Clinically healthy Korean adult cattle (20 females and 20 males) were selected and subjected to the experiments on the determination of erythrocytes and total leukocytes values at the stages of pre and post-slaughting. Throughout the studies the following results were obtained. 1. The erythrocytes values, at the stage of the pre-slaughter, of females and males were $6.070{\times}10^6/cmm$ and $6.175{\times}10^6/cmm$ respectively. In the case of post-slaughter stage, $7.780{\times}10^6/cmm$ and $7.705{\times}10^6/cmm$ were obtained for female and male respectively. In comparison on the values of erythrocytes between pre and post-slauglnter stages, the mean value of the latter has been increased significantly. 2. The total leukocytes value, at the stage of the pre-slaughter of females and males were 9,525/cmm and 9,630/cmm respectively. In the case of post-slaughter stage, 7,545/cmm and 7,510/cmm were obtained for females and males respectively. In comparison on the values of total leukocytes between pre and post-slaughter stages, the mean value of the latter has been decreased significantly.

Casting specimens of portal system and hepatic vein system in livers were made by injection of vinylite into the portal vein and postcava in 20 adult dogs. The author classificated the ramification of portal system and hepatic vein system. The results obtained were summerized as follows: 1. Portal system in livers were divided into left and right trunks. The left trunk subdivided into papillary process (caudate lobe,) left medial lobe, left lateral lobe, quadrate lobe and right medial lobe rami. The right trunk were subdivided into right lateral lobe and caudate proccss(caudate lobe.) 2. The lateral superior and medial inferior rami of portal system in left lateral lobe were subdivided 1 or 2 branches from left trunk. 3. The lateral superior ramus of portal system in left medial lobe did not appeared in 40% of the cases examined. 4. Portal system in quadrate lobe were subdivided 1-3 branches from left trunk, 5. Portol system in right medial lobe rami were relatively simple in ramification. 6. The lateral superior and medial inferior rami of portal system in right lateral lobe were subdivided 1 or 2 branches from right trunk. 7. Hepatic vein system of left lateral, left medial, quadrate and right medial lobe rami were originated from same ramus divided from the postcava in all cases. 8. Hepatic vein system of left and right rami in right medial lobe were divided from postcava.

Studies were carried out to establish number of erythrocytes, leucocytes, and percentage of reticulocytes and hemoglobin on the growing chicken of Leghorn. 1. The number of erythrocytes were increased from 20 days to 30 days after hatching, and maximum value was observed at the day of hatching. 2. The percentage of reticulocytes were decreased with growing and developing of chicken.
