392 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



They have heretofore commended themselves to the judgment 

 of those who have had to deal with the subject. Another, 

 however, of great importance in a commercial and sanitary 

 point of view, was added, namely, the requirement that every 

 state in which the cattle disease manifests itself shall make 

 announcement of the fact immediately, by telegraph, first to 

 the neighboring governments, and ultimately to those more 

 distant. A careful inquiry is to be made as to the route of 

 introduction and propagation of the disease, and the results 

 are to be, with the least possible delay, brought to the knowl- 

 edge of the authorities of all the countries menaced by the 

 invasion of the plague. Wherever the disease has actually 

 broken out in a country, it is to publish in an official journal 

 a weekly bulletin showing the stage of the disease, the meas- 

 ures adopted for its prevention, the successive modifications 

 of regulations which are to be introduced according to cir- 

 cumstances, and, finally, the day in which they cease to be in 

 operation ; this bulletin to be sent to the editors of official 

 journals of other states when they desire it. 



The convention found that, among the various countries 

 that had had occasion to take measures for the proper disin- 

 fection of cattle-cars and other vehicles of transportation, 

 Germany had the most satisfactory arrangements. Here, 

 after a train has been emptied of its contents, the cars are 

 immediately deluged with warm water of at least 160Fahr. 

 The shock and strength of the current, falling from a consid- 

 erable elevation, detaches all organic material adhering to the 

 wood-work, and, by the elevation of temperature, annihilates 

 all virulent activity. 



The principal point established by the convention, accord- 

 ing to Bouley, was the necessity of an obligation to slaughter 

 all animals as soon as the disease made itself manifest, or as 

 soon as there seemed a probability that an animal would be 

 attacked. In this way the plague will be arrested by sacrifice 

 of the smallest number of animals. 6 B, April 29, 1872, 1154. 



NEW INSECTICIDE. 



A formula, recently introduced in Great Britain, for de- 

 stroying caterpillars, consists of a mixture of coal dust, com- 

 mon salt, and flour of sulphur, to be scattered just before a 

 rain over freshly-plowed land. To exterminate caterpillars
