 microFcopy. I'rof. Prit chard will give a course of lectures on 

 the theory of the tran-it instrument ard on the planetary theory, 

 and will ii-rm an elementary ilass three eveiiirgs a week at the 

 Univeis ty Ob>eivaiory. Pr. f. Lawson lectures on vegetable 

 histology at 1 he Boianic Garden; Prof. Maskelyne on ci^^tallo- 

 graphy ; and Prof. I're twich on the principles of teology at the 

 Mu euni. Prof. We^tw od gives informal instruction on the 

 Arthropoda every afternoon. 



At Chri't CI ur. h Mr. Verron Harcourt gives a course of lec- 

 tures on the metallic elements, and Mr. Barclay Thompson a 

 course oil the lemurida; and Simiadje. At Magdalen Mr. Vule 

 contiinies his demonstrations on the chemistry of the lis^ues and 

 secietims. At Halliol Mr. Dixon forms a class for the dettr- 

 minaiion of the composition and vapoui-dm ity of organic 

 sub>iances. At Extter Mr. Morgan lectures on histology. 



At Trinity College the Millard Scholar-hip in Natural Science 

 has been awarded to Mr. A. E. Field from the Modern School,
