2SG Mr.' South on Astronomical Phenomena. 



It was my intention to have concluded this paper with some re- 

 marks upon the preparation of cinchonia and quinia, and upon 

 the relative medical effects of these substances in their pure states 

 and in the form of salts, but the experiments connected with these 

 subjects not being yet complete, I shall reserve them for a future 

 communication. 



The cinchonia which I used in the above experiments, was 

 prepared for me with much care, by Mr. Faraday, in the laborar- 

 tory of the Royal Institution ; and the quinia was made by Mr. 

 Ilennell, at Apothecaries' Hall, where considerable quantities of 

 the sulphate of quinia have already been prepared for medical 

 use. In the case of intermittent diseases the latter^salt appears 

 rising in reputation, and promises to come into as general use 

 in this country as in France, where it is universally substituted 

 for the bark in substance in cases of ague. Upon this sub- 

 ject some interesting details will be found, in a communication 

 from Dr. Elliotson, to the Medico-Chirurgical Society, published 

 in the twelfth volume of their Transactions. 



Art. XIV. Astronomical Phenomena arranged in order 

 of Succession for the first Three Months of the Year 1824, 

 computed for the Meridian and Parallel of Greenwich. 

 By James South, Esq., F.R.S. 



Convinced that next to the daily corrections in right ascension 

 and north polar distance of the 46 principal stars*, there is 

 nothing so much wanted in our observatories as an Astronomical 

 Ephemeris, and regretting some one more adequate to the task has 

 not yet undertaken it, I avail myself of Mr. Brande's kindness, 

 which enables me through the medium of this Journal, to present 

 the public with a list of astronomical phenomena, arranged in 

 order of succession, for the first three months of the year 1824: 

 computed for the Meridian and Parallel of Greenwich. 



* In the Annah of PhilosopJiy for the present month, I Lave puhlished the 

 daily corrections in right ascension of 37 Stars of the Greenwich catalogue.
