The physical wool characteristics of 268 Iraqi Awassi ewes were studied in 1963, as well as the relationship between some of these traits. The overall average grease fleece weight, clean wool percentage, staple length, fibre length, fibre diameter and degree of crimp were 3·77 lb., 84·85%, 16·47 cm., 17·37 cm., 33·32/t and 4·18 crimps per 2 cm. respectively. These attributes class the Awassi wool as a carpet wool.
Age proved to have no significant effect on any ofthe traits examined. Significant positive correlations were found between grease fleece weight and fibre length and between number of crimps and fibre diameter, while a significant negative correlation was found between clean wool percentage and fibre length.

The rate of uptake and elimination of antimony by both male and female schistosomes has been measured. It has been confirmed that the female schistosome is more susceptible to antimony therapy than the male since she absorbs more drug. The changes in location of the worms and the separation of the sexes following one or more injections of antimony potassium tartrate have been related to the different rates of uptake and elimination of the drug by the two sexes. The suppressive treatment of schistosomiasis is discussed in the light of these observations.

In a retrospective study, four cases of yeast-associated abortion were found among 1,323 bovine abortions during a 5-year period at the New York State College of Veterinary Medicine. Tissues were examined histologically, and results of virological testing and microbiological culture were reviewed. Candida parapsilosis was the only pathogenic agent demonstrated in these four cases. Placental lesions consisted of necrotizing placentitis with large numbers of yeasts within trophoblasts. Secondary fetal infection occurred in all four cases, with histological lesions or isolation of Candida from the lung, liver, intestines, abomasum, and heart. A tentative diagnosis of Candida parapsilosis-induced abortion in cattle can be made on the characteristic intracytoplasmic yeasts in placental trophoblasts.
