 Science at Copenhagen. 



It is evident from the reflections found in 

 the writings of Malcolm Flemming, Layard, 

 and 'other competent observers, that this for- 

 midable epizootia was in its character identical 

 with the one described by Eamazzini and 

 Laneisi in 1711 ; and we feel warranted in 

 saying, after having examined every work of 

 any importance which has treated of that 

 visitation, that it resembles the disease now 

 prevailing among cattle, in its march, in its 

 symptoms, and in its gravity. We believe 

 that these three visitations constitute but one 

 and the same malady, occurring at three dif- 

 ferent periods. This appears to us a most 

 important fact, for if such be the case, the 



tentative treatment of that time deserves our 







most particular attention. Consequently, a 

 few retrospective glances may perhaps be per- 

 mitted us, in considering the subject of cattle 

 disease. 



The medical professors (including several 

 English physicians), who observed and de*
