dated 21ft February 174'?, has affixed to it the refpeeT:able names Account of 



of MUSCHENBROEK, OsTERDYK, Van RoYEN, AlBINUSj GaU- 



Bius, &c. He left Leyden, after having vifited fome part of 

 the north of Germany, about the end of the year 1 744. 



Soon after his return from the Continent, fome circumflances 

 induced Dr Roebuck to fettle, as a phyfician, at Birminghain. 

 Before that time, Birmingham had begun to make a rapid pro- 

 grefs in arts, manufacflures, and population, and, by the death, 

 of an aged phyfician, an opening was prefented to him, which 

 afforded an immediate profpecfl of encouragement in that line. 

 His education, talents, and interefting manners, were well cal- 

 culated to promote his fuccefs as a phyfician. He accordingly 

 met there, at a period more early than he expecfled, with great, 

 encouragement, and was foon diflinguifhed, in that town, and 

 the country adjacent, for his ikill, integrity, and charitable com- 

 pafilon, in the difcharge of the duties of his profefiion. 



It appeared, however, foon after his refidence was fixed at 

 Birmingham, that his. ftudies and indaftry were turned to other 

 objedls befides thofe of his profeffion. Strongly attached to 

 the rifin^ fcience of chemiflry, he conceived high views of ex- 

 tending its ufefulnefs, and of rendering it fubfervient to the 

 improvement of arts and manufactures. With this view,. he fit- 

 ted up a. fmall laboratory in. his own houfe, in which he fpent 

 every moment of his time, which, he could fpare from the du- 

 ties of his profefiion. There, in the true fpirit of his great ma- 

 iler, Lord Bacon, of whofe philofophy he was a great admirer, 

 he carried on various chemical procefiTes of great importance, 

 and laid the foundation of his future projeifls, on well tried and 

 well digefted experiments*.
