R. College of Chemistry
Oct. 27. 1860.
My dear Sir
I enclose you the book on poison from which my statement about arsenic was taken. Taylor explains his opinion so well that I need not add a word.1
I have made a few experiments with Iodine and find that 0.001 milligramme of iodine dissolved in 1 Gramme of water is scarcely indicated by the starch test,—but that 0.002 Milligrammes dissolved in 2 Grammes of Water is easily distinguished by that test.

Hoping that this information will prove useful | Yours very truly | A W Hofmann
