of his deep respect and sincere admiration, by the 

 author." As Professor Virchow has travelled over 

 much of the ground that had been previously 

 cultivated by Goodsir, it is no less remarkable than 

 disappointing to find in Virchow's volume of 433 

 pages but one reference to Goodsir, and that in con-

 be more fairly ascribed to Dr. Martin Barry. This is 

 scanty civility to a scientific confrere whom he has 

 called " one of the most acute observers of cell-life," — 

 one whose labours he has availed himself of, and whose 

 opinions and words he has occasionally adopted.

 the Glanduloe Aggregatae of the Ileum in Fever," 

 Goodsir (vol. ii. p. 377) describes these changes to be 

 of the following nature — viz. " the development of cells 

 within the constituent vesicles of the patches to such 

 an extent as at last to burst them, or cause their 

 solution ; the continued increase in the number of the 

 cells proceeding from as many centres as there are 

 vesicles in the path ; the conglomeration of the whole 

 into one mass above the sub-mucous and under the 

 mucous membrane, the distension of the latter, and

 same volume, Goodsir, speaking of simple or developed 

 cells holding certain relations to one centra] or capital 

 cell, says — " Ii would appear thai from this central 

 cell all the other cells of its departmenl derive their
