Accepting those results and comparing them with Helmert’s 
formula, we have the following local disturbances in 
Altona ... 14 | Berlin... 49 | Koenigsberg, E.P. ... 14 
in unities of the fifth place after the point. According to 
Colonel Sterneck are the local disturbances at Hamburg* and 
Berlin respectively + 46 and + 43. 
If we now connect the observations made with the Bessel 
“ Fadenpendel” at Koenigsberg, E.P., by Bessel and Peters with 
those made by Sterneck at Berlin, it follows that the local dis- 
turbance at Koenigsberg, i/Pr., is equal to + 38. 
Consequently we have 
Lohmeier. Vienna System. Difference. 
— 14 + 46 + 60 
— 49 + 43 + 92 
— 14 + 38 + 52 
Mean + 68 
Augmenting all the values of g above given by + 0.00068, we 
obtain as value for local disturbance at Melbourne + 84. 
The measurements of the officers of the Austrian-Hungarian 
navy make that value to be + 65 and + 59, consequently the 
mean value + 62. 
It appears from this that Melbourne, relatively speaking, is 
perhaps somewhat too large, which would correspond to a 
certain extent with the changes in the length of the brass bar as 
suggested by the Standard office at Berlin. 
Taking it absolutely Melbourne with g = 9.79965 would be 
rather too small (ca. 46), for the local disturbance is by that 
+ 0.00016 against + 0.90062, as derived from the observations 
of the officers of the Austrian-Hungarian navy. A definite 
opinion of what is absolutely correct is yet difficult to be given ; 
generally speaking, all absolute determinations with the aid of 
but one pendulum give somewhat too small results. 
As the Vienna system gives about 0.00031 more than Bessel’s 
in Berlin, the observations with Lohmier’s pendulum in Mel- 
bourne seem, absolutely speaking, ony 0.00015 m. smaller than 
Bessel’s in Berlin. 
In concluding this short report on my pendulum observation 
at Melbourne, I cannot but express my regret that the publica- 
tion had to be deferred until so long a time after the period they 
were made and the calculations had been finished. However, 
the discrepancies between the results of the comparisons of the 
standards made it compulsory for me to delay’ the publicéa- 
tion until everything could be cleared up. I have only to add 
that in a few months the paper containing the full observations 
will be placed, I hope, into the hands of the Royal Society of 
Victoria. 
* Observations of the length of the pendulum vibrating seconds at Hamburg (Seewarte) 
have been made by Sterneck in 1892 relatively, by Mahlike in 1894, and quite recently by 
Schumann (Sept., 1899).
