22 HISTORICAL INTRODUCTION. 



volume of the Afhandlingar, published in 1818, 

 is almost filled with papers on the same subject 

 by Berzelius. His papers on the subject in that 

 volume, amounting to nine and all of them, 

 especially the two last, are exceedingly important. 

 The whole of "these papers have appeared in the 

 German Journals; and the greater number of 

 them in the French and British Journals. In 

 the 6th volume of the Afhandlingar, and in 

 several of the latter volumes of the Memoires of 

 the Stockholm Academy, this indefatigable ex- 

 perimenter has prosecuted the subject still far- 

 ther. To him we are indebted for a much 

 greater number of accurate analyses than to the 

 whole chemical world put together. It is quite 

 needless to observe how much the labours of 

 Berzelius have contributed to the establishment 

 of the atomic theory, and the immense progress 

 which the science has in consequence made. 

 In fact, we may almost say that it was by him 

 that the theory was established. His analyses, 

 in point of accuracy, infinitely surpass all those 

 which had preceded him. He has embraced 

 every department of chemistry with equal ardour, 

 and every department lies under the deepest 

 obligations to his indefatigable industry and pro- 

 found sagacity.
