Matthiesseu's investigations into the electric conductivity of copper were of great importance from the rapid expansion 



of telegraphy. 



* He showed that the discrepancies of previous observations and the low conductivity of certain samples of copper 



supposed to be pure were due to the presence of minute quantities of other elements.'!). N. B.

' Matthiessen's researches show remarkable acuteness, experimental skill, and conscientiousness, together with a 

 distinct power of generalisation.' D. N. B. 



He received the Royal Society's gold medal for his researches on the electric and other physical and chemical 

 properties of metals and their alloys.
