Query: A mass relation for neutrinos   A generalization of the well-known Georgi-Jarlskog relation m_{\mu}/m_{\tau}
= 3 (m_s/m_b) to neutrinos is found in the context of SO(10). This new relation
is m_{\nu_\mu}/m_{\nu_\tau} = 16 (m_c/m_t), which is consistent with present
data, assuming the small-angle MSW solution to the solar neutrino problem.
