closely resemble the Belgian soils analysed by Sir Robert Kane, as may be 
seen from the tables which they borrow from Sir Robert’s paper.

In conclusion, the authors express their warmest thanks to Dr. Hofmann 
for his instruction and valuable advice during the prosecution of these 
analyses. (o. the details in the ‘ Proceedings’ of Chemical Society.) 
That we may have a complete view of what is required in 
soils for the successful culture of Flax, we adduce Sir R. 
Kane’s analyses of three Irish soils and one Belgian, from the 
report of the Flax Improvement Society of Ireland. The Irish 
soils, as described by Mr. M‘Adam, were from the counties 
of Londonderry and Tyrone, and were considered very good 
for Flax. The Belgian was from Duffel, in the province of 
Antwerp, and may be taken as representing a third-rate class 
of Flax soil in that country, requiring much manure, but pro- 
ducing good crops. The large proportion of sand and the little 
moisture in this last, deserve notice :
