266 EUROPEAN AGRICULTURE. 



such as to satisfy the original subscribers of its utility. It has 

 led, through the lectures of the professor, to the establishment 

 of several agricultural periodicals, and has throughout Scotland 

 infused new spirit into the veins of the agricultural body, and 

 quickened its pulse. One of the most substantial benefits as yet 

 resulting from it has been the analytical examination of ninety 

 different specimens of guano imported into Scotland ; and that 

 to secure the farmers from impositions, which, in cases before 

 this, have not been infrequent. 



After the remarks which I have made in a former part of my 

 Report, it certainly is only just that I should subjoin the analysis 

 made at this place of two soils from Renfrewshire, with the 

 results of the application prescribed for them.

But a mere trace of magnesia and phosphoric acid was found 

 in either of these soils. It was therefore recommended to add 

 to both of them the magnesia in the state of sulphate, and the 

 phosphoric acid as bone-earth. The effect has been most won 

 derful and striking.&quot; The letter with which I have been 

 favored adds, &quot;None of the analyses I have given are very 

 elaborate, but they are sufficiently so for practical purposes, and 

 they do not confuse or mystify the farmer with hard names.&quot; 



I had the pleasure of visiting this institution, and there was 

 certainly no want of the indications of industry. I have only to 

 regret that my friend s account of his two patients above is so 

 short and imperfect. I should be gteid to have been able to 

 inform my readers what was the exact condition of the patients 

 before taking the prescription, and their particular state of health 

 after it.
