We use combinations of 10 small-scale cosmic microwave background anisotropy data sets from the UCSB South Pole 1994, ARGO, MAX 4 and 5, White Dish, and SuZIE experiments to constrain cosmogonies. We consider open and spatially flat-Λ cold dark matter cosmogonies with nonrelativistic mass density parameter Ω₀ in the range 0.1-1, baryonic mass density parameter Ω_B in the range 0.005-0.029 h^–2, and age of the universe t₀ in the range 10-20 Gyr. Marginalizing over all parameters but Ω₀, the combined data favor a Ω₀≃1 (1) open (flat-Λ) model. Excluding the smallest angular scale SuZIE data, an Ω₀≃0.3 (1) open (flat-Λ) model is favored. Considering only multifrequency data with error bars consistent with sample variance and noise considerations, i.e., the South Pole 1994 Ka band, the MAX 4 ι Draconis, and the MAX 5 HR5127 data, an Ω₀≃0.1 (1) open (flat-Λ) model is favored. For both open and flat-Λ models and for all three combinations of data sets, after marginalizing over all other parameters, a lower Ω_B_h² (∼0.005) or younger (t₀∼10 Gyr) universe is favored. However, the data do not rule out other values of Ω₀ in the flat-Λ model and other values of Ω_Bh² in both models. At 2 σ confidence, model normalizations deduced from the small-scale data are consistent with those derived from the Differential Microwave Radiometer data. We emphasize that since we consider only a small number of data sets, these results are tentative.
