 a blow-pipe, or the flame from the discharge of a mortar, attended

 fore the wind. 



95. Its appearance on the 14th 

 is shown, on the same scale, in 

 fig. 15. The principal flame was 



now greatly enlarged, extending to the apparent length of 134". 

 Its deflection and curved form were most remarkable. 



96. A cloudy sky prevented all observation for 12 days. On 

 the 27th, the comet appeared to the naked eye as bright as a star 

 of the third magnitude, the tail being distinctly visible. The 

 coma surrounding the nucleus appeared as a uniform nebula. 

 The tail was curved and of great length ; but, owing to the low 

 altitude at which the observation was taken, it could not be 

 measured. On the 29th, however, the comet was presented under 

 much more favourable conditions, and the drawings, fig. 16 and 

 fig. 17 were made. The former represents the entire comet, 

 including the whole visible extent of the tail, and is drawn to the 

 annexed scale of minutes.
