Abstract
WE have already noticed (March 31, 1934, p. 478) the first portion of this monumental work, which dealt in general with the resins. There has now been issued the first half of the special part describing in detail the individual resins. Those chosen are classified as the ester or benzoic resins, commonly termed balsams, and the bitter resins such as myrrh, elemi, etc. The information, covering a very great deal besides botany and chemistry, is of the fullest, and there are copious illustrations, both botanical and otherwise, including pictures of the original packages in which the resins are shipped as well as maps. We know of no other similar subject which has been monographed so exhaustively.
