Query: On a Theorem of Schwick   Let D be a domain, n, k be positive integers and n >= K+3. Let F be a family
of functions meromorphic in D. If each f in F satisfies (f^n)^(k) not equal to
1 for z in D, then F is normal family. This result was proved by Schwick. In
this paper we extend this result.
