as low as Cologue. From Duffldorp 1 went to Xanten, and from 
thence reached Holland ; few parts of which I left unvifited. 
I efteem my meeting with doctor Pallas, at the Hague, a 
momentous affair, for it gave rife to my Synop/is of Quadrupeds, 
and the fecond edition, under the name of the Hiftory of Quadru- 
peds; a work received by the naturalifts of different parts of 
Eurcpe in a manner uncommonly favorable. ‘This and the fol- 
lowing year, doctor Pallas refided at the Hague. From conge- 
niality of difpofition we foon became ftrongly attached. Our 
converfation rolled chiefly on natural hiftery, and, as we were 
both enthufiaftic admirers of our great Ray, I propofed his un- 
dertaking a hiftory of quadrupeds on the fyftem of our illuf- 
trious countryman a little reformed. He affented to my plan, 
and, on Fanuary the 18th, 1766, he wrote to me a long letter, 
in which he fent an outline of his defien, and his refolution to 
purfue it with all the expedition confiftent with his other en- 
gagements. But this work was fated to be accomplifhed by 
an inferior genius. In the next year he returned to Berlin, his 
native place; his abilities began to be highly celebrated; his 
fame reached the court of Peter/burgh, and the emprefs, not 
more to her own honor than that of my friend, invited him 
into her fervice, and in 1768 placed him at the head of one of 
the philofophical expeditions projected for difcovery in the moift 
diftant parts of her vaft dominions. This was an expedition 
worthy of Pallas; it began in June 1768, and was concluded 
on the 3oth of Zuly 1774. It unfolded all his great talents, 
and eftablifhed his fame equal at left to the greateft philofophers 
of the age. He was loft to me during that period. On hear- 
ing of his return I wrote to him at Peterfburgh, and fent to 
him 
Docror Patras.
