ment of its Curator, who, with the permission cf the Council, haa 

 continued his Lectures therein to the York School of Medicine, He 

 has likewise delivered a series of highly interesting Lectures on 

 Chemistry, in the Theatre of the Museum, to which the Members of 

 the Society were almost gratuitously admitted ; * and the Council 

 feel assured that had they been able to give sufficient publicity to this 

 fact, previous to the commencement of the course, the interesting 

 nature of the subject, and Mr. Barker's well known talents as a 

 lecturer, would have ensured a more numerous audience. Mr. Addama 

 was likewise engaged by the Council, and delivered three most 

 interesting lectures on the Electric Telegraph of Professor Wheat- 

 stone and on the Solidification of Carbonic- Acid Gas. 



The Observatory has undergone several repairs during the past 

 year ; the usual Observations have been persevered in with diligence, 

 and several interesting phenomena noted. A new Barometer and 

 Thermometer have been placed therein by the hberality of the 

 Curator, who contemplates the delivery of a few Lectures in the 

 course of the present year, the proceeds to be applied in improving 

 the instrumental power of the Observatory. 



Following out the suggestions of the Council, as contained in the 

 last Report, the Curator of Meteorological Instruments has made 

 thirty-six Horary Observations, during the Vernal and Autumnal 

 Equinoxes, and the Summer and Winter Solstices ; and M. Quetelet, 

 of Brussels, has confessed the importance of them, in a letter ad- 

 dressed to the Council, in acknowledgement of the receipt of those

 results have been deduced, viz. :
