GrENTLEMEX, 



F. NANSEX points out in his work on Hydrometers that the 

 employment of hydrometers of total immersion was first sug- 

 gested by Prof. Pisati, and that such instruments were afterwards 

 used by X. Eeggiani and an account of them published in 1890. 



I regret that ignorance prevented me acknowledging their work 

 in my paper on Hydrometers of Total Immersion, published in 

 your Magazine in December 1899. 



I trust that you and your readers will excuse me, on the ground 

 that I am only a chemist and have but little acquaintance with 

 modern work in physics. Tours faithfully, 



Arthur W. Warringtox. 



OBITUARY NOTICE : PROFESSOR FITZGERALD. 



We deeply regret to have to announce the death of Professor 

 Gr. F. FitzGtERALD, which took place on Thursday, the 21st. 



The following paragraph, which appears from a correspondent 

 in the ' Times ' of the 25th, describes so well his amiable 

 character and eminent position among men of science, that it will 

 be appreciated by all Physicists. In him we have lost a most 

 kind and judicious adviser: — 



" Professor FitzGrerald was recognized as being among the foremost- 

 men of his generation in physical science ; the most ungrudgingly 

 helpful to ail other scientific men ; looked up to by his contem- 

 poraries, not merely with respect, but with such genuine affection 

 that this paragraph conveys not merely a news of disaster to the 

 progress of science, but of a personal calamity to great men of 

 science all over the world. He was the indefatigable helper of his 

 students, a number of whom are Fellows of the Royal Society. 

 He was the colleague and inspiring friend of all men who were 

 trying to do good in the world, but more especially of men who 

 were trying to help Irish industry and Irish education of all types. 

 In every department of applied science, in any kind of engineering, 

 his advice was known to be valuable, and he was always ready to 

 give it. His life was devoted to the interests of others in a whole- 

 hearted way. He seemed perfectly unselfish, quite disinclined to 

 have his name honoured, and yet perfectly alive to his own 

 worth. His friends in England have not known that he was very 

 unwell. It was thought advisable to perform an operation ; this 

 was successful, but he had not sufficient strength to recover."
