double ureter. In the lower part of the abdomen there were about 2 lb. of 

 serum tinged with blood. 



Observ. II. Saliva of an unusual colour. — In this second observation we have 

 an account of a man aged 40, of a thin, bilious habit of body, who had an 

 attack of jaundice, followed by colic, which last was occasioned by drinking too 

 great a quantity of cyder. An emetic was first given, then a terebinthinate 

 clyster, and an anodyne mixture; afterwards a cathartic bolus, composed of 

 jalap. 9j, calomel, gr. viij. spec, diambr. gr. vj. laud, solid, gr. j. ; and along with 

 this bolus, a draught consisting of tinct. sacr. §ij. Copious stools ensued in 

 the space of 12 hours, after which an anodyne was administered at night. In 

 the morning the patient complained of pain and swelling of the fauces, and 

 spat up some thick, brownish spittle; soon after the saliva followed in great 

 quantity, and of a deep green colour, like porraceous bile, only thinner. This 

 flux of green saliva continued for about 40 hours, during which the quantity 

 discharged amounted to two sextarii. The colour of the saliva then changed 

 to yellow, like a solution of gamboge, with an increase rather than a diminu- 

 tion of the quantity. It continued of this colour for the space of 40 hours 

 more, after which it gradually became pellucid, and the salivation ceased as 

 suddenly as it had come on. 



Before this illness the patient had suffered two or three attacks of jaundice, 

 within the space of 2 years. Ten years ago he had a very profuse salivation, 

 which came on spontaneously, and brought him into great danger. He was 

 then cured by Dr. Pyne. But at that time not a particle of mercury was given, 

 nor was the saliva at all coloured. 



Dr. H. remarks that this appears to be a most extraordinary case, whether 

 the salivation be considered as having come on spontaneously, or as having been 

 excited by the single dose, (gr. viij) of calomel; which he knew to have been 

 rightly prepared, and of which he had prescribed in many other instances larger 

 doses, without producing any effect upon the salivary glands. During the flow 

 of saliva in this patient, the teetli and fauces were as green as if they had been 

 stained with verdigrise. The teeth retained this colour for the space of a fort- 

 night after the patient's recovery. The author further remarks that this sali- 

 vation proved critical both of the jaundice and colic; for from the moment 

 that it took place, the pain of the bowels ceased, and the greenish colour of 

 the skin began to go off, while the urine was secreted more abundantly, but of 

 a blackish colour. It is further remarked that though the patient was before 

 extremely languid and almost dying, yet he bore this profuse salivation well. 

 Dr. H. considers the large quantity of cyder which the patient drank, as the
