Meteorological Observations. 239 



deration of the Association of Irish Non- subscribing Presbyterians, 

 at their recent triennial meeting held in Newry ; and a Committee 

 of that body was appointed to consider and suggest to the proper 

 authorities any improvements in the Undergraduate course which 

 may appear desirable ; and directions were given, that in the contem- 

 plated improvements, the study of Natural History should not be 

 fogotten. 



When the sober-minded Presbyterians of the north of Ireland are 

 thus giving their deliberate testimony to the importance of the study, 

 may we not hope that a time may yet come when it shall be univer- 

 sallyjntroduced as a regular branch of education both in our schools 

 and colleges ? I am, your very obedient,
