  In this Comment we argue that Ho$_2$Ti$_2$O$_7$ does not exhibit a transition
to a partially ordered state unlike what is argued in PRL 83, 1854 (1999), that
it exhibits spin ice behavior, and that the experimental specific heat data by
Siddharthan et al. can be accounted for in terms of a "dipolar spin ice" model
by including an expected contibution from the nuclear Ho spins to the
appropriate long-range treatment of the dipole-dipole interactions.
