succ. liquorit.; had a dose of cooling physic; rode and walked out a little some- 

 times; had a few anodyne draughts with 7 or 8 drops of laudanum; but it could 

 not be observed that she got any benefit from them, except that she sometimes 

 thought the oil of almonds gave her a little ease. She had a slight appearance 

 of the menses about 4 or 5 days after the accident happened, though it was then 

 only about the middle of the usual period; coughed up at times some small 

 quantities of blood, and had also some mixed with her stools and urine. The 

 reason why the laudanum, the most effectual and universal anti-spasmodic, was 

 used in such small quantities was, that it was known before that she could never 

 bear above 8 or Q drops of it, as the common dose used to affect her with vio- 

 lent sickness at stomach, giddiness and pain in her head, &c. to so great a de- 

 gree, that for some years past, she neither would take, nor durst her husband 

 administer, a larger dose to her. 



The above effects of ipecacuanha, Dr. S. believed, very seldom happened, and 

 no doubt arose from some peculiarity of constitution. Medical writers, as far as 

 he could recollect, seem to have taken little or no notice of its ever producing 

 such an effect as the above. Quincey however, if he remembered right, men- 

 tions its producing asthmas; but then he seems to mean, that it has that effect 

 sometimes when taken internally, but not by means of its effluvia. Mr. Leigh- 

 ton, a reputable surgeon and apothecary in Newcastle, told Mr. S. that tlie 

 effluvia of ipecac, had the very same effect on his wife, as it is above described to 

 have had on Mrs. S. ; and that he had once, in particular, very near lost her 

 from having some of it powdered in his shop. The ipecac, which had the above 

 effects on Mrs. S. was the common officinal ash-coloured or grey kind. Oct. 20, 

 1775, Mrs. S. had quite recovered her flesh, strength, colour, &c. Dr. S. 

 sometimes thought since, that musk in pretty large doses might have been of 

 service to her. 



JT. On the Success of some Attempts to Freeze Quicksilver, at yilbany Fort, in 

 Hudson s Bay, in the Year 1773: luilh Observations on the Dipping Needle. 

 By Thomas Hutchins, Esq. p. 174. 



Mr. H. made his first attempt to freeze the quicksilver on the 19th of January, 

 1775. The thermometer at 8 o'clock in the morning was at 37" below O; but 

 between 10 and 1 1 it stood at 28°. Mr. H. took the same thermometer and the 

 best spare tube he had, which admitted only of 250° below O, and immersed them 

 both together in a large tea-cup filled with snow, and poured on sp. nitri fumans 

 glauberi till the snow was dissolved; but finding it did not cover the bulbs, he 

 added more snow and spirit till the bulbs were entirely covered in the mixture, 

 which was now liquified: the quicksilver subsided very gradually to 130", and 

 then stopped. He had another cup at hand, and mixed some snow and spirit in
