Abstract of a Letter from Mr. Samuel Dale to IVm. Briggs, M. D. F. R. S. 

 Concerning an obstinate Jaundice, accompanied with a very odd Case in Frisian. 

 N°21], p. 158. 



About Christmas, Anno l68g, after much grief and trouble of mind in the 

 foregoing autumn, Grace Dennis, of Braxsted in Essex, was seized with the 

 jaundice ; for which, after having for about 9 months used many medicines as 

 advised by her friends and acquaintance, but without success, she in Sept. 169O, 

 applied to me, when I administered some medicines, famous in the most cele- 

 brated authors for the cure of the jaundice, yet they were of no benefit ; after 

 which she had the advice of several learned physicians in the country and in 

 London, but still without any effect ; for her disease yet continues, and her 

 body, which used to be plump and fleshy, is now become lean and emaciated, 

 almost like a skeleton, and her appetite small and depraved. 



In May, 169I, after an extraordinary menstrual flux for about 3 months, she 

 began, as soon as the sun was down, to be deprived of her sight by degrees till 

 it was quite dark ; when, although ever so large a fire or many candles were in 

 the room, yet she could not discern any object, except a small glimmering of 

 light : and thus she remained until the morning, as one stone-blind, when by 

 little and little, as the light increased, her sight returned, till the sun arose, 

 and then she recovered her perfect sight. And in this case she continued, till 

 August, 1692 ; when being returned from Epsom, where she had been drinking 

 the waters for about a month, her sight returned to her again, so that she 

 could see in the night perfectly. Thus she continued until January last, when 

 an extraordinary menstrual flux again seizing her, her nocturnal sight likewise 

 left her, and she became blind again as formerly. In July, 1693, she was 

 seized with a fever, when her sight again returned, and continued for about a 

 month, and then left her as formerly ; so that now, Oct. 1693, she has her 

 nocturnal blindness, and her jaundice likewise continues.
