BORIC ACID AND BORAX. 77 



headache on the 31st, the appetite being poor, the subject complaining 

 of a general miserable feeling, with a peculiar burning, heavy sensa- 

 tion in the stomach. This feeling has existed for several days before 

 the 31st, but has not been deemed worthy of note until that day, it 

 having increased greatly for a week or ten days, according to the 

 statement made by No. 2. June 1 brought no relief from these ill 

 feelings, the headache persisting, appetite poor, and the general feel- 

 ing of discomfort continuing. No improvement is noted on June 2. 

 The discomfort complained of is not sufficiently pronounced to prevent 

 the subject from attending to his ordinary duties. The appetite, how- 

 ever, has so diminished that No. 2 is not able to eat the whole of his 

 rations on June 3, the headache and the heavy, burning sensation in 

 the stomach being very pronounced. These symptoms continue with- 

 out intermission and are somewhat accentuated on June 6. On the 

 following day there is an improvement in the symptoms and the appe- 

 tite is also better, but this gain vanishes on the 8th. The severe 

 headache continues all day on the 9th, but is not so pronounced on the 

 10th, though the improvement in the appetite is not noticeable. On 

 the llth and 12th the headache is not so severe and the appetite is a 

 little better. The administration of the preservative was discontinued 

 after the llth. By the 14th the appetite seems to be quite restored, 

 though the headache and other ill feelings are not entirely gone. 

 On the 15th of June there is quite an improvement, but this is only 

 temporary, and all the troublesome symptoms of the bad headache 

 return on the 16th. During the remainder of the period there is some 

 slight improvement and the discomfort is not so well marked. The 

 temperature and pulsation remain normal during the whole time. 

 There is no tendency nor indication of diarrhea nor of any other dis- 

 turbance of any consequence save those noted. 



The after period sees a general improvement and disappearance of 

 the headache and burning sensations in the stomach and the general 

 feeling of malaise. On the 29th of June, when the observations 

 cease, No. 2 is apparently restored to a perfectly normal condition. 



The data in the above case are even more pronounced than in the 

 case of No. 1 in showing a direct connection between the headache, 

 heaviness and burning sensations in the stomach, and general discom- 

 fort, on one side, and the preservative which has been administered 

 during this period of fifty days, on the other. 



No. 3W. S. 0. 



At the beginning of the fore period there appears to be a slight 

 febrile excitement, the temperatures recorded being 99 and 99 F. 

 and the pulsations 84 and 94, respectively, before and after dinner. 



This condition persists for two or three days. By the 27th, how- 

 ever, the temperature has fallen almost to the normal, although the
