The committee appointed to prepare a minute respecting the 

 death of Professor Henry A. Rowland, would respectfully sub- 

 mit the following report : 



The last half of the nineteenth century is remarkable as a 

 period of great discoveries and advances in the mathematico- 

 physical sciences. It is especially noteworthy for extraordinary 

 progress in the theories of light, electricity, magnetism and ther- 

 modynamics. Soon after 1850 the phenomena of these inti- 

 mately related theories were seen to unify themselves under the 

 recently established doctrine of energy ; and almost every appli- 

 cation of this doctrine in the fields of those theories yielded a 

 rich harvest of results. 



Many distinguished names fall in the list of those who con- 

 tributed to the advances of this period. Naturally, most of the 

 pioneers, like Helmholtz, Joule, Clausius, Henry and Kirchhoff, 

 have passed over to the silent majority. But a singular fatality 

 has attended the most eminent followers of the earlier workers. 

 Thus, within less than a quarter of a century, science has not 

 only lost the distinguished Maxwell and his brilliant disciple 

 Hortz, but is now called upon to deplore the untimely deaths, 

 within a few weeks of one another, of the equally eminent 

 physicists Fitzgerald and Rowland.
