others if he had first demonstrated the existence of his agent 

 as a source of disease. There may be abundance of unspent 

 volcanic agency in Scinde, but the author has failed to pro- 

 duce satisfactory proof of its existence. We have purposely 

 avoided all general remarks regarding the nature of malaria, 

 and also all notice of our author's observations regarding 

 other parts of Scinde, besides Sukkur. Our object has been 

 solely to show in a few words the inadequacy of the views, 

 so dogmatically laid down by him, to account for the sick- 

 ness at Sukkur. For ourselves we have not the materials for 

 forming a satisfactory opinion on so difficult a question, and 

 we believe that the experience of the past year has shown 

 sufficiently that its unhealthiness is not of a permanent cha- 

 racter. 



We would now venture to caution our author against 

 being run away with by theory, and having done so, we have 

 much pleasure in saying, that Dr. Kirk's topography con- 

 tains a very considerable amount of useful and interesting 

 information, and many curious facts regarding malaria. 



Case of Duplex Monster. By J. W. Bedford, Esq. 

 Assistant Surgeon. 



I received intelligence of the birth of a Monstrosity : on 

 hastening to the house I found the twins as represented. 

 They were six days old, small but healthy. The fleshy 

 band of union stretched from the apex of each sternum. 

 The band was soft, as though containing intestine, which 

 percussion did not verify however. It was two inches from 

 above to below, one inch from before to behind. No pulsa- 

 tion : one common umbilicus in centre of inferior surface. 

 Respiration independent : circulation difficult to be apprecia- 

 ted. Defecation independent, one wakes, whilst the other 

 sleeps. Both females, the aspect of one is more lively than 

 that of the other.
