The goats (three) were milked at definite times twice a day but in 

 addition to this injections of, on the average, 6 c.c. of a j^^-^ solution 

 of adrenalin chloride were made on alternate days after the morning 

 milking, the goats being milked again at an interval of half an hour. 

 On the "normal" days, which alternated with the days on which 

 adrenalin was given, the treatment was exactly the same except that 

 sterilized water was injected in the place of adrenalin. It was so 

 arranged that the day, for the purpose of computing the yield, started 

 with an injection. Table IV below shows the results obtained with the 

 three goats which were treated in this way.

Table V below gives the averages for all these experiments. The 

 fat was estimated on only eight days out of th^ twelve over which the 

 experiment extended, so the figures given for the percentage of fat and 

 amount of fat are the averages of these days only.
