Ce{sub 3}In and Ce{sub 3}In{sub 0.9}M{sub 0.1} ({ital M}=Al, Ga, Sn, Ge) reveal the presence of a Kondo anomaly through the occurrence of a negative minimum around 4 K in thermopower studies. Resistivity {rho} studies, on the other hand, reveal a minimum around 20 K and at lower temperatures a resistivity maximum is followed by a sharp drop, which gives evidence for the coherent phase. In this regime a clear change in slope of the {rho} curve is also observed. This could possibly arise from the onset of magnetic ordering developing in this coherent phase.
