Again, there are some surprisingly weak examples. The lowest OG is just under 1045º. To put that into context, William Younger's Table Beer from around the same period wasn't much weaker at 1036º. And Whitbread's X Ale, their weakest Mild, was 1074º in 1844, considerably stronger than any of the IPAs in the table. Though, due to a lower degree of attenuation, it was only around 6% ABV.
Speaking of attenuation, as with the export IPAs, it's extremely high, averaging not far short of 90%. That's extremely high for the first half of the 19th century. Only one example is under 80%, and only just. Somewhat surprisingly, the the draught versi0ons aren't significantly less well attenuated than the bottled ones.
The average OG, on the other hand, is considerably lower than in the export versions. Which was1059.8º for the India-bound versions and 1064.6º for exports to other destinations.
