 in it. 



Dr. Parfonsy the prefent ingenious pro- 

 feiTor of anatomy at Oxford, during his me- 

 dical ftudies at Edinburgh^ as a neceffarv 

 concomitant to the knowledge of phyfic, 

 made botany one of his principal purfuits^j 

 and greatly excelled in it. He was indefa-* 

 tigable in his enquiries into the fcience, and 

 in colledling the objeds of it 5 and with 

 much gratitude I remember the liberty he 

 gave me to reap the fruits of his labours, by 

 permitting me to examine his Herbarium, and 

 extraft from his notes. 



Mr. Yalden^ a late ftudent in phyfic at 

 Edinbtirghy and a mofl fagaciotls and un- 

 wearied naturalift, loft no opportunity dur- 

 ing his continuance in that univerfity, of 

 cultivating his knowledge in botany. He 

 made a copious colledion of the vegetable 

 produdtions of Scotland, with many carious 

 obfervaticns on them, and in the moft libe^ 

 T^l and friendly manner fubmitted the whol« 

 to my infpedtion and ufe.
