piously.” Not having yet seen her work I do not know whether 
she has made any reference to the two issues of mine. However 
I have sent her a copy of it, in case she has not seen it, so that 
she may make a use of it if her volume appears as a second 
edition. In my “ Reminiscences of Childhood at Inverkeithing ” 
(p. 59) I said that I had submitted all the evidence on “ the viper 
swallowing her young ” to the publishers of the “ Encyclopaedia 
Britannica,” in December, 1881. On that occasion I wrote as 
follows : — “ In the last edition the subject was not noticed. . . . 
In the forthcoming article on the Reptilia the question it is hoped 
will be settled ‘ once for all,’ so that it may never again come up 
for discussion. If it is again omitted, the article will have left 
out what might be said to be ‘ the most interesting trait in the 
snake family.’ ” — I am, &c., 
THE BRAIN THEORY OF MIND AND MATTER. 
Sir, — Should any of your readers who are interested in the 
“ Brain Theory of Mind and Matter ” care to examine the frame- 
work of propositions on which is based the argument adopted in 
a paper on that subject which appeared in your issue for March 
last, I venture to draw their attention to three of these propo- 
sitions : — 
I. “ All the perceptions ” of man “ have a merely subjective 
existence.” 
This the Authoress of the paper in question sets forth as her 
major premiss, remarking that it is one which “no one has ever 
been able to deny, though many have fancied that they were 
denying or confuting ” it. 
Here it is convenient to note that the minor premiss, “ The 
Brain is a perception of man,” leads us to the conclusion that 
“ the Brain is subjective.”
