" III. That a different exemplar was employed for, at 

 least, the Acts of the Apostles, and possibly others elsewhere ; 

 but this is urged on grounds too various and subtle for pre- 

 sentation in a short paper : — and 



" IV. That the Latinizing tendency of the manuscript 

 has not been sustained on the grounds alleged." 



Mr. J. H. Smith read a paper on the Cross of Kilnasagart. 



The Rev. Dr. Lloyd read the concluding part of a paper 

 " on the influence of the moon upon the position of the freely- 

 suspended horizontal magnet." 



In a former communication upon this subject the- author 

 had analyzed the diurnal range of the magnetic declination in 

 reference to the moon's age, and shown that its magnitude 

 was subject to a periodical variation, being greatest in the first 

 and third quarters of the lunation, and least in the second and 

 fourth. The moon, therefore, conspires with the sun in its 

 effect upon the diurnal range in the former portions of the 

 lunation, and opposes it in the latter. 



The preceding method of examination, however, only 

 determines the total amount of the effect produced by the 

 moon's action upon the freely-suspended magnet in the course 

 of the day. In order to investigate its law, we must examine 

 the varying position of the magnet at the several hours of 

 observation in reference to the moon's hour-angle. To this 

 question the author now proceeded. 



The observations discussed are those of the years 1841, 

 1842, and 1843, during which they were made at intervals of 

 two hours. The results are tabidated according to the moon's 

 hour-angle in the following manner : 



The scale-readings of the instrument nearest to the 

 moon's upper meridian passage, on each day, are entered in 

 the first column of the Table ; the next following in the se-
