had ceafed. The animal remained very fti!!, and after oil had been applied to the fwellings, 

 was left all night in a bafket of hay, in a warm fituation. 



January 27. The rabbit had left his bafket; a little warm milic was given him. In theeven- 

 ing he eat his parfley, and drank his water heartily. On the evening of the 28th, the power of 

 the antidote being fuppofed to be afcertained, the rabbit was killed, and a furgeon was defired 

 to examine the fwellings. He found that they arofe from an enlargement of the maxillary 

 glands, and of the lymphatics. The ftomach was covered with a number of fmall fpecks, 

 and feemed a little foftened. It fhould be obferved that this rabbit had been kept on dry 

 food,' which may account for the comparatively flow adtion of the fulphure. An accident con- 

 firmed this : in the courfe of the experiment, having put his nofe into water, he received fome 

 on his tongue, which being fwallowed, greatly increafed his agonies. Ic happened (hortly be- 

 fore the oil was given. The fulphure had been carefully prepared. The experiment with 

 the folution of calcareous fulphure was twice repeated: each time the rabbit died in lefs than 

 two minutes. The ftomach was black and yellow, fpongy, and much corroded.

To Mr. NICHOLSON. 

 SIR, 



SEND you the Weft-country contributions, fuppofing that it fells within your plan to 

 announce the publication. You will do this the more readily, as an article in your laft 

 number erroneoufly reprefents Dr. Gibbes as the difcoverer of the fulphate of ftrontian in- 

 this neighbourhood. This miftake you will fee correded in a note* to my table of contents. 

 Whether Mr. Richardfon told Dr. Gibbes what he had learned from Mr. Notcutt, viz. that 

 the fpec'imen he gave the doff or was fulphate of flrontian-^ I have not yet learned ; but I fuppofe 

 he didjbecaufe it is fo very natural to do fo, inprefenting a fpecimen; andbecaufe Dr. Gibbes,, 

 as it appears, immediately direfted his experiment according to that fuppofition. The title of 

 the paper, no doubt (Difcovery of Sulphate oi Strontian, near Sodfaury, by T. S. Gibbes, 



• The note here alluded to is as follows. — A» Dr. Gibbes has related an experiment of his own on the Sod- 

 kury fulphate of ftrontian in Mr. Nicholfon's Journal, March, 1799, without referring to any other perlbn's 

 previous obfervations, it feems but juft to mention the following circumftances : In the colle6tion of the Rev. 

 Mr. Richardfon, at Bath, a friend of mine (Mr. Notcutt), inftrufted bv Mr. W. Clayfield's fpecimens, pointed 

 cut fome fulphate of ftrontian. Mr. Richardfon gave a piece to Dr. Gibbes, in January laft. I had exhibited this 

 fubftance, as found in other places near Briftol, to a large audience, nine months before, viz. in Spring, 1798, 

 and had fent fpecimens to Mr. W. Henry, who communicated the facft to the Philofophical Society, at Man- 

 chefter. Dr. Gibbes does not, undoubtedly, mean to claim the difcovery. He knew laft year that Mr. 

 Clayfield was analyfing the foffil. Hundreds of perfons might have anticipated Mr.C. in announcing the faft. 

 It is, indeed, I obferve, diftinftly noticed in the- Appendix to the Monthly Review, vol. xxv, p. 580, June, 1798, 

 The manner in which this fulphate was detefted in this aeighbuurhood is exactly related below.
