156 MEMOIR OF THE LATE PROF. E. HODGKINSON, F.R.S. 



that they might be more accessible to engineers than they 

 now are in the volumes of learned societies. 



Mr. Hodgkinson^s religious emotions were silent^ de- 

 votional in the highest sense — not sectarian ; they were 

 strictly confined to the channel between his Maker and his 

 own soul. And in this way they were purified by the 

 truth from heaven^ bearing the precious fruit of meekness, 

 charity, and implicit confidence in Him who is all and 

 sustains all. His religion was the arbiter of his life, the 

 judge of the many and important obligations between God, 

 his fellowman, and himself. His end was peaceful, and he 

 has left a name marked by strict integrity, which will be 

 well remembered in the walks of science for ages yet to 

 come. 



Let us now pass on to notice more in detail the works 

 of Mr. Hodgkinson, which have raised him to a good degree 

 amongst his cotemporaries, and will also be the introduc- 

 tion to future thinkers in the same field of labour which he 

 successfully cultivated.

The objects aimed at in this paper are, as stated by the 

 author, to unite, in a general formula, the commonly re- 

 ceived theories, in which all the fibres are conceived to be 

 in a state of tension ; and next, to adapt the investigation 

 to the more general case, where part of the fibres are ex- 

 tended and part compressed, and to seek experimentally 

 for the laws that regulate both the extensions and com- 

 pressions. The manner in which these objects have been 

 sought and developed is a model, worthy of every com- 

 mendation, of clear, sound, geometrical reasoning and re- 

 fined artifice. And the data necessary to give practical 

 efi'ect to the various analytical formulae have been obtained 

 from experiments, than which none have been recorded with
