VI I'UKKACK. 



which \\v (tii^ht iu»t t<i sliriiik. lie has gleaned information 

 from various sources, and has made free use of the labours of 

 the contincntiil pathologists, rather preferring to do this, in 

 many instances, than to j)romulgate opinions of his own. In 

 accomplishing his design, he trusts that he has rendered an 

 acceptable service to his profession, and also one which will 

 be deemed not altogether valueless by the practitioners of 

 medical science, lie is emboldened to make this latter 

 remark, by observing that Dr. Gregory, Physician to the 

 Small-pox Hospital, in his annual report, after narrating the 

 particulars of the outbreak, and of the experiments, says that 

 " the resemblance of this disease to small-pox is very remark- 

 able, both in symptoms, mode of communication, and rate of 

 mortality ;" and " when fully developed, the investigation 

 can hardly fail to throw some new and valuable light on the 

 history of small-pox, and on the relation which it bears to 

 other diseases, both of man and animals." 



.In conclusion, the author has to acknowledge his obliga- 

 tions to many medical friends, among whom he wishes parti- 

 cularly to name, Mr. Ceely, Mr. Marson, and Mr. Erasnms 

 Wilson ; and he is equally indebted to his colleagues Pro- 

 fessors Sewell, Spooner, and Morton, and also to Mr. Varnell, 

 for assistance and advice in carrying out the investigations.
