THE DOCTRIXE OF DESCENT. 19 



in the scientific treatment of disease, all this was 

 either carried out or preconceived in Wiirzburg ; and 

 even the celebrated "Cellular Pathology," a course of 

 lectures which he delivered during the first year and 

 a half after quitting Wiirzburg for Berlin, consists 

 only of the collected and matured fruits of which the 

 blossoms are due to Wiirzburg. 



In the autumn of 1856 Virchow left Wurzburg to 

 settle in Berlin. The exchange of a narrow sphere of 

 labours for a wider one, of small means and appliances 

 for greater ones, proved unfavourable in this case, as in 

 many similar cases. Since he has been in Berlin, in a 

 " great Institution," and with luxurious appliances, all 

 the scientific results which Virchow has as yet brought 

 to light are not to be compared, either as to quality or 

 quantity, to the grand and immortal achievements 

 which he himself effected in the little institute of 

 Wurzburg with the scantiest means a new proof of 

 the maxim enunciated by me, and hitherto never con- 

 futed, that " the scientific results of an institute are in 

 inverse proportion to its size." (See " The Aim and 

 Methods of Modern Evolution." *) 



Still more grave is the circumstance that, since 

 settling in Berlin, Virchow has more and more 

 exchanged his theoretical scientific activity for prac-
