Mr. Goldingham’s observations for ascertaining 
again appeared, both which the Bramin put down ; the 
mean of these I took as the true time of the coincidence, and 
registered it accordingly. These times I found could be ac- 
curately noted ; and it is probable the mean of the two obser- 
vations is generally correct to less than half a second. In 
this manner the times of the coincidences were observed. The 
thermometer often varying a good deal in a short time, I 
thought it right to take its height three times, at the third 
observation of each set, as well as the first and fifth. The 
barometer was observed at the end of each set, as well as at 
the beginning; and also the hygrometer, as mentioned above, 
at the beginning of the observations, and likewise at the end 
of those of each day ; being desirous of seeing how much the 
atmosphere had changed in dryness, as well as in heat and 
weight; not that this was material, but it is satisfactory to 
know what change there actually was in the atmosphere 
during the time the observations were making. I now 
proceed to detail the observations. 
Every observation taken is here given. As although in this 
as in similar cases, one feels better pleased with some obser- 
vations than with others, yet I do not recollect more than 
two of these observations, which I felt dissatisfied with at the 
time, and that not in a sufficient degree to induce me to think 
of rejecting them. 
The results, I trust, will prove how unnecessary it would 
have been to have rejected any of the observations.
