special and powerful ettieaey; their adversaries ridicule the idea. The experiments of Crookes have shown that radiant matter possesses new properties. An enthnsiastie admirer of Hahnemann eites this fact as a strong eonfirlnation (if the infinitesimal theory.--Les Mio)Mes, April 14~ 1883. C. Ill Ill I ()BITUARY.--JOIIN C. TRAITTWINE.
John Cresson Trautwine, tile eminent civil engineer, whose death occurred on the fimrteenth of September, 1883, at his home ill Philadelphla, was ttle ehtest child of' the late William Trautwln% Sr., and Sarah Wilkinson, his wit'< Ire was born in this city March 30th, 1810, and his early ehildhood was passed at his tkther's house on Water street, near Market, adjoining that of the late Stephen Girard.
While very young lie acquired a marked fondness %r the natural seienees; particularly physics and mineralogy.
Iu all probability this inclination was awakened by his t~ther's @lends, one of whom~ the late Joseph Loughead, Sr., at that time a prominent teacher, took much interest in the boy and eneouraged him in various ways. When about seven yearn old, he one day strolled away from dm house and w,'ks so long absent that his ihther began a seareh for him which ended by his discovery, fhst asleep, on a stall in the old Market street market sheds, with his I)oekets so stuffed with Inineral specimens from tile adjacent country that he eould walk but with difficulty. Soon after this he was placed under the charge of tile late James I ). Espy, who may be said to have been the father of the system of organized meteo-rologieaI observations and under whom he studied natural philosophy and Inathematles. At an early age he learned to draw and paint with f.teility and quickly became an adept in water coloring, t~is rough note-book eontains exquisitely painted little sketches of bridges, parts of t)uihlings and other subjects, on the margin of pages crowded with hastily written memoran(la.
In 1828, when eighteen years old, he entered the office of the late William Strickland, at that time located on the south side ot " Areh street, above Sixtt b opposite the theatre then being built. Mr. Striekland was the most f/romimel~t civil engineer and architect in this part of the United States and young Trautwln% while with hint, was engaged on some of" tile prindpal engineering works of that day.
Soon after entering ~{r. Striekland's once, in 1828, he prepared and mtbmitted a competitive design tbr the Penn Township Bmtk, opposite ~ov., lSSa. ]
