bill – Emancipation bill – Thrown out by a majority of 48 against the 2nd reading – Then read aloud in 1/4 hour sermon 120, volume 3 my uncles collection – Dinner at 6 35/60 – 

In the evening talking to my uncle and aunt –– asked how much land he had. He said Marian would have more acres than I should day works, and then reckoned up six hundred and fifty or sixty of the latter, including woods and the land at Northgate. My aunt said they seemed to have been calculating that he had about eleven hundred a year. He ought to have about this, exclusive of the hundred and fifty he has to pay yearly to my aunt, father – 

Very fine day – Barometer 1 degree above changeable, Fahrenheit 58 1/2º at 10 p.m., at which hour came upstairs – Read Rousseau Confessions volume 1, 1/2 hour then wrote the last 6 lines which took me till 11 20/60 – E [two dots, treating venereal complaint] O [two dots, marking discharge] –
