XVIII Proceedings of the Association of American Anatomists 
ON THE ARTERIA RECTA) OF THE MAMMALIAN KIDNEY. By G. Cart 
Huser. University of Michigan. 
In corrosion preparations of the blood-vessels of the kidney of the dog, 
eat, rabbit, and guinea-pig it was observed that all the straight arterioles 
and capillaries passing to the medulla were branches of efferent vessels 
of the glomeruli. 
ON THE STRUCTURE OF THE AMPHIBIAN AND REPTILIAN KIDNEY. 
By G. Cart Huser and WArD J. MACNEAL. University of Michigan. 
The presentation consisted in a brief description of models of the 
uriniferous tubules of the frog and the turtle, Chrysemys marginata. The 
models were made after the Born method of wax-plate reconstruction. 
The duct systems of these kidneys were studied by the corrosion method. 
ON A MODIFICATION OF THE OBREGIA-GULLAND SUGAR-DEXTRIN 
METHOD. By G. Cart Huser and CLARENCE SNow. University of 
Michigan.
