Abstract: Supercritical drying followed by freeze cracking of animal tissue rendered high quality cell surface for gold coating for precise observations under scanning electron microscope. The subpyloric lymph node of Jamieson and Dobson was subjected for this study. The lymph node contained reticular cells which were stellate plates oriented in a uniform direction. Large round macrophages were loosely fixed by the reticular cell processes. The parenchyma of the lymph node was made up of reticular cells, macrophages, lymphocytes, plasma cells and their intermediate types. Macrophages had few long tentacle-like projections that terminated in club shaped cytoplasmic processes. Plasma cells and lymphocytes also remained in the sinuses. The cortex of the node was built up by reticular cells, much smaller than those in the medulla and by densely packed round cells including a few macrophages. The trabeculae and the reticulum of the lymph node parenchyma formed a continuous structure. The continuity of sinus lining cells was confirmed in the present research.
