diet, which experience has shown to be most convenient to thy 

 constitution, until a week previous to the operation, when a vege- 

 table and milk diet will be most proper. No medicine will be 

 necessary, on account of the intended operation, until a few days 

 previous to it. 



When thy wife returns from the Spring Meeting, I will send by 

 her every additional direction; and, in the mean time, am, with 

 great regard, 



Thy assured friend,

Philadelphia, April 11th, 1800. 



Respected Friend : 



Thy letter of the 13th inst. came at a very convenient season, 

 as I have been anxious, for some days, to find an opportunity of 

 writing to thee. I hope to be able to be at thy house in the course 

 of a week from this time ; but do not fix a day, as the calls upon 

 me are so very various and uncertain ; and probably I may be 

 prevented by them from setting off at the time I have fixed upon. 

 * * * * [After some directions, concerning 



a proper regimen, &c, preparatory to the' operation of couchii 

 Dr. W. proceeds] : I have only to add a request, that no Btrang 

 may be invited to attend the operation, as they may interrupt that 

 composure which is necessary, both in the patient and operator, in 

 business of this kind. I expect Dr. Marshall's assistance ; and 

 that is all that will be useful. 



These particulars would have been stated to thy wife ; but she 

 went from this 'town before I expected. No time, however, has 

 been lost, as it would not have been in my power to fix the time 

 before this period. 



With sincere wishes for thy restoration, 



I am thy assured friend, 



C. Wistar, Jr.
