Frost freaks of herbaceous plants.—The very interesting article by 
L. F. Ward on“Frost Freaks of the Dittany”? called to my mind some 
very interesting observations which I made on this plant during the 
winter of 1885-6, while connected with the University of North Caro- : 
lina. This plant is very abundant in the open woods at Chapel Hill 
where the University is located. During a short excursion one frost] 
morning the curious frost foils on the stems of Cuni/a attracted my a 
tention. On these particular plants the frost laminations did not : 
usually conform to the regular arrangement described by Mr. Ward, 
though sometimes the regular arrangement in whorls of two oF fout 
did occur. The sheets did however stand out vertically from long | 
tudinal slits in the stem and were curved into multitudinous form’ 
forming imitations of numerous objects. One case I particularly wy
