Traverses of the routes followed were made by pocket compass
checked by astronomical observations taken with the sextant and artificial
horizon have enabled the routes to be laid down with very fair accuracy. A map
on a scale of 8 inches to 1 mile accompanies the report. It is compiled iiom
all available sources, the compiler's route being shown in red.
The heights have been worked out from observations taken with a large
sized aneroid barometer (tested before use in the Mathematical Instrumen ,
Department, Calcutta) and worked out relatively to the height of themeicum
barometer, Bushire, which is assumed to be 25 feet above the sea leve .
tunately the barometer was spoilt one day's march from Bushire on e
sion of my beins: ensrulplied in a swamp. , , „
The readings of the aneroid barometer taken at Basra before commencing
the journey showed it to read 0--2" higher than the average o ® "
standard barometer for the five years 1878—82 an i
along the coast plain, on the conclusion of the journey, showed it to read
lower than did the Bushire barometer for the average of the same five y <
The heights given have been worked out with regard to these two corr ® ct10 '
As the distances from Bushire at which the observations were ma e w
great, the use of the average of 5 years probably gives better results tnan
actual heights of the barometer; these height are given in Appendix JJ.
The barometer at noon at Basra, 20th March, read 30'27 ; tempf;
70° ; and on the 21st, 30-25". All other observations are given m fart iv. ^
