    APPENDIX. Paraffin C. Solid paraffin 30 grms. Cocoa butter 20 gi-ms. Spermaceti 10 grms. This is a moderately tard imbedding mixture, soluble in -carbolic acid and turpentine. Paraflin D. Solid paraffin 20 grms. Cocoa butter 10 grms. Spermaceti 10 grms. This is a harder miftture, aleo soluble in carbolic acid and turpentine. Spermaceti and Castor OH. Spermaceti 40 grm. Castor oil 10 grm. [An excellent mixture is the following : Paraffin 2 parts, Vaseline 1 part. This is transparent enough to enable the position of the imbedded tissue to be made out; it penetrates tissues well, is consistent, cuts easily, and is readily soluble in carbolic acid and turpentine. If a harder imbedding material is required a little more paraffin may be added.] Staining. Hsematoxylin. (Prepared according to Kleinenberg.) 1. Take crystallized calcium chloride and add it in excess to 70 per cent, alcohol; shake well and let it stand. Draw off the satiu-ated solution and add alum to excess, shake up and let stand. Pilter.
