took to be an excretory duct going from the glandula renalis, to the epididymis 

 in men, and the ovarium in women ; an account whereof was inserted in the 

 Phil. Trans. N° 385, Mr. Ranby procured a human body, in order to search 

 for it, which he did with all possible diligence. He was not so happy as to dis- 

 cover any duct of this kind ; but having injected the aorta, he found the arteries 

 going to the glandulae renales, disposed as represented in fig. l6, pi. 1. Now 

 whether that branch of the artery, which from the glandulae renales goes down 

 on both sides towards the testicles, without supplying any of the neighbouring 

 parts, might not have been mistaken by the learned anatomist for an excretory 

 duct, all arteries being generally in dead bodies free from blood, and of a 

 whitish colour, Mr. R. will not at present determine, for want of further 

 experiments. 



In the figure, aa represents the right kidney ; bb the left kidney ; cc the 

 descending trunk of the aorta; d the right emulgent artery; e the left emulgent 

 artery ; f the right glandula renalis ; gg the right spermatic artery ; h the left 

 glandula renalis ; ii the left spermatic artery ; kk the ureters. 



aa A smalt artery arising out of the descending trunk of the aorta, a little 

 above the right emulgent artery : it sends two branches bb upwards to supply 

 the right glandula renalis : a third branch cc goes downwards towards the right 

 spermatic artery gg, and then farther in company with the same to the right 

 testicle. 



dd A small artery arising out of the left emulgent artery, near the descending 

 trunk of the aorta, and going directly upwards to the left glandula renalis h. 



ee A small artery arising out of the descending trunk of the aorta, a little 

 below the left emulgent artery. It divides into 2 branches ; one, ff, goes up- 

 wards between the emulgent artery and vein, to the left glandula renalis; the 

 other gg downwards, towards the left spermatic artery, and in company with 

 the same to the left testicle.
