various degrees of richness 
is required by infants, ac-

physical condition. 
This model dairy has a 
large and well designed me-

sanitation is tending. The

tent with the ordinary 
devices, or rather with the

been in habitual use for 
ages, but new methods and 
new ideas are being con- 
tinually developed for the 
large dairy.
