I recall the case of a man of 32, a big, stalwart fellow, who came to me about two years ago with a very severe case of combined stammering and stuttering.  He made his plans to place himself under my care but before getting back, fell a victim to his inordinate appetite for drink and was laid up for a week.  His wife wrote me the circumstances, told me it had been going on for nine years and that all efforts to eradicate the appetite had failed.  I immediately advised her that I considered his case incurable and could not accept him for treatment.  In such cases, a cure is built upon too shallow and uncertain a foundation to offer any hope of being permanent.

Below normal intelligence:  There is another incurable case which must be included if we are to complete this list of the incurable forms of speech impediments.  That is the case of the stammerer who is of below normal intelligence.  These cases are very rare and I do not recall but four instances where a case has been diagnosed as incurable on account of the lack of intelligence.  This is a direct refutation of the statement that stammerers are naturally below normal in mental ability.  Out of more than twenty-six years’ experience in meeting stammerers by the thousands, I can say most emphatically that stammerers as a class are not naturally below normal intelligence or mental power, save as their trouble may have affected their concentration or will-power.

The lackadaisical:  The last and largest class of incurable cases of stammering are those who will not make the effort to be cured.  These are the spineless, the unsure, the cowards, who are afraid to try anything for fear it will not be successful.

They are usually afflicted with a malady worse than stammering or stuttering—­“indecision”—­a malady for which science has found no remedy.  Knowing the dire results of continued stammering, still they stammer.  Reason fails to move them to the necessary effort.  Common sense makes no appeal.  Well, indeed, in such cases, may we paraphrase the words of Dr. Russell H. Conwell and say: 

“There is nothing in the world that can prevent you from being cured of stammering but yourself.  Neither heredity, environment or any of the obstacles superimposed by man can keep you from marching straight through to a cure if you are guided by a firm, driving determination and have health and normal intelligence.”

These seven classes of incurable cases complete the list.  And the number of such cases, all taken together, is so small as to be almost out of consideration.  For, out of a thousand cases of stuttering and stammering examined, I find but 2 per cent. with organic defects or of an incurable nature.  In other words, 98 per cent. can be completely and permanently cured.
