■which is responsible for about one-seventh, if not more, of the 

 deaths of our population. Dare we hope that further ex- 

 perimental research may ultimately arrive at some method of 

 diminishing this frightful annual loss? Shall we get a clearer 

 insight into what we term the law of heredity ? Supposing 

 infection ab utero, has it no limiting period of incubation ? must all 

 ages bend to its presence ? I am not aware whether the organisms 

 found in fowl cholera have as yet been discovered in the newly laid 

 egg. The answ 7 er can only come from careful experimental inquiry. 

 In it lies the hope of discovering the means of immunity, and I 

 trust that, in spite of hasty and prejudiced legislation, such 

 researches may yet be made in this country, as will conduce, not 

 alone in this, but in other maladies, to the future welfare of both 

 man and beast, so that we may say in the words of the poet : — 



" 'Tis worth a wise man's best of life, 

 'Tis worth a thousand years of strife, 

 If thou canst lessen, but by one, 

 The countless ills beneath the sun."]
