This last sti-ength would continue till the two bottles were 

 exhausted on the lltli day, when the whole of the 2 chi, equal to 

 116.666 grains would have been taken. In the above computation, 

 figures beyond the third place of decimals were discarded, so that it is 

 only approximately correct. If anyone takes the trouble to check it, 

 it will be found that only 116.604 grains of opium are accounted for. 



As the infusion contains no preservative, it is very subject to 

 fermentative and other changes, so that it often becomes putrescent 

 and has to be thrown away before the end of a course. A fresh supply 

 then has to be ol)taiued. This is stated to be of frequent occurrence, 

 consequently only a portion of each supply is taken by the patient in 

 many cases. 



About 130 gallons of infusion are being made and distributed to 

 the Chinese per day and the niimber of patients being treated is now 

 (24th Nov.) from 260 to 270. The society began work on the 3rd 

 November and from that date to the 23rd November 6,130 people applied 

 for and were given the infusion. This is equal to a daily average of 292 

 patients. Accurate records appear to have been kept by the society, 

 and there would seem to be no reason to doubt the correctness of these 

 figures. The whole woi-k is most methodically carried out. Each 

 applicant receives a printed slip of paper containing the directions in 

 Chinese as to the use of the drug and a wooden check, at the office ; 

 the latter he presents at the factory and receives in exchange two
