The variable star λ Tauri was observed photoelectrically during the autumn seasons of 1935—1937. In 1935—36 the observations were taken with the Guthnick stellar photocell photometer. In 1937 the new photometer with the thermionic amplifier designed by the author and P. G. Kulikovskv was used. As comparison stars were taken: μ Tauri in 1935 and μ Tauri and ν Tauri in 1936—37. The reduction of all the observations to the v Tauri were made by the aid of the differences of the brightness between μ and ν Tauri derived from the Table I. The mean coefficients of atmospheric extinction (The mean coefficients of atmospheric extinction (p = 0.740 for Abastumani, 1935—36 and p = 0.776 for Mt. Kanobili, 1937) were used. All the observations are listed in Table II. Observations of the dates 2428060; 069; 113-115 and 808 were rejected as they showed great systematic differences with the normal curve (of the order of 0^m.05) Examination oi these anomalous brightness of the variable shows that we have here perhaps the disturbing effect of the third body (as it was suspected by prof. Stebbins) but of quite irregular nature. At the present time we have a too small observational material for stating this surely. The new period of the variable is also derived. Normal points are listed in Table III and drawn on Fig. 1. December, 1937
