to young to afford any possibility of judging of the presence of 

 tremor. 



As to Alfred N.'s brothers and sisters, Matilda K. (* 1859 'Vs, t '"'/e 

 1894) had tremor in her arms from girlhood. She is said to have been 

 of a lively disposition and »hot a fire». She died at 35 of typhoid 

 fever leaving 3 daughters. All of these are now grown-up, but accor- 

 ding to statement none of them has tremor. 



Alfred N.'s brother, Viktor N. (* 1856 Vs), who is now 63 years 

 old, never trembled before, certainly not as late as two years ago. Of 

 late, however, his right arm has begun to tremble. A specimen of 

 handwriting from October 20th, 1919 shows obvious though very mo- 

 derate tremor. Viktor N, never misused alcohol (in fact hé has made 

 a much more sparing use of it than his brother). None of his two 

 children has shown any signs of tremor. The eldest bom died at the 

 age of about one year. 



Alfred N.'s sister (Alma E. * 1861 "/,), who never showed any 

 trace of tremor herself, has 5 grown-up children, all of whom are free 

 from tremor. 



In this family there have occurred two instances of insanity (with 

 a tendency to suicide, no particulars of the nature of the insanity are 

 known). As for the rest, no mental or nervous diseases are known 

 in the family except that Alfred N. is suffering from a tumour in the 

 spinal cord. Religious brooding is said to have been fairly frequent in 

 the family, but apart from the tremor the family does not differ notably 

 from other country people in the same district. It is worthy of note 

 that the individuals affected with tremor have altogether been of a 

 more lively and »hot-headed» disposition than the other members of 

 the family. They have resembled their trembling fathers both physic- 

 ally and mentally, whereas the others, the unaffected, have resembled 

 their normal (tremorless) mothers. An exception to this rule is 

 Viktor N. With him the tremor did not appear till quite lately, after 

 reaching his 60th year, and the genotypical nature of the affection 

 may consequently be called in question. He does not resemble his 

 trembling father, but his mother, who had no tremor. 



Alcohol does not seem have influenced the tremor in the family. 

 On the one hand the tremor has occurred in women that made no 

 use of alcohol, on the other it has appeared in the males early in youth 

 before they began to take strong drinks. Alfred N.'s tremor has in- 

 creased in the last decade, though he declares that he has totally ab-
