In replacing the clarinet parts of the typeset version, the original typesetter incorrectly copied the part, in bar 244 in octaves it should read D, C# C natural, instead of D C double sharp C sharp as written in the part.
These parts have been extracted from the typeset score, without any attention to the location of page turns. It is still possible to use them, but by keeping the sheets in a loose stack, shifting them aside during bars of rest.
