Query: Comment on "The velocity field due to an oscillating plate in an
  Oldroyd-B fluid" by C.C. Hopkins and J.R. de Bruyn [Can. J. Phys. 92, 533
  (2014)]   We correct certain errors and ambiguities in the recent pedagogical article
by Hopkins and de Bruyn. The early-time asymptotics of the solution to the
transient version of Stokes' second problem for an Oldroyd-B fluid in a
half-space is presented, as an Appendix, to complement the late-time
asymptotics given by Hopkins and de Bruyn.
