. The American journal of anatomy. cided advantage to inject an organ like the spleen with afluid that will not mix easily with water, and I have tried a variety ofjnixtures of asphalt, turpentine and granules with great success.]lover has already used this mixture in the contracted spleen, andwhat I have found in the oedematous spleen confirms and supplementshis results. When the spleen is distended to its maximum with eitherblood or gelatin the relation of the terminal artery to the pulp isshown beautifully by injecting the turpentine-asphalt solution into theartery. Some granules of carmine should be added to the solution,for they lodge in the fine arterial branches and ampullae, and a few ofthem pass over into the pulp. It is well in making an artificial oedemaof the spleen to inject the gelatin, to which ultramarine blue is added,into the veins. Finally the specimen is hardened in formalin and cut Hoyer, Internat.

The specimens areto be mounted in glycerine. In the sections of such specimens th€veins are found filled with blue granules, the pulp with gelatin andsome blue granules, the terminal arteries v\ith some carmine granulesand the ampullae with asphalt and some carmine granules. As thereis no mixing of the fluid gelatin and the asphalt in the pulp, the asphaltmust take the course of the least resistance from the artery to the Prussian h\\\Q this is often directly through Thomas Zwischen-stiicl-; with asphalt the course is always through the pulp-spaces. In specimens in which little of theasphalt reaches the veins it is foundthat the asphalt passes out into thepulp-spaces from the ampullae, thenpiles up, forming clusters like bunchesof grapes (Text Fig. 1). Each of these• grapes fills a pulp-space. As theclusters spread out the globules of as-phalt often radiate, leaving interven-ing pul
