Variation in the Ray-flowers 

 of some Compositae.

Sixteen days later, I visited the mountain for the third time. 

 At that time no flower was seen in the crater, but it was in 

 full bloom both in the valley and slope, covering wide area 

 like a yellow band. Following results were obtained : 



Third collection.

Lot Xo. 4 (valley) 

 ., ,, 5 fslfipe) 



In the lot from the valley-, the range has extremely in- 

 creased in both directions, and the polygon was much flattened, 

 with tolerably lowered mode on 16, and with reappeared mode 

 on 13, so that the C w-as also enlarged— the greatest of all 

 the lots. The rrean decreased about half a ra.y% compared with 

 lot No. 3, on account of the greater increase of the lower variates. 



In that of the slope, the range diminished tolerably in the 

 positive extremity, and increased somewhat both in the nega- 

 tive extremity and in the low-er variates. Moreover a new and 

 highest mode appeared on 12, which includes 15.9^^ of the 

 variates, while that on 16 is 15. 3^^. Another slight mode 

 was seen on 14-, and a sinus on 15 as in lots Nos. 1 and 4. 

 Both the mean and C were less than those of the vallev.
