The foolish brother acquires three magical horses and uses them to reach a princess atop a glass hill for three times. ATU 530A, "The Pig With Golden Bristles": as a continuation of the story of The Glass Mountain, after the wedding, the tsar/king sends his sons-in-law on a quest for some creatures with marvellous attributes. The older brothers want to go on the quest to impress their father-in-law and further humiliate their youngest brother. ATU 550, "The Golden Bird": a king sends his three sons to find the golden bird and bring it home. The older ones fail, but the youngest is successful, capturing the bird and a horse and bringing with him a maiden as his wife. Spurred by intense jealousy, they murder their sibling or toss them in a ditch and take the prizes of the quest for themselves. ATU 551, "The Water of Life": a king is dying or blind, so he sends his sons for a magical cure (a magical bird, the water of life, etc. ), which can only be found in a distant realm, in the hands of a princess or maiden. The youngest is successful and returns with the prize, but his brothers drop him in a ditch. The youngest prince survives and returns incognito to the city. The foreign maiden comes after the person who stole her property. ATU 554, "The Grateful Animals": in some variants, the youngest brother protects or helps three animals of different species, much to his brothers chagrin, who wanted to hunt them.
Lymphocytosis is an increase in the number or proportion of lymphocytes in the blood. Absolute lymphocytosis is the condition where there is an increase in the lymphocyte count beyond the normal range while relative lymphocytosis refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range. In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 109/L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds 40%, it is recognized as relative lymphocytosis. Causes
Lymphocytosis is a feature of infection, particularly in children. In the elderly, lymphoproliferative disorders, including chronic lymphocytic leukemia and lymphomas, often present with lymphadenopathy and a lymphocytosis.Causes of absolute lymphocytosis include:

acute viral infections, such as infectious mononucleosis (glandular fever), hepatitis and Cytomegalovirus infection
other acute infections such as pertussis
some protozoal infections, such as toxoplasmosis and American trypanosomiasis (Chagas disease)
chronic intracellular bacterial infections such as tuberculosis or brucellosis
chronic lymphocytic leukemia
acute lymphoblastic leukemia
lymphoma
post-splenectomy state
CARD11-related congenital B cell lymphocytosis (rare, also known as BENTA disease)Causes of relative lymphocytosis include:

age less than 2 years;
acute viral infections;
connective tissue diseases,
thyrotoxicosis,
Addisons disease,
splenomegaly with splenic sequestration of granulocytes. Diagnosis
Lymphocytosis is usually detected when a complete blood count is obtained. If not provided the lymphocyte count can be calculated by multiplying the total white blood cell (WBC) count by the percentage of lymphocytes found in the differential count.
