THE LIFE OF KARL WILHELM SCHEELE XV 



he commences to generalise from unsound data or false 

 premises. Not only did he, at this period, devote his spare 

 time to the chemical examination of the different substances 

 with which his calling brought him in daily contact, but he 

 largely encroached on the hours which ordinary persons would 

 devote to sleep, for the purpose of carrying on these investiga- 

 tions, and making an exhaustive study of the then standard 

 works on chemistry and pharmacy. No doubt this self- 

 imposed Spartan course of study, coupled with privation, told 

 upon his constitution in after years, and contributed in no 

 small measure to his early death. Not that it ceased after 

 this period ; he continued his Herculean labours and studies 

 up to within a few days of his death. 



In 1765 he removed from Gothenburg to Malmo, where 

 he resided for five years with a pharmacist named Kailstrom. 

 From Malmo he removed to Stockholm, to one Scharenberg, 

 also a pharmacist. It was here, at Stockholm, whilst with 

 this same Scharenberg, that he wrote out a paper giving details 

 of his experiments on cream of tartar, from which, as will be 

 seen in the sequel, he isolated tartaric acid, and he sent this 

 paper to Bergmann, the then leading chemist of Sweden. Un- 

 fortunately, somehow or other, Bergmann overlooked it, and 

 for a time Scheele was not inclined to intrude himself further 

 on the notice of that man of science. Eventually, however, 

 and mainly through the good influences of Eetzius, it was 

 communicated to the Academy of Sciences at Stockholm. 



In 1771 his Essay on Fluor Spar was published. 



In 1773 he left Stockholm for Upsala, where he became 

 acquainted with Gahn, the Assessor of Mines at Fahlun, and 

 through his good graces was at last presented to Bergmann, 

 and it has well been said that the greatest of Bergmann's 

 discoveries was the discovery of Scheele. 



Bergmann became not only the patron but also the friend
