ogy, biology, entomology, chomistry and physios. In addition to these he 

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

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

 for continued work whicli was notliing less than astonishing. During the 

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

 lal)oratory preparing for the experiments and recitations for the follow- 

 ing day. The lamp in his study window would often be found bvu'uing at 

 iiiglit u]) to 12 and even 1 o'clwclc. preparing for his sermons on Sunday, 

 lie was acH'Ustomcd to liave in his pre]!aratory work in his laboratory the 

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

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

 prominent physician in Cincinnati, displayed in the preparation of the 

 kctures. Witli 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 elaborate lecture rooms of to-day. 

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

 wliereby the fundamental principles of cliemistry could be illustrated by 

 appropriate experimental work. Some of these experiments were very 

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

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

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

 compound is one of such danger that it should only 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 

 e.xplosive made was placed in a safe place out of doors and exploded by 

 means of a long stick, the tip of wliich liad Ijeen dipped in turpentine oil. 

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

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

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

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

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

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

 Ohio River, 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 laboratories of the world, the wonder grows more and more in 

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