VIII THE EXCRETION OF URINE 419 vessels, and relation to the Malpighian corpuscles, which he tookto be simple vascular tufts, distinct from the dilatations of theducts. Bowman (1842) first recognised the fundamental factthat the vascular glomeruli are enclosed in the spherical dilatationswhich he designated capsules—in other words, that the Malpighiancorpuscles are terminal expansions of the uriniferous tubules,embracing a vascular glomerulus (Fig. 108). The Malpighian corpuscles and their relation to the afferentand efferent blood-vessels are plainly seen on injecting the vessels,.
