Laugier determined the exact latitude of the Paris observatory, correcting previous errors. He published a catalogue of fifty-three nebulae, and another of the declination of 140 stars, and contributed astronomical papers to the Connaissance du Temps. He was long associated with Arago in researches on terrestrial physics, and was for some years president of the Academy of Sciences.Work
