ON THE INDIAN, &C, 



Another circle is suspended within this sphere on the 

 poles of the horizon, apparently intended to measure 

 the altitude and amplitude of an object. 



Another sphere or assemblage of circles is in like 

 manner suspended on the pole of the equator. It con- 

 sists 06 both coiureSj and the equinoctial, with the 

 ecliptick adjusted to it ; and six circles for the plane- 

 tary orbits adjusted to the ecliptick ; as also six diurnal 

 circles parallel to the equinoctial, and passing through 

 the extremities of the several signs. 



This, though not a complete description of Bha's- 

 caiia's armillary sphere, will convey a sufficient notion 

 of the instrument for the purpose of the present compa- 

 rison ; and will justify the remark, that its construction 

 differs greatly from that of the instrument specified by 

 Ptolemy. 



In the description of the armillary sphere cited from 

 the Silrja sldd hanta, mention is made of several stars 

 not included in the asterisms which mark the divisions 

 of the ecliptick. The following table exhibits the po - 

 sitions of those, and of the few other stars which have. 

 been particularly noticed by Hindu astronomers. 



t The S calya sanlita and Tat^ua vi'vcca agree with the S'lrya 

 sidd'/iinta as to ihc p sitions of the first ibur staid. They omit the 

 other three.
