Mantell was living in Brighton when the terrible snow storms of Christmas 1836 swept across Europe. The winds created a large crest of snow on the chalk cliffs above South Street in Lewes. On Boxing Day this fell and completely smashed the houses in Boulder Row. He records the event in his diary. The full account can be read in the Sussex County Magazine i (1927) pp70-74, 598
Mantell was Poor Law doctor while in Lewes and would have known and tended to those who lived in the poor houses on Boulder Row.
