More eighteenth-century sanitation

I'm in the mood to look at some more of the sanitation, that the finer classes of the eighteenth century were so good at. I'm hoping it may do something to lift my peculiar mood. I dislike London with a passion, but am fascinated by its social history.
Here are two pictures of Charing Cross, London in the Georgian era. The picture at the top, by Canaletto, dates from around 1750. The better-off woman near the front centre of the painting, is wearing a court mantua. All the people look quite static, as if frozen in time. The people are all clean, well-nourished, well attired and shod. The buildings and road are all beautifully clean. The arrangement seems slightly chaotic; note the cart in the centre and the cartwheel in the road to the right. The chaos, though, is completely contrived. This was a poor area, and would have been teeming with the vermin-infested poor. This was a main thoroughfare, so there would have been shit everywhere from all the passing horses, not to mention the contents of chamber pots hastily thrown out of windows. Canaletto gives his viewer a completely false impression of the character of the area. Only the buildings are accurate.
The second picture dates from around 1810. It shows the pillory at Charing Cross, which was used to punish homosexuals. The Georgian man in the street took a very dim view of homosexuality. Such spectacles drew huge crowds of both genders and all ages, and they treated these 'criminals' with great ferocity. There are accounts of some victims being pilloried to death, or dying of their wounds. This picture gives a better representation of the ordinariness of the area. The buildings haven't been prettified, as in the Canaletto. The local population are presented as they are, rather than in all their finery. The figures have a sense of energy and movement. There is a feeling of impending action. I pity the poor bastards in the pillory. I just wish I could get in there and free them.
Canaletto, though, doesn't want his fine ladies and gentlemen to be worried with irritating little things like cruelty and real life. It would put them off their suppers, wouldn't it?
