BORIC ACID AND BORAX. 83 



fully 99 F., and the pulsations 102 and 105. No. 13 (old No. 5), also 

 complains of headache on this occasion. This and the febrile excite- 

 ment are continued for several days. By March 2 normal conditions 

 seem to be restored, but there is no notable increase in weight, which 

 on this date is 50 kilograms even. The improvement continues for 

 several days, with occasional relapses into ill feeling and frequent 

 headaches. On March 5 there is again a slight febrile excitement, the 

 temperature rising to 99 F. This, condition passes away, however, 

 the following day, but recurs on the 7th, thus indicating malarial con- 

 ditions. On March 9 the improvement in the condition of No. 13 

 seems to have become permanent, and the administration of the pre- 

 servative is again commenced in a quantity of one-half gram, which is 

 again given in the same quantity on the following day. On this day 

 there is a considerable febrile excitement and headache, evidently not 

 due, however, to the administration of the preservative, as it is exactly 

 similar to that which has taken place at somewhat regular intervals 

 during the fore period. The febrile excitement continues on the fol- 

 lowing day and normal conditions are restored on the 12th, when one- 

 half gram of the preservative is administered, but on the next day 

 this is diminished to one-fourth gram. One-half gram per day is 

 given from the 14th to the 19th, inclusive, during which time there 

 is an apparent improvement in the condition of the patient, the 

 weight having increased on March 19 to 51.4 kilograms. On March 

 20 there is a sharp recurrence of the symptoms of grippe, and the 

 administration of the boric acid is suspended; the temperature runs as 

 high as 101.8 F. and the pulsations as high as 120 per minute. This 

 accession of fever does not seem to be connected in any way with the 

 small quantity of the preservative taken before the attack. This 

 illness of No. 13 continues throughout the 21st with an intensity which 

 causes him to be absent on this day. On the 22d he returns, but still 

 shows a slight febrile excitement, the temperature being 99 F., 

 although it falls during the day at one time to 98.6. On the following 

 day the chart shows that he is not well, but improving, and on the 

 24th, while still improving, the administration of the preservative is 

 recommenced in quantities of one-half gram per day, which are 

 continued through the 26th. On March 27 and 28 the quantity is 

 reduced to one-fourth gram. From March 29 to April 8, inclusive, 

 one-half gram is given. A general improvement in the condition of 

 No. 13 continues until March 31, when he suffers from a slight head- 

 ache, which leaves him, however, on the following day. The headache 

 recurs on April 3 and continues on the 4th. The temperature is 

 normal on the morning of the 4th, but a slight febrile excitement is 

 manifest in the afternoon, the temperature rising to 99.6. The 

 headache and febrile excitement continue without intermission and 

 with accentuation during the 5th and 6th of April, though the febrile
