THE BEGINNING OF HIS WORK AS PROFESSOR. 131 



so that his instructions were not etymologic-ally lectures 

 or readings, but free, fluent talks, prepared for evidently 

 with care, and delivered in a style, as some would say, 

 rather ornate for a strictly scientific discourse. Severe and 

 sensitive critics might go so far as to say that there was in 

 his style of lecturing a slight affectation of the exquisite ; 

 while others would say " nay, but a very natural elegance." 



In his demonstrative experiments he was always success 

 ful, and in all his manipulations there was uniformly a 

 grace and nicety that was pleasant to those of us whose

His elocution was distinct, sometimes rather too rapid for

 pass. He was as a lecturer a true prophet, showing a full 

 knowledge of his subject, and because of that knowledge 

 able to predict the phenomena that would result from stated 

 conditions. 



Mr. Silliman's chemical lectures in Boston were emi 

 nently successful. In regard to his manner of lecturing 

 when I just compared it with what it was when I first heard 

 him, if I speak as I have done, of its almost perfect iden 

 tity, thereby implying that he had not improved much be 

 tween those periods, you, sir, ougjht not to be greatly
