I'll be happy to do so when I get it, but in the meantime there's a picture of the front of the dust jacket here:

Well, perhaps, but in this case I think Tolkien is dead on. The Dunsany story, e.g., (which is short and freely available on the web) really is _awful_, and its final paragraph truly execrable.

Here's what I've got with a bit of work; I think I can get more in time.

========

Jirel of Joiry. Does create an atmosphere
and [?the] sinister 'corrupt' household of Alaric was
eerie and credible. But I never [sic] find phantasmal
struggles such as that of Jirel with 'Undead' Andred
quite unconvincing — especially when the victims escape!

Dunsany at his worst. Trying so hard for
the shudder. But not for a moment making the
tale 'credible' enough to {pro} make a background for
a strong [?e...]. And the ending lamentable — in
fact [?insulting]. In a world in which a Thangobrind
could even begin to be (let alone Hlo-hlo or [?all the rest])
early 19th century Riviera [?...] is surely utterly
impossible — or vice versa. And what is meant
by selling his daughter's soul.

Cappen Varra. Nomenclature v[ery] bad
Let us have genuine Scandanavian/Norse "bar-
barians" or something invented.

The Athammaus monster wholly unbelievable
[?…] disgusting [?... ... …]. There are lots
of ways of being [?... as] nastily, without all this
[?tooraloo] of nonsense.

Most of these things are overheated & exaggerated
([?...] bigger or [?would be] bigger, [?'...'] is
[?...] than the {ends} purposes warrant)
Also obviously over or ill-written.

Jirel of Joiry 140 - 146 is good but
needs a [?deft] story (and [?explication]) to [?...]
[?valid]. Dunsany's is one of his worst
That final ghastly paragraph!

Glad to help. Please also include a copy of the table of contents of the volume it accompanies, as these notes are Tolkien's comments in review of the volume and cites some titles and authors.
