ogy, biology, entomology, chemistry and physics. In addition to these he 

 often had a class in Latin and occasionallj^ other branches. Doctor Scott 

 was a man of wonderful strength of body and mind, and haxl a capacity 

 for continued work which was nothing less than astonishing. During the 

 day, after the end of the recitation, he would spend the hours in his 

 laboratory i)reparing for the experiments and recitations for the follow- 

 ing day. Tlie lamp in his study window would often be found burning at 

 night up to 12 and even 1 o'clock, preparing for his sermons on Sunday. 

 He was accustomtd to have in his preparatory work in his lalioratory the 

 assistance of one of his students, and during my time at Hanover I espe- 

 cially remember the enthusiasm with which Mr. INI. L. Amick, now a 

 prominent physician in Cincinnati, displayed in the preparation of the 

 lectures. With a laboratory outfit of the most meager description Dr. 

 Scott was able to give in chemistry a series of experimental lectures which 

 would have done credit to many of the ela)>orate lecture rooms of to-day. 

 There was absolutely no provision for the students' work in the laboratory 

 whereby the fundamental principles of chemistry could be illustrated by 

 appropriate experimental work. Some of these experiments were very 

 ditticult, and at least one of them I have never seen performed in an ex- 

 perimental lecture anyAvhere else in the world, namely, the preparation 

 of tlie highly explosive chloride of nitrogen. The preparation of this 

 compound is one of such danger that it should onlj' be attempted with 

 those most skilled, yet every year for three years I saw Dr. Scott perform 

 this experiment in a most successful manner. The small quantity of the 

 explosive made was placed in a safe place out of doors and exploded by 

 means of a long stick, the tip of which had been dipped in turpentine oil. 

 By reason of this devotion to his profession and the success attending his 

 efforts, he made chemistry, which was at that time one of the dry book 

 studies, a most attractive science. In like manner he would conduct his 

 classes in botany to the neighboring woods and tields and teach them not 

 only the principles of botanical classifications, but the means of identify- 

 ing the various species of plants growing in the vicinity. The hills of the 

 Ohio Iliver, rich in magnificent trilobites and other reminiscences of early 

 geological life afforded a magnificent opportunity for teaching the practi- 

 cal principles of geology as illustrated in those lofty hills and deep ra- 

 vines. Since those days, when I have seen practically all the magnificently 

 equipped lal)oratories of the world, the wonder grows more and more in 

 my mind at the great work which this great man could accomplish with
