Among the 500 observations recorded above there are 400 which 

 were made on both sides of 200 bodies (128 male and 72 female). 

 It is worth while to compare the series.

On the whole the two series do not differ very materially, with 

 the exception of one point. The smaller series, in which both sides 

 of every subject were examined shows that the left sides of women 

 furnish decidedly the largest proportion of abnormal origins. It is 

 clear that my female series is too small to give the true average. 



The ßelation of the Recurrent Laryngeal Nerve to the 

 Inferior Thyroid Artery. 

 The first volume of the Anatomischer Anzeiger contains a small 

 series of observations on this point, which is not included in the
