time, nursed her husband. On March 7th I revaccinated 

 Mrs. F., she having two inferior marks of previous vaccina- 

 tion; she did not take. On March nth I again revacci- 

 nated Mrs. F., when all three places took, and she had a 

 very good arm. On March 2ist, Mrs. F. took ill; small- 

 pox eruption was developed on the 24th, there being fifteen 

 or sixteen pustules. She was very ill for some days, prema- 

 ture labour being imminent; but she did well, and on 

 June 2yth was delivered of a healthy child, the said child 

 having neither pit nor sign of the disease upon it. On 

 July 2oth, August ist, and i6th, I vaccinated the infant, 

 but each time unsuccessfully." 



Case in which Small-Pox was not taken by Unvacdnated 

 Persons. 



For the following facts I am indebted to the Lady Superior 

 of St. John's House. 



"S. L., aged 13, Westminster, took the small-pox in 

 March, 1871. The rash was fully out all over face and body 

 March zoth. The mother and baby of a week old slept in 

 the same bed and continued to do so. The baby has never 

 been vaccinated, and is now nine weeks old, and has been 

 sleeping in the bed night and day. The mother was vacci- 

 nated as a child, 35 years ago. The other children in the 

 room had been vaccinated. The father has never been 

 vaccinated at all, and slept in the same room. No oilier 

 member of the family has had the small-pox." 



Preparation of Vaccine Lymph in Glycerine. 



The fresh vaccine lymph is placed in the hollow of a 

 watch-glass, and there mixed with twice its quantity of Price's 

 pure glycerine and as much distilled water. The liquids 

 are thoroughly well incorporated with a paint-brush. The 

 mixture may be preserved for use in capillary tubes or small 

 medicine glasses. The lymph thus procured is considered 

 equal in effect to pure lymph ; care must, however, be taken 

 to shake it before use, as the particles of vaccine bioplasm 

 gradually subside to the lowest part of the fluid.
