slung on to a rigid bamboo by means of
four rubber bands about 1 wide and i
thick. This was earned all the way
between two coolies except from Kut Saiyto
Ali to Khafajiyeh and from Bisaitin to
Tama’ni where it was placed in a bellam.
It was soon evident, however, by the daily
comparisons of the^ Hack watch with the
chronometer (marginally noted) that both

Unrel i a beg to submit that in my opinion the ^uddln“mit
chronometer and Hack watch was as much due to the great ^udden^ ^

the tent the temperature rose to over no , a difference 43 care was
and this recurring for nine days in succession. The greatest possibl .
taken, either Overseer Feroz Bakht or myself riding by the coolies who carried it
all the way. The observations for Lat. at Khafajiyeh taken by
house by meaning sets of *antares both east and west of the Meridian resulted
m Latitude 31° 33' 48 46" N. The Longitude used for reckoning the hour
angle was 48° 10' 45" E.
The observations for Latitude at Bisaitin (centre of village) taken by
meaning sets of *antares both east and west of meridian w T ith Pole star resu t-
ed in Latitude 31° 43' 29'i" N. The longitude used for reckoning the hour
angle was 48° o' E.
The observations for latitude at Hawizeh (eastern end of town) taken by
meaning sets of antares both east and west of meridian with the Pole star
resulted in Latitude 34 0 28' 2 , 2" N.
Equal altitudes of the sun’s upper and lower limb 4 sets, were taken and a
meridian distance was run thus from Hawizeh to Nasiri, the interval being 2
days. Allowing the old rate of ri67 losing daily, the results place Hawizeh
34' 8’7" west of Nasiri which result tallied so closely with the result of Lieuten
ant Wilson’s planetable survey that in my opinion it may be assumed that the
chronometer (by which the meridian distance was run) kept good time during
these two days, and the difference shewn during these two days between the
comparisons was result of the Hack watch going badly and not the chronometer.

On return to Nasiri on July and my observations resulted in shewing the
chronometer to have lost 3m. 10*96 secs, over and above its accumulated error
and the Hack watch to have gained 35’66 secs, over its accumulated error.
