digestible matter taken as 100, including in that term the ‘oil, 
carbohydrates, and albuminoids. There is also given the average 
of the salt-bushes properly so called, omitting the blue-bush, as the 
analysis was made on a specimen at a different and imperfect stage 
of growth, and the cotton-bush, as it is a plant of an entirely 
different character. 
€ great difference between the salt-bushes and European 
fodders is thus shown conspicuously, and the former are placed 
entirely by themselves, whilst the cotton-bush, as far as the points 
considered are concerned, ranges itself with the latter.

These plants being chiefly used for the pasturage of sheep, we 
may glance at what effects might be expected to take place on the 
annals, for there seems little doubt that changes in them must 
Cecur from a diet so very different to that on which they have 
been bred from immemorial time in Europe. Youatt, after 
Speaking of the effect of climate on sheep and their wool, says :— 
Wool is formed must decrease like every other when sufficient 
nourishment is not afforded.” i
