Peculiarities. — " Plants from the acid keeping the lead, and are a 
heavier crop to-day (Oct. 20th), though not looking quite so healthy 
in the blade, having come earlier to maturity."

Peculiarities. — " The turnips came into rough leaf" sooner on that (the 
sulphuric acid) acre than on any of the other" (Letter of the Duke of 
Richmond, Roy. Journ. Agr., vol. iv., p. 408). " Turnips taken up 
and weighed, Nov. 3rd, before they came to full maturity, as it was 
■wished to ascertain the result while the duke was at the castle." —

The same application Mr. Fleming tried upon potatoes, and the result 
was also, in the language of Professor Johnston, " greatly in favour of 
dissolved bones" — (Appendix to Lectures on Agr. Chem., p. 81). 
Peculiarities. — None noted, except that " the crops braided well," 
and that the applications " which show the greatest weight, kept the 
lead of the others all the season" — (Appendix to Johnston's Lectures, 
p. 55).
