the reader. These nals are taken "P pappereiory to a consideration 
of the more special process of the healing art involved in practical 
surgery. ‘These it is not our aaa ee discuss or even touch upon ; 
but what we desire to impress is the necessity of studying the condi- 
tions of nutrition in all its phases of growth and repair, as illustrated 
in the lower forms of life where nature has laid bare the processes for 
our observation 
The study of the development, growth and repair of polypes, a Occ 
and spiders, may seem to have the remotest connection with the domain 
forms imperative with him who would have a wide comprehension of 
her laws. Were we so ‘minded, this train of thought might be very 
pleasantly extended, and we could cite ee our duthor, examples of 
men distinguished in their art, whose eminence is not a little due to 
that broad grasp of organic nbensiouih’ derived from scientific studies 
of this B d. 
But we will quote one passage where Mr. Paget expresses himself o 
this very ‘ior, sk with his usual felicity. It is near the conclusion of 
bs seventh Lectur 
‘**T may seem in hae as in some earlier lectures, to have been discus- 
sing doctrines that can hardly be applicable to our daily practice, and 
to the clearer knowledge of that law, in reliance of whic alone, we 
dare not to practice our profession ; the law, that lost perfection may be 
reepsened by the operation of the powers by which it was once achieved. 
Then, let us not overlook those admirable provisions, 
which we may find in the lives of all that breathe, against injuries that, 
but for these provisions, would too often bring them to their end before 
their appointed time, or leave them mutilated to perish a painful and 
imperfect life. We are not likely to undervalue, or Hs steht of the 
design of all such provisions for our own welfare. But pe better 
appreciate these, if we regard them as only of the same Midd 6 those 
more abundantly supplied to creatures whom we are apt to think j insig- 
nificant: indeed, so abundantly, that, if with a consciousness of the 
facility of self-repair, self-mutilation is commonly resorted to for the 
preservation of life.”—Vol. I, p. 165, 166. 
Pleasant as it would be to discuss these points and. relations further, 
and to follow them in their close conse onan detail to those methods 
of art which belong to the relief of humanity and the restoration of our
