In No. 7 it is seen puckered, on account of the addition of a thick fluid. The meaning of all the different appearances presented by these Tilarise, obtained from the same patient, will become evident on perusal of a succeeding paragraph.

The blood should be quickly but evenly spread over the covering glass, forming as thin a layer as possible; the cover is then to be quickly inverted (before coagulation sets in) over the mouth of a phial containing a 2 per cent, aqueous solution of this chemical. When the preparation has turned somewhat brown, remove it and place it on a slide, previously charged with a drop of a saturated solution of acetate of potash or soda, when it is ready for mounting, and will keep, I believe, for an indefinite period.
