another on the same tramway, or, that if a 
man’s veins were destroyed his blood should flow 
to his heart through the arteries which are at 
the same time conducting it from his heart. 
And if the sap did descend at all below the scar, 
the tree would increase below the scar, which it 
does not, unless there is an outbreak of branches 
below the scar. 
This is the gentleman who some pages before 
finds the heart-wood so “ filled with secretions ” 
that there is no room even for the upward sap 
to ascend through it. Yet now he makes it 
convey both upward and downward sap, for 
there can be no sap-wood under an old scar. 
But this voluminous compiler of other people’s 
ideas, states all, however incompatible or con¬ 
tradictory one may be to the other, and uses 
either as convenient. Here he makes the growth 
in diameter to be the result of “ the falling sap.” 
A little before he adopts, confidently, the theory 
of Darwin and Du Petit-Thouars. In this there 
is no “ falling sap ” allowed; but a downward
