Pages 2 & 3 from Morris & Jones's April 1889 Price List - it is interesting to note the brand names which we can still recognise such Carr's, Jacob's, Peak Frean and Huntley & Palmer biscuits. And Spratt's dog biscuits.
We don't use black lead much any more but judging by the range of products on offer it was a staple product in late Victorian times. It was used to clean and polish stoves and cast-iron fireplaces. Blue was a whitening product added to the wash. Citrate of Magnesia was a saline laxative - probably useful after you'd enjoyed Capers, Chutney and Cocoa!
