We have enlarged the sample of stars in the planet search at Lick Observatory. Doppler measurements of 82 new stars observed at Lick Observatory, with additional velocities from Keck Observatory, have revealed two new planet candidates. The G3 V/IV star, HD 195019, exhibits Keplerian velocity variations with a period of 18.27 days, an orbital eccentricity of 0.03±0.03, and Msini=3.51 M_JUP. Based on a measurement of Ca II H and K emission, this star is chromospherically inactive. We estimate the metallicity of HD 195019 to be approximately solar from ubvy photometry. The second planet candidate was detected around HD 217107, a G7 V star. This star exhibits a 7.12 day Keplerian period with eccentricity 0.14±0.05 and Msini=1.27 M_JUP. HD 217107 is also chromospherically inactive. The photometric metallicity is found to be [FeMH]=+0.29±0.1 dex. Given the relatively short orbital period, the absence of tidal spin-up in HD 217107 provides a theoretical constraint on the upper limit of the companion mass of less than 11 M_JUP.
