WISLIZENUS—-ATMOSPHERIC ELECTRICITY. ils 
Additional Remarks on AvmospHEric Hiecrriciry. 
By A..Wisuizenvs, M.D. 
The delay in the publication of this volume enables me to 
add to my observations of atmospheric electricity in 1861, 
the result of my observations in 1862. ‘he latter observa- 
tions have been made in the same manner and by means of 
the same fine glass thread, which, after many thousand tor- 
sions, proves as good as ever. I present herewith in tabular 
form the general result of my observations in 1861 and 1862. 
1. Monthly mean of Positive Atmospheric Electricity in 1861 and 
1862, at Si. Louts, Mo., based upon daily observations at 6, 9, 12, 
@, 0 and 9 o'clock, from morning till night. :

* This table of 1961 differs in some decimals from that published on page 66 and in Dia- 
gram No.1. Having discovered some errors, i calculated all my observations once more, 
and give now the present as the correeted table. 
Il. Monthly mean of Temperature and of Relative Humidity in 
1861 and 1862, at Si. Louis, Mo., based upon daily observations,
