THE BLOOD. 83 



instances in books: in Tulpius one instance; 1 in Morgagni 

 two; 2 in the Philosophical Transactions some instances; 3 in 

 Skenckius's Observations two cases are related from other 

 authors. 4 I have likewise heard of the same appearance hav- 

 ing been observed by the learned Sir John Pringle, Dr. Pit- 

 cairn, Dr. Hunter, Dr. Watson, Dr. Bromfield, Dr. Gartshore, 

 and Dr. Fothergil of Northampton. And other instances have 

 lately occurred to persons of my acquaintance, who have 

 favoured me with a short account of them. 



Mr. French, apothecary in St. Alban street, having informed 

 me that he had some blood by him, taken from a woman the 

 day before, whose serum was as white as milk, he favoured me 

 with a small quantity of it for examination, and with it the fol-

 five years of age, of a fresh complexion, and lusty, has not had 

 her menses for these seven months. She discharges blood some-

 to the piles, and to such profuse sweats in the night, as to be 

 frequently obliged to change his shirt in the morning before he 

 got out of bed, but that, for some time past, his sweats had 

 ceased. That, on September the 23d, he was seized with a 

 bleeding at his nose, which had been preceded by a pain in 

 his head for two or three days. That his bleeding continued 

 till he had lost about two pounds of blood, and then stopped ; 

 and that the serum of his blood was as white as milk. That 

 at ten o'clock .the same night, the hemorrhage returned, and 

 he lost a considerable quantity ; nevertheless, it was thought
