BOB VEAL AND THE PUBLIC.

present. Of these three methods the freezing- point seemed to be 
the most sensitive and reliable, and greater attention has been de¬ 
voted to that. The freezing point of each sample was determined 
twice and the average of the two determinations was used in com¬ 
piling the statistics. In comparing the averages of the three 
series of meats there is found to be a difference of from o.io° to 
o.ii° between the bob veal up to 14 days of age and the market 
veal and beef. The results show much closer harmony between 
the market veal and beef than between the market veal and bob 
veal (less than two weeks of age). 
In all three series of meats the averages showed that the 
freezing point of the round was depressed o.oi° to 1 0.02° lower 
than that of the loin. The curious fact was observed that in the 
bob veal up to five days of age this did not hold true. Up to this 
age the loin showed a lower freezing point than did the round, but 
from the age of five to fourteen days the reverse was the rule.

The investigation has been carried on with the idea of obtain¬ 
ing as definite data as possible for differentiating the tissues of 
the bob from older veal.. Thus far in the work no calf older than 
14 days has been used. Although the table shows that the aver¬ 
ages of the experiments indicate quite a satisfactory line of de¬ 
marcation between the younger bob and older veal, there are oc¬ 
casional individual exceptions, and the method as yet cannot, 
therefore, be declared infallible. 
Although a method which would distinguish the tissues of the 
bob from that of the older veal with some degree of positiveness 
would undoubtedly be of great value in aiding the enforcement
