formula E indicates that the true molars have four, three and 
three tubercles respectively, and that the inferior true molars have 
four each. This represents the extreme common among the 
higher races. l 
For clearer understanding of these characters they are ar- 
ranged in the form of a table. Only the principal races are rep- 
resented, and hybrids, when determinable, are omitted! The 
characters of the superior molar teeth only are referred to. These 
are classified under four heads, viz., first, tubercles 4—4—4; 
second, tubercles 4—4—3 34 or 4—3 14—31; third, tubercles 
4—3 14 —3 ; fourth, tubercles 4—3—3. As already remarked, the 
extreme types of the series give the most precise indications of 
race, while the intermediate conditions have a various range. 
In the first table the most obvious results are, that only the
