He thinks the toxic sub- stances formed in the stomach and intestine are probably the result of the breaking down of the bodies of the ba- cilli by the digestive juices, and that to the absorption of these the various tissue-changes and fatal terminations are to be referred. In a lengthy and interesting review and comparison of Sanarelli's and his own work, Sternberg1 concludes that the Bacillus icteroides of Sanarelli is identical with the Bacillus x, which he had discovered in yellow fever cadavers as early as 1888, and felt disposed to describe as the specific cause of the disease, except for a few facts, such as finding it in only one-half of the cases, etc. Sternberg seems inclined to believe in Sanarelli's work, and asserts his intention to further investigate Bacillus x. Bacillus .ir was, however, isolated from the alimentary canal, in which Sanarelli's bacillus is said not to exist, and was isolated from the liver of a case of tuberculosis, wliicli takes away considerable of the evidence of its specificity. In a later paper2 Sanarelli discusses the validity of Sternberg's claim to priority of discovery, and points out a sufficient number of differences in the original descrip- tions of the organisms to establish conclusively the in- dividuality of the Bacillus icteroides. It would seem, from a careful consideration of the recent literature, that Havelburg had very little ground for considering his bacillus specific, and that it is not possible for Sternberg to establish the identity of the Bacillus x with the Bacillus icteroides, while at the same time Sanarelli's descriptions arid arguments are convinc- ingly in favor of the accuracy of his own work and the specificity of his bacillus. 1 CentraWL fi'tr Bakt. und Parasitcnk^ Sept. 6, 1897, Bd. xxii., Nos. 6 and 7. 2 //>/</., Htl. xxii., Nos. 22 and 23, p. 668.
