FELIX, a devoted Swiss missionary, was born at Geneva on the 8th of October 1798. He received his early education chiefly from his widowed mother, who was distinguished for her piety; and occasionally had the benefit of a lesson from some kind pastor of his native canton. The favourite authors of his boyish years were Plutarch and Rousseau; and he took great interest in the study of natural history and mathematics. He was placed at an early age with a florist-gardener in the environs of Geneva, and at the age of seventeen entered the army, that he might no longer be a burden to his poor mother. Here his patient industry and excellent character soon raised him to the rank of sergeant; but his earnest, thoughtful nature becoming greatly impressed with the truths of religion, he was induced in 1819 to exchange the life of a soldier in the garrison of Geneva for that of a Protestant missionary in the wild glens of the High Alps. The first years of his missionary life were spent as a proposant or catechist in the cantons of Geneva, Neuchâtel, Berne, and the Pays de Vaud. In 1821 he turned his attention to the destitute district of Grenoble in France, and subsequently to that of Mens in Isère, with the hope of making "recruits," as he was wont to phrase it. He went to England in April 1823, and after obtaining clerical ordination from the Independents there, he returned to the scene of his former labours at Mens. A short time afterwards, we find him among the High Alps, pursuing his noble undertaking with great courage and zeal among the descendants of the Vaudois, in the wild picturesque valleys of Queyras and Freysinieres. Here he dedicated temples, organized schools, and laboured incessantly, "by day and night, through wind, snow, and ice," among those lonely glens and savage mountains, until he broke his health. The baths of Plombières were visited without any permanent effect, and he returned to native Geneva only to die. Small companies of the poor people of the distant Alpine valleys made long journeys on foot through the snow to see their dying pastor; but the spring of 1829 put an end to his sufferings, and sent these devoted ones back to their native wilds in tears.
