In response to my posts about early IPA, Gary Gillman pointed me at some analyses made by the Lancet in 1862 (https://books.google.ca/books?id=HYVMAQAAMAAJ&pg=PA631&dq=1862+Lancet+pale+ale+salt&hl=en&sa=X&redir_esc=y#v=onepage&q=1862%20Lancet%20pale%20ale%20salt&f=false).They show some surprisingly strong examples. But there's some room for interpretation, as they don't include a full set of numbers - OG, FG and ABV, rate of attenuation. And it's not clear (at least to me) what one of the columns is.
It's headed "Absolute Alcohol" with a note saying "Specific gravity 793.9". Does it mean ABV or ABW? I'm not sure myself. Any help would be welcome. Here's what the table looks like:

To try to work out which it is, I've filled in the missing numbers. The first time assuming ABV:

On that basis, all the Bass Pale Ales look to have too low an OG. Other analyses show it consistently around 1065ยบ. But the FGs also also look way too high.
Assuming ABW makes the Bass OGs look more as expected. But a couple of the Pale Ales look ridiculously strong, around 10% ABV. Way higher than any others I've seen. It also gives Fowlers 12-Guinea Ale an OG of 1159. Though, knowing the ridiculous gravities Scottish beers sometimes had, that doesn't seem impossible.
