    I refer the reader to a Text-Book of Physiology, edited by Professor Schafer. Suffice it to say here, that there are various methods of determining the percentage of haemo- globin in the blood, and also the numerical corpuscles —that of Gowers, that of F. Hoppe-Seyler; that of V. Fleischl, and Oliver's improvements on v. Fleischl as adapted by Lovibond, of Tintometer fame, at Salisbury. To be brief— (1) The word normal, as applied to the blood, is used to indicate the average condition of the haemo- globin and corpuscles found by experiment (Oliver) in the blood of a large number of healthy persons. This point was made the 100 on the scale. More extended observations might show that the present 100 is either higher or lower than the average. 100° on the scale corresponds to 15*5 of haemo- globin as determined by chemical analysis. (2) On the hsemoglobinometer, the 100° corre- sponds to 4000 corpuscles per cubic centimetre. (3) The blood ratio is obtained by dividing the haemoglobin number by the number for the corpus- cles—thus (4) Haemoglobin. Corpuscles, or say 1Q{] ~.1 in the case of normal blood. Nevertheless gg- may be normal quite as much as j-gg, the quantity of corpuscular matter varying from individual to individual, being higher in man than in woman, and depending apparently on the size of the
