CHAPTER V 



i. OBSERVATIONS AT BASSOUR 



The observations given in tables I and II were made at Bassour, 

 Algeria, during the period July io-September 10, 1912, at a height 

 of 1,160 m. above sea level. In regard to the general meteorological 

 and geographical conditions reference may be made to the introduc- 

 tory chapter. Every observation was taken under a perfectly cloud- 

 less sky, which in general appeared perfectly uniform. In regard to 

 the uniformity of the sky, I may refer to chapter VI, where some 

 observations are given that can be regarded as a test of the uni- 

 formity of the conditions.
