took a fhare, and wrote feveral pieces, in which the grave and 

 the ludicrous were both occaGonally employed. None of thefe 

 pieces have been publifhed ; but the plan that was in the end

From the time of fixing his refidence in Edinburgh, Dr Hut-

 the world by the three volumes of phyfical and literary efTays fo 

 much and fo juftly efteemed *. In that fociety he read feveral 

 papers ; but it was during the time that elapfed between the 

 publication of the laft of the volumes juft mentioned, and the 

 incorporation of the Philofophical into the Royal Society of 

 Edinburgh ; which laft was eftablifhed by a royal charter in 1 783. 

 None of thefe papers have been publifhed, except one in the 

 fecond volume of the Tranfaclions of the Royal Society, ** On cer-

 yet a very young man, and making excursions on foot through 

 the different counties of England, till that which we are now 

 arrived at, a period of about thirty years, he had never ceafed to 

 fludy the natural hiftory of the globe, with a view of afcertain-

 From the year 1777^0 1782, the meetings of the Society were pretty regular, much 

 owing to the zeal of Lord Kames. Mr Maclaurin may be regarded as the 

 founder of this Society.
