White blood cells, epithelial cells, and protein in the irrigational fluid from cow uterus increased at 2 to 4 months of pregnancy.
Major protein fractions of uterine milk from cow at 2 to 5 months of pregnancy consisted of albumin, al, a2, β- and γ-globumins, and these fractions are approximately the same as that of serum. Moreover immoelectrophoretic studies revealed the presence of 5 precipitation lines.
Before 5 months of pregnancy the electropholetic patterns of the uterine milk were similar to that of the serum, and after 7 to 9 months of pregnancy albumin, _α2- and β-globulin decreased in the protein.

Turkey semen, diluted with 7% glucose egg-yolk solution and quickly frozed with liquid nitrogen was stored at-196°C for the periods of 70 to 440 days. The motility of the spermatozoa and the percentage occurrence of abnormal spermatozoa chiefly the neck-bending spermatozoa in the thawed semen were studied in relation to the lengths of storing period.
The following results were obtained.
1. The percentage of motile spermatozoa (over ?? ) in the semen thawed after the different storing periods of 70, 104, 122, 226 (a, b), 367, 411 and 440 days was 73.8% on the average, ranging from 50 to 90%, and it did not appear that the spermatozoa motility was adversely affected by the long-term preservation.
2. In the same thawed semen as above, the percentage of neck-bending spermatozoa averaged 17.1%, ranging between 14.4 and 21.1%. There was not observed a tendency that this percentage increased with the length of storing period.
