Union Infirmary, terms on registers

[Mildred298]

Hi as part of my research I've found the following documents.
Does anyone know the meaning of the abbreviations in the Observations columns. And, was Champion Hill a place for people with poor mental health?

The abbreviations in the Observations column are the individual parishes within the St Saviour's Union to which each pauper was chargeable, e.g.
N - Newington
SG - St George (Southwark)
SS - St Saviour (Southwark).

Champion Hill (in East Dulwich, opened c. 1887) was the Infirmary site for the whole St Saviour's Union, nothing to do with mental health.

Thanks for your help, much appreciated. That's obvious now you say it.
My family features a lot in those parishes and others around London.
My Mum, even in 1921, was in the Wandsworth Union.
I thought they may be a level or type of ill health.
