A careful examination of all the pus-corpusclespresent in a given case will invariably show how much the constitutionhas been impaired by disease; the paler the pus-corpuscles the more un-favorable the prognosis, and, therefore, the worse the constitution of thepatient at the time of examination. 1.

Different formations, such as pus-corpuscles and fat-globules, may be seen upon them in small numbers,but are accidental and do not change the diagnosis.

When very delicate and pale, it has been advised to color the casts bythe addition of a drop of iodine-iodide of potash solution (iodine, 1 part;iodide of potash, 2 parts; water, 300 parts) upon the slide, which willstain them yellow and render them more distinct. This is rarely neces-
