attacked them. After they had continued thus for some time, the pain ascended 

 towards and above the stomach, and very violent motions ensued, especially 

 about the stomach and belly ; by which they were convulsed in the whole body, 

 with some foaming at the mouth, in the interim of their fits ; these symptoms 

 continued increasing until the latter end of August, when they were taken 

 with the dread of water, and could not endure to look on any thing liquid, 

 but would have fallen into a fainting fit, and have so lain some time ; and then 

 would have tossed about in the most violent motions, groaning very much ; and 

 usually, the eldest especially, snarled, barked, and endeavoured to bite like a 

 dog. They continued in this fit sometimes for an hour, at other times less, and 

 then came out of the convulsive-like motions, lying as in a swoon ; but a little 

 after they would appear as well as ever. The symptoms continued until the 

 middle of September, the fits coming on every day, during which they could not 

 speak ; but, in their intermissions, were as towardly and well as ever. 



About the middle of September, at which time, especially, their barking and 

 snarling like a dog came on, they became more wild ; so as for some days, 

 even while out of their torturing fits, they would, every now and then, not 

 endure company, not so much as come near each other ; this disposition con- 

 tinued for a week ; and then the eldest drew near his father, saying, as one 

 surprized, father, I am well; and they both became so well, as not only to 

 converse with their friends, but also to look into the water without any dread ; 

 and were as well in their senses as ever, and so continued for 3 or 4 days ; but 

 after that they fell ill again, and remained ill 6 or 7 days ; after which, they 

 recovered again, saying, as before, suddenly to their father, father, I am well ; 

 this was about the end of September, and they continued both as well as ever 

 they were to appearance, till the end of January, when the eldest had some fits 

 like the former ; but the youngest remained as well ever since. 



We should observe that in August, when the symptoms were first supposed 

 to proceed from the poison of a mad dog, doses of antimony and mere, vitas 

 was prescribed, which accordingly were administered ; with antidotes of venice 

 treacle, powder of crabs' eyes, and other things. 



On the Imperfections in an Organ. By Dr. Wallis. N'^ 242, p. 249. 



It seems evident, that each pipe in the organ is intended to express a distinct 

 sound at such a pitch ; that is, in such a determinate degree of gravity or 

 acuteness ; or (as it is now called) flatness or sharpness. And the relative or 

 comparative consideration of two or more such sounds or degrees of flatness
