It is shown that a sensitive search for neutrino oscillations involving more flavors than just nu/sub e/ and nu/sub ..mu../ is provided by measurement of the ratio of the total interaction rates of upward- and downward-going cosmic-ray neutrinos within a massive (approx. 10 kiloton) detector. Assuming mixing between all pairs of nu/sub e/, nu/sub ..mu../ and nu/sub tau/, the experiment is capable of observing time-averaging probabilities < P/sub e tau/>/sub t/ of magnitude set by mixing strengths corresponding to, e.g., the d- to s-quark mixing strength, and of reaching the limit ..delta..m/sub ij//sup 2/ identical with vertical bar m/sub i//sup 2/-m/sub j//sup 2/ vertical bar approx. = 10/sup -4/ eV/sup 2/, where m/sub i/, m/sub j/ are neutrino mass eigenstates, and P/sub e tau/ and p/sub ..mu.. tau/ are the probabilities for nu/sub e/ and nu/sub ..mu../, respectively, to oscillate into nu/sub tau/ after traversing a distance L approx. = diameter of the earth.
