CLASS XIV. 

 DIDYNAMIA. 



< ' We content ourselves with the knowledge of the tongues, and a little skill in 

 philology, or history, perhaps, and antiquity, and neglect that which to 

 me seems more material, I mean natural history, and the works of the 

 creation. I do not discommend, or derogate from those other studies. I 

 should betray mine own ignorance and weakness should I do so ; I only 

 wish they might not altogether justle out, and exclude this. I wish that 

 this might be brought in fashion among us ; I wish men would be so 

 equal and civil, as not to disparage, deride, and vilify those studies, 

 which themselves skill not of, or are not conversant in; no knowledge 

 can be more pleasant than this, none that doth so satisfy and feed the soul : 

 in comparison whereto that of words and phrases seems to me insipid 

 and jejune." RAY.
