economy of time, as to afford large opportunity for profound and con- 

 centrated intellectual industry. 



So far as we know, Professor Diman has published little except 

 occasional sermons, lectures, and addresses, which, however, are not 

 fugitive or ephemeral, except in form. He must have left full courses 

 of lectures and other writings, which will be gladly welcomed by his 

 many friends and admirers, and cannot but extend his reputation in 

 time and space far beyond the limits prescribed to it by his own mod- 

 esty and reticence. 



Professor Diman was respected, esteemed, and beloved by all who 

 knew him. In the city of his residence he was well known as the 

 fiiend of the poor, the wise counsellor and ready helper in every good 

 work, the pioneer in every movement for the insti-uction, elevationj 

 and improvement of the community. In all the relations of life, and 

 in his whole social intercourse, he had the manners, bore the character, 

 and breathed the spirit, of the " highest style of man," — the Christian 

 gentleman.

 years. He was born near Columbia, Pa., in 1812, and graduated at 

 Dickinson College in 1830. In 1836 he was connected with the 

 Geological Survey of New Jersey, and the following year with that of 

 Pennsylvania. He was Professor of Natural History in the Univer-

 Among these are his work on the " Freshwater Mollusca of the United 

 States," his " Zoological Contributions," and a paper on the Coleoptera 

 Longicornia of the United States. Later he devoted himself espe- 

 cially to philological studies, phonetics, and orthography. His " Analytic 

 Orthography " obtained for him in England the Trevelyan prize in 

 1858. He paid much attention to the Indian languages of North
