Hence it follows that succinate of strontian is soluble in water. 

 When the solution is concentrated by evaporating, small crystals of 

 succinate of strontian appear; but they disappear when the liquid 

 cools. When the liquid is evaporated to a thick consistency, the 

 succinate of strontian fails in the form of a powder. Tiiis salt has 

 a peculiar taste, not unlike that of muriate of potash. It is equally 

 soluble in cold and in hot water. When succinate of "strontian is 

 dropped into barytes water, succinate of barytes immediately pre- 

 cipitates, showing that barytes has a stronger affinity than strontian 

 for succinic acid. 



VII. Dr. Olinlhns Gregory. 



In the last number of the Philosophical Magazine this Gentle- 

 man has thought proper to insert a most virulent attack upon the 

 Editor of the Annals of' Philosophy, because he refused to admit 

 into this Journal a continuation of his abuse of the Royal Society. 

 The Editor of the Annals of Philosophy considers himself as pledged 

 to the public not to fill his pages with matter totally unworthy of 

 the attention of his readers; and on that score Dr. Gregoiy must 

 excuse him for refusing to circulate low abuse against one of the 

 most celebrated and meritorious societies in Europe. Dr. Gregory, 

 in his last paper, has totally altered the subject on which I animad- 

 verted. He had affirmed, or at least insinuated pretty plainly, that 

 the object of the Royal Society in publishing Don Rodriguez' 

 paper was to sink British astronomers and exalt those of France. I 

 merely said, in answer to this, that the Royal Society had no such 

 object in view ; that it was very possible that an error might have 

 been committed at Arbury Hill, and that the suspicion could be 

 removed only by repeating the observations. Dr. Gregory under- 

 took to demonstrate that it is impossible that an error of 4^" could 

 have been committed at Arbury Hill ; and (forgetting his former 

 zeal for British observers, and his philippic against the Royal Society 

 and the French.) he has appealed to Delambre, a French astro- 

 nomer, who he says is the greatest astronomer now living ; and 

 Delambre thinks it unlikely that there should have been such au 

 error committed at Arbury Hill. Therefore, &c. Q. E. D. 



Now I must acknowledge that I do not perceive any demonstra- 

 tion here. This indeed may be owing to ignorance on my part; for 

 we have Dr. Gregory's authority for saying that I am totally unac- 

 quainted with the subject, that I am no philosopher, and a man of 

 very moderate knowledge and abilities. 



I am well aware that this is not the first, nor the second time, in 

 which Dr. Gregory has indulged himself in this kind of language 

 with respect to myself; nor am I ignorant of the dishonourable 

 motives which induced him to compose the reviews to which I 

 allude; and the cool malignity with which he volunteered ro blast 

 the character and injure the reputation of a man who never had 

 done him any injury, with ubom he was not personally acquainted, 

 and who, having attached himself to a branch of science different
