[59] Die medicinischen Chinarinden Neu-Granadas, von H. Karsten: Berlin, 1858. I have had this pamphlet translated for the use of those intrusted with, or interested in, the chinchona cultivation in India and Ceylon. It contains a great deal of valuable information respecting the most favourable situations for the production of alkaloids in chinchona barks, and other particulars respecting the growth of the bark, and the methods of collecting it. Dr. Karsten is a careful observer and a scientific botanist and chemist, and his observations form a very important addition to our knowledge of this subject.
