The active changes of indentation and pi'otrusion have usuallv disa])peared in a large nnniber of corpnscles, l)v the time paling- has snfificieutly progressed to render the interior structure visible. As before stated, some corpuscles permanently retain scalloped and knobbed forms, while the majority are finally more or less rounded olf; bnt the i)lay of changing shape of many corpuscles is going on at the same time that this net-work is seen. After a while, further '' paling stops, and the net-work structure of all corpuscles which show it, remains visible indefinitely long. Blood-coi-puscles, from hemorrhage in the bladder, in the urine of the late Di-. H****y, preserved with some bi(;hromate of potash, still show the net-work after three years. Specimens of blood taken from different individuals exhibited all the phenomena described, but with some slight differences among each other as to the order and time of appearance. A 40 per cent, saturated solution of bichromate of potash, admixed with the blood, was found entirely satisfactory for the demonstration of all the phenomena; and some variation of strength— /. ^., between the limits of a 35 per cent, and a 50 per cent, saturated solution—made no appreciable difference. Of other solutions of bichromate of potash, it is sufficient to state the following: With a 30 per cent, satui-ated solution, the phenomena are also to be seen, but appear more slowly, and quite a number of corpuscles usually remain more or less unpaled. With a 20 per cent, satnrated solution, the changes proceed still more slowly; comparatively few indentations occui*; the net-work of the majority of corpuscles is visible after the lapse of twenty-foiu- hours, l^ut many remain entirely unaffected. With a 10 per cent, saturated solution, vacuolation appears, also a little changing indentation and protrusion, but not suf- ficient paling to render the net-work visible even after several days. With a GO per cent, saturated solution, the majority of the corpuscles had already become pale by the time the specimen was in place for examination. Some showed interior net-work, some only double-contoured rings. Protrusions were seen,](https://iiif.wellcomecollection.org/image/b21219163_0097.jp2/full/800%2C/0/default.jpg)
