the usual meteorological observations as to tempera-

failing eyesight made it impossible. Little was being 
done in that direction at the time; and his results, 
showing a diurnal, annual, and even cyclic periodicity, 
have acknowledged scientific value. 
The failing eyesight which put a stop to his elec- 
trical observations and also to his medical practice, 
culminated in a total blindness, covering several 
years preceding his death. Fortunately there was 
no lack of willing readers to feed his active mind. 
He passed away peacefully September 23, 1889, with 
wife and children around him.
