resistance is brought about. The resistance thus produced is temporary since ani- 

 mals which have withstood large injections of anthrax bacilli mixed with sonic other 

 organism may succumb later to a small quantity of anthrax bacilli. The organism 

 most extensively used by the author for mixing with anthrax is /.'. enteritidi*. 



The effect of corrosive sublimate in experimental anthrax infection in 

 naturally immune animals, D. Calamida (Centbl. Bakt. u. Par., 1. AbL, Orig., 87 

 (1904), No. 1, pp- 11-18). — The author's experiments were carried out on dogs and 

 chickens, both of which are generally known to possess a high immunity toward 

 anthrax. 



It was found in these experiments as already pointed out by Cadeac that the 

 injection of nonfatal doses of corrosive sublimate one-halt hour before inoculation 

 with anthrax produces death as a result of anthrax infection in full-grown dogs which 

 were otherwise immune Jtq ward the anthrax bacillus. Similar injections of corrosive, 

 sublimate did not have the effect of destroying the natural immunity toward anthrax 

 in chickens. Experiments with digitalin showed that when this dru>r was injected 

 after inoculation with anthrax and treatment with corrosive sublimate it counteracts 

 the deleterious influence of corrosive sublimate. This action is attributed to the great 

 hvperleucocytosis brought about by the digitalin. 



The effect of corrosive sublimate is apparently due to its specific action upon the 

 white blood corpuscles and the fact that chickens remain immune to anthrax even 

 after receiving injection of corrosive sublimate, is attributed to the greater resisting 

 power of their leucocytes. 



Carbuncular diseases of animals, M. Cadiz (Enfermedades carbunclosas de los 

 animates. Santiago <h Chile: Tnstituto Agricola, 1904, pp- ?!• pis. .'. figs. IS). — The 

 author presents a general account of the symptoms, pathological anatomy, distribu- 

 tion, and treatment of anthrax and black leg of domesticated animals. 



Actinomycosis, W. H. Kelly (Rpt. New York State Dept. Agr., l<> (1902), pp. 

 194-198). — The author discusses the nature of this disease together with an account 

 of the means of infection, the symptoms of the disease, and approved methods of 

 treatment. 



Inoculation against African coast fever, C. E. Gray (Jour. Comp. Path, and 

 Ther., 17 (1904), No. 3, pp. 20S-205). — After the publication of Koch's inoculation 

 method for the prevention of this disease, the author tested the method on a large 

 scale. It was found that inoculation repeated 10 or more times failed to produce 

 immunity, other striking instances were observed in which inoculation failed to 

 protect the treated animals, and the author concludes, therefore, that the failure of 

 Koch's method makes it necessary to combat the disease by means of dipping and 

 quarantine. 



Some observations and experiments in connection with tropical bovine 

 piroplasmosis (east coast fever or Rhodesian redwater), A. Theilek and S. 

 Stockman (Jour. Comp. Path, and Ther., 17 (1904), No. 3, pp. 198-208).— Observa- 

 tions in South Africa have convinced the authors that infected fields may become 

 free from infection after a lapse of 15 months or perhaps in some instances within a 

 shorter period. 



A test of the inoculation method proposed by Professor Koch was without satis- 

 factory results. Inoculation repeated 6 or more times failed to produce any immu- 

 nity to the disease. A number of dipping experiment* were carried out with kerosene 

 finely divided in water. The results of these experiments indicate that the disease 

 is not materially checked by this method. Dipping experiments were also made 

 with arsenical dips with or without the addition of Izal. The application of dips in 

 badly infested areas apparently gives no <_ r uarantee against the further spread of the 

 disease. 



Foot-and-mouth disease, A. Declerck (Rev. Agron. Lima, 1 (1904), No. 1, }>}>■ 

 18-20). — Brief notes are given on theetiology, symptoms, and treatment of this disease.
