Poisonous properties of the whorled milkweeds Asclepias pumila and AVerticillata vargeyeri . Fig. 5—Sheep 547, at p. m.,September Fig. 6.—Sheep 547, at p. m., September 28. POISONOUS PROPERTIES OF THE WHORLED MILKWEED. 9 of polymorphonuclear leucocytes, occurred in the mucosa of theileum of Sheep 519. In some blood vessels thrombuslike areas oc-curred. Spleen.—This organ was not very abnormal, though the presenceof considerable hemosiderin pigment indicated a possible congestionwhich had subsided. The edematous condition of the Malpighiancorpuscles in the spleen of Sheep 547 indicated a possible congestion. While there was a marked similarity in the tissue changes to thosein animals poisoned by A. galioides, there were certain slight differ-ences, mainly of degree. On the whole the findings in the two sheepexamined agreed very well. TOXIC AND LETHAL DOSAGE. The following table shows the dosage, estimated as green plant, ofA. pumila, which resulted in sickness or death of the sheep. Table 4.—Dosages of A. pumila resulting in sickness or death.
