Not P but Moby-Dick (74)

[Mike Jing]

>From Chapter 94:

There is another substance, and a very singular one, which turns up in the
course of this business, but which I feel it to be very puzzling adequately
to describe. It is called slobgollion; an appellation original with the
whalemen, and even so is the nature of the substance.

What does "even so" refer to here? Does it mean the nature of the substance
is also very puzzling, or is it something else?
