XV. Observations for ascertaining the length of the Pendulum at 
Madras in the East Indies, latitude 13 0 4' <f',\ N. with the 
conclusions drawn from the same. By John Goldingham, 
Esq. F. R. 1 S'. 
Read January 31, 1822. 
T. he object of the enquiry in this paper has been considered 
at all times one of interest and importance, and is particularly 
so at present, when investigations have been completed in 
Europe, by order of some of the governments there ; such 
as, with reference to their accuracy, had never before been 
made in any quarter of the globe, so far as comes within my 
recollection. I had seen the details of Captain Kater’s ex- 
periments in the Philosophical Transactions, and he also did 
me the favour to send me out a copy of his Paper. The sim- 
plicity and accuracy of the apparatus induced me to write to 
that Gentleman, requesting he would have the goodness to 
order a similar one to be sent to me. This request he not only 
most readily complied with, but made the experiments requi- 
site for enabling me to draw the conclusions ; and thence to 
form the comparison with the results obtained in Europe. 
The apparatus arrived in March, and I immediately set 
about fixing it ; which, notwithstanding the little solid as- 
sistance to be obtained in an operation of this nature from 
workmen in this country, I was enabled to effect in a most 
satisfactory manner ; and I am led to hope, these observa- 
tions will not be deemed unworthy the attention of the 
learned in Europe.
