174 PARASITES OF MAN 



therefore get a large share. He is improving slowly. Dr 

 Dickinson adds in a postscript, what is still more to the point, 

 that the sausages would be most likely undercooked ; they 

 would be cooked in the frying-pan, and if only brown on the 

 outside would be eaten. It is probable that the outbreak was 

 due therefore to eating underdone meat from this pig, cooked 

 in various ways, and not alone from the ham itself." 



If the facts connected with this outbreak be honestly faced, 

 it must be rendered clear to any unprejudiced observer that 

 Dr W. Lindow Dickinson was the first person to observe, 

 recognise, and treat the Trichina disorder in this country. No 

 other English, Scotch, or Irish physician has encountered any 

 similar case. If I lay stress upon this fact it is because I 

 have learned from Dr Dickinson that another person has 

 asserted priority in this relation. Sir Dominic Corrigan is 

 stated to have told a gentleman in the House of Commons, 

 "that he had often met with trichiniasis in his practice in 

 Dublin," further averring that the disease " was quite common 

 in many parts of Ireland." If Sir D. Corrigan merely desired 

 it to be understood that he had repeatedly encountered the 

 Trichina at post-mortem examinations, then there is nothing 

 surprising in his statement, but if, on the other hand, the dis- 

 ease itself has been frequently recognised in the living Irish 

 human subject, one can only express astonishment that hitherto 

 no single instance of the kind appears to have been recorded 

 either in the public or professional journals.
