for the co-efhcient of digestibility for crude protein in al- 
falfa hay, or 75.6, if we include all the means given. It seems 
probable that the five closely agreeing ones are nearer to 
the truth than the two whose average is ten per cent, below 
the average of the five, and I take it that the 75.6 i^ a less 
representative co-efficient than the 78.4. 
We record in the following table the results obtained 
by pepsin, or artificial digestion, of the first, second, and 
third cuttings of the year 1894; the first cutting of 1895, 
the three cuttings of 1896.
