CASE dirty flannel jacket, whence the swarms were successively supplied 

 which astonished beholders ; and the further history of the case 

 was, that so soon as the dirty flannels were burned, the mysterious 

 disease disappeared, and the patient recovered. Such, we have no 

 doubt, would be found to be the rationale of Lady Penruddock's 

 case, and of all similar recorded cases of the disease of P. tabes- 

 centium, which have obtained credence from not having been 

 examined at the time." 



Before leaving this subject, it may be desirable to say a word 

 or two as to the best mode of getting rid of these vermin. The 

 treatment employed in the metropolitan hospitals and poorhouses, 

 which has the recommendation both of ample experience and 

 complete success, is the application of "white precipitate," which 

 is the bicarbonate of mercury in the form of an ointment. It kills 

 them at once.
