The Death Cults of prehistoric Malta.

A crystal controlled overtone oscillator having a feedback circuit comprising a series connected inductance-capacitance arm having the values of the inductance and capacitance chosen to provide a net inductive reactance at the desired overtone and a net capacitive reactance at lower overtones, and a shunt inductance-capacitance arm that is resonant at the desired overtone. A broadband neutralization network is employed to neutralize the static shunt capacitance of the crystal and to provide the shunt inductance-capacitance arm.
