from the United Kingdom is prohibited by local and provincial 

 regulations in Prussia, Mecklenburg-Schwerin, Oldenburg, 

 Liibeck, Hamburg, and Bremen. Exemption from this pro- 

 hibition is granted in the case of breeding sheep or breeding 

 swine. Such animals, if they have not been shipped with 

 animals liable to quarantine, are exempt from quarantine, and 

 the admission is made dependent only on the veterinary 

 examination at the place of entry. Proposals for the admission 

 of such animals must be addressed to the central authority 

 of the State to which the consignment is to be sent. The 

 applicant must then apply to the central authority of the State 

 through which the entry is to take place for the admission 

 of the animals, producing the permission of the first-named 

 authority. 



The importation and through transit of horses from the 

 United Kingdom is restricted by local and provincial regula-

 and Bremen. Horses for importation must be examined at 

 the landing place (or on board ship) as to their state of health 

 by an Official Veterinary Surgeon, and those suffering from 

 or suspected of contagious disease will be refused admission. 



All cattle received in the quarantine stations must be 

 examined for tuberculosis and other diseases and undergo 

 the tuberculin test. Those which react will be turned back 

 after being branded on the left hind-quarter. The importer is

 if this is not done by a given day the police authorities must 

 have the animals destroyed. A fee of is. 6d. must be paid for 

 the tuberculin test in addition to the quarantine fee.
