SHEFFIELD SCIENTIFIC SCHOOL 145 



1870, of the Bussey Institution of Harvard Univer- 

 sity — referred to at the time as ' ' the nearest thing we 

 in Massachusetts have to the experiment station, and 

 capable if rightly handled of doing great good" — Pro- 

 fessor Storer became its dean, as well as professor of 

 agricultural chemistry in Harvard University. He 

 held many tastes and sympathies in common with Pro- 

 fessor Johnson. When the letter follomng was writ- 

 ten, he was engaged in the general practice of his 

 profession in Boston.

New Haven, Conn., June 5th, 1860. 



My dear Storer, — I am much obliged to you for your good 

 ofifices in the coal tar line. I should like specimens of pretty 

 good size of the various products viz., of "naptha, " "carbo- 

 line" and "dead-oil," two gallons or more, up to 5 gals, of 

 each. A chunk of pitch "as big as a piece of chalk" would 

 be very acceptable as a sample. As to napthaline, 1 leave the 

 quantity to your discretion as I have not the slightest idea 

 how large the yield is, or how much could be "run off" "just 

 as easily as not." 



I would be glad to get a few ounces ; but would not refuse 

 it pound-wise. The main point is not to abuse the generosity 

 of your friend. Of that you can judge. Don't be afraid to 

 make the quantities smaller, dovTi to any minimum, if you 

 think those I have mentioned are too steep ! 



Brush desires you to give his remembrances to Warren, — 

 also express to him my thanks for his kindness in rendering 

 us such service. 



I neglected to invite you to call at 95 Wall and stay with 

 me whenever you are in New Haven. Do so by all means, 

 and I hope when I see you next I shall have some comfortable 

 amount of vim in me. Yours with thanks, S. W. Johnson.
