tainly there was a surface wind blowing smoke to a 

 different point from any of the clouds above ; and the 

 clouds were of at least three kinds, and had two distinct 

 directions in well marked levels. We may, therefore, be 

 quite sure that there were several currents of wind one 

 above the other. At 8 o'clock very little cirrus clouds 

 were visible. Large low cotton wool masses of cumuli 

 were sailing rapidly toward the sun — lower surface wind 

 still from the W. — but weather conditions distinctly 

 changed. It was a brilliant morning until nearly noon, 

 when it clouded over and came on a snow flurry, which 

 did not last long. A few minutes after 1 p.m. it cleared, 

 the cumulus clouds drifting to the S.E. The high cirrus 

 clouds were still far above, and still cross hatched as 

 before, and held their course east. They continued on in 

 this way for the afternoon, when seen, and on Sunday 

 following, but there was no noticeable renewal of 

 northern lights.

About half a century ago. I saw this written over the greenhouse of the famous 

 Dr. Ward, originator of " The Wardian Case" It is in Virgil. He defied anyone to find 

 out where. So do I. 



Flora seems to have brought out her works in three 

 successive volumes. 



I. Plants without leaves. 

 II. Flowers with straight veinxl leaves. 

 III. Blossoming flowers with net-veined leaves. 

 (By " Blossoming flowers " is meant those with petals and sepals 

 instead of petaloids). 



These three kinds of plants are distinct in every respect'
