works was one of the richest and most valuable in Sweden. He also had 
the advantage of receiving the immediate instructions of his protestor, 
and of being able to take his advice in all difficult cases. Upon the 
whole, Celsius treated him with paternal care, and gave him 
various proofs of his benign favour on many subsequent occasions. 
In return for such kindness, Linnaeus, among all his patrons cherished 
most the memory of this venerable man. He never spoke of him 
without expressing his reverence and gratitude. Celsius died, like 
Linnaeus, in the full enjoyment of his celebrity, on the twenty-fourth 
of June, 1756, at the advanced age of seventy-six years, and found al- 
ways among his academical colleagues in his former pupil the warmest 
and most grateful of friends. 
Tournee t was the only botanical author to whom Linnaeus 
stood thus far indebted for the greater and more solid part of his know- 
ledge. The sovereign empire which that great writer had acquired in 
botany, since the latter end of the last century, began now to totter. 
The young student at Upsal conceived the idea of creating a new 
system of doarine. It was a Frenchman who inspired him with this 
new thought. It was Vaillant, one of the most penetrating bo- 
tanists, who died too soon for his scientific fame, and for the botanical 
discoveries and elucidations which he gave as demonstrator of the 
royal botanical garden at Paris , where he departed life in the year 
1722. We shall have occasion, in the course of this work, to make 
more ample mention of him.

various parts and properties of the plants, from their fruits, from the 
number of the petals of their flowers and blossoms, See. Till then,
