Rising Damp to his belief in some aspect of Philip's lore: for example, the 'love wood' which fails to excite Miss Jones (in the 'Charisma' episode, first broadcast 1974). Philip is an intelligent, educated man (more so than the moderately educated Alan and Miss Jones), he is sophisticated and suave; this makes Rigsby suspicious of him, particularly as Miss Jones openly fancies him. Philip does not reciprocate Miss Jones's romantic interest. Croydon was not revealed to be the true birthplace of Philip until the film version of "Rising Damp" (1980).

Damp (structural) D Hoff in their paper "Rising damp: capillary rise dynamics in walls". The analysis is based on experimentally well established properties of porous building materials and the physics of evaporation from building surfaces. Hall and Hoff show that the model can be used to predict the height to which damp will rise in a wall. The height of rise depends on the wall thickness, the sorptivity of the wall structure and the rate of evaporation. Further work has confirmed experimentally the importance of mortar properties in determining the height to which damp will rise in walls. "BRE Digest" 245 lists
