Achylia Gastrica--This is frequently the terminal stage of chronic gastritis. There is an entire absence of hydrochloric acid, and a very low total acidity. A small amount of lactic acid may be present. The motility of the stomach is fairly good. This condition is often associated with gastric carcinoma and pernicious anemia.

The slide and cover slip must be absolutely clean to enable the blood to spread in a very thin layer. Note size, shape and color of red corpuscles. Note the leucocytes and the ameboid movements of the polynuclear variety. Note the fibrin. One may examine fresh blood for the malarial parasite, embryos of filaria sanguinis hominis and the trypanosoma gambiense. Haemoglobin--For an accurate estimation use the Sahli apparatus. The haemoglobin is expressed in percentage, 100 per cent being considered as the normal. Estimation of Haemoglobin--By the Use of the Sahli Hcemometer.--Fill the graduated tube to mark 10 with N/10 hydrochloric acid. Fill the pipette up to the mark 20 cu. m.m. with blood. This is quickly discharged into the N/10 hydrochloric solution. Shake and let stand for one minute. Now dilute with water until color matches that of the standard solution.
