v PROFESSOR AT OWENS COLLEGE 107 



latter was a most accurate and careful worker, and 

 took infinite pains with the students. He was a 

 man with an original mind and had an extensive 

 knowledge of his science, which won for him later 

 a high position among chemists. When he accepted 

 the college demonstratorship he advised me to ask 

 a young German friend of his, Schorlemmer, to 

 take his place as my private assistant, and, accepting 

 my invitation, Schorlemmer came to Manchester, and 

 continued much of the work which Dittmar and I had 

 begun. I soon found that Schorlemmer was a man of 

 great ability. He remained with me for thirty years ; 

 indeed, to the end of his life. Throughout that period 

 we were much attached to each other ; indeed, I do not 

 think during the whole of that time we ever had a dis- 

 agreement We worked on the boiling-point of acids, 

 a subject which has proved to be of considerable 

 theoretical importance. 



Schorlemmer was born at Darmstadt, the birth- 

 place of many distinguished chemists. He came of 

 poor parents, but by economy and hard work he 

 secured an education which enabled him to attain a 

 high position in the ranks of Science. He was neither 

 an eloquent lecturer nor a neat manipulator, but his 

 lectures were as full of sound matter as an egg is full 

 of meat, and his experimental investigations were 

 fruitful of good results. As an historian of the science, 

 Schorlemmer was only second to Kopp, for his know- 

 ledge of both branches of chemistry was wide and 

 accurate, whilst his sustained power of work, whether 

 literary or experimental, was truly Teutonic. 



His researches on the hydrocarbons rank as 

 chemical classics, and his successful controversy with 

 Frankland as to the constitution of the so-called 

 alcohol radicals and of their hydrides forms an interest-
