82 LETTER-FILES OF S. W. JOHNSON 



of his ''thorough devotion to this branch of science 

 and his sound and discriminating sense, a brilliant 

 career of usefulness to his countrjmen. " Mr. Tucker 

 wrote in April 1854: 



I presimie, from your not alluding to it, that you have 

 neither seen nor heard of the controversy which grew out of 



the publication of your analyses of M 's and D 's 



superphosphate of lime. I shall send you all the papers, if 



I can find them, in relation to it. You will see that M , 



instead of publishing your letter as I supposed he would 

 with his thanks for the credit you gave his superphosphate, 

 chose to assail your motives in making it, and made an effort 

 to prove it all erroneous. I do not think, however, that your 

 reputation has suffered at all from his attacks. 



I am very greatly obliged to you for your letters and shall 

 be grateful for any more sheets with which you may favor 

 me, both of letters and translations ; and I deeply regret that 

 the income from my paper will not warrant me in offering 

 you such compensation as you deserve. The publication of 

 your letters will serve to make you known and will, I trust, 

 in this way be of some benefit to you ; besides this, I shall try 

 to make you some reward for them hereafter. 



(L. T. TO S. W. J.) 



Albany, March 6, 1855. 



Dear Sir, — ^Your favor with the copy of Prof. Liebig 's work 

 came to hand on the 2d. inst. . . . — on reading it, I came 

 to the conclusion that the better way would be to issue it in 

 a pamphlet. . . . This method of publication I trust will meet 

 the approbation of Prof. Liebig and yourself. I shall secure 

 the copy-right for your benefit, and place the profits, should 

 there be any, to your credit. I do not know, of course, what 

 the demand will be for it, but I hope it will be such as to yield 

 you $50 or so.
