20th February 1742/3
Spent with Mr Nelson at Highgate 8d

The only contemporary picture of Highgate that I can find is this one
Thomas must, surely, have seen such a prominent building?

A mere 5 miles each way which is short for Thomas on a Sunday (it was a Sunday)

21st Feb
Went to see the Merry Wives of Windsor with Orpheus & Uridicey. The Serpent come on the Stage the Thing was their 2/6

Orpheus & Eurydice was an opera produced by John Rich at Covent Garden. The Serpent was mechanical and the talk of London according to the Scots Magazine of 1740. Its inventor, Sam Hoole went bankrupt when left with a stock of serpent toys (merchandising, it seems, is nothing new).

7th September 1742 Bror left London I and Mr Hall went with him as farr as High Gate & spt 6d

This is a 4 mile walk which would be very different from today. It would only be built up as far as the end of Gray's Inn Lane(now Road). They would have gone almost past site of the Foundling Hospital. The Foundation Stone for that building was laid in the same month.
