"Myself" is a compound personal pronoun. In the sentences you provided, "myself" would be replaced with "I." A common misuse of the word "myself" is in a sentence such as "The three members at this point are expected to be John Doe, Jane Doe, and myself." This is incorrect. The sentence should read "The three members at this point are expected to be John Doe, Jane Doe, and me."
Can we use " Myself " in the sentence like this...........
Myself, John, a chemistry professor ......................
OR its more correct to use
I, John, a chemestry professor..............
