The [ital c]-axis resistivity of Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub [ital x]] single crystals shows a magnetic-field-dependent peak below the zero-field [ital T][sub [ital c]]. We find good agreement with the temperature and field dependence of the peak, by modeling the [ital c]-axis conduction as a series stack of Josephson tunnel junctions. For intermediate values of the Josephson coupling, we predict such a peak and verify it by measurements on discreet, thin-film Josephson junctions. The exaggerated effects in Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub [ital x]] result from its unusually large energy gap and fluctuations.
