GENERAL TABLE. 



Mus norvegicus var. albus (albino). The records are grouped according to sex, 

 and in the case of each sex, every record carries its own serial number. In the 

 present table, the records are arranged according to body-weight in two series, 

 Series l, normal, 458 males, 215 females. Series 2, injected with lecithin (Hatai 

 '03), 4 males, 3 females. Both series were used in forming the special tables. 

 If new observations are published in the future, each new record will bear its 

 own serial number. In case series are to be formed for any purpose which 

 involves the use of new records combined with those previously published, 

 the latter will always bear the serial number given them when they were first 

 printed. By this device, it is hoped that confusion between the new and old 

 records may be avoided.
