should correspond in its dimensions to the aggregate capacity of all the 

 branches; just such an arrangement as may be seen to exist in the vena portae 

 and its tributaries, and farther in the trunk of the tree, which is equal to its 

 roots. Wherefore, if the efferent canals of a fluid must be equal in dimensions 

 to the afferent canals of the same fluid, the chyliferous ducts which Pecquet 

 discovers in the thorax, ought at least to equal the two ureters in dimensions; 

 otherwise they who drink a gallon or more of one of the acidulous waters 

 could not pass off all this fluid in so short a space of time by these vessels into 

 the bladder. And truly, when we see the matter of the urine passing thus 

 copiously through the appropriate channels, I do not see how these veins could 

 preserve their milky colour, and the urine all the while remain without a tinge 

 of whiteness" (pp. 605-606). 



Almost wholly unencumbered by personal comments, the above words of 

 one of the immortals of science are offered in cordial tribute to a valued friend 

 and fruitful seeker who not only has garnered and treasured many precious 

 volumes from seekers of days long passed but has generously entrusted them 

 to others.— May Time deal gently with him and ease the burden of passing 

 years.
