CEREBRAL TISSUES of DOGS.
DR.. " Gilman Thompson a professor in the New
York Medical College. has lately made some cAp''i
nents in brain grating with success. Attempts nav
been made to graft nearly all the different TISSUES Vi w
body skin, bone. teeth, muscles nerves. Ee'us' 800
mucous membrane. etc. have all been gf"'leu WIN

not heretofore been performed WIN the eAocP''c"

little nfactica value. They are, however Oh sIc"'
scientific interest in demonstrating the relative vaty

accompany desenerativc processes
When Tribune reporter called at the nome Oh rro'
fes,or Gilman Thompson yesterday the professor was
NOT at home. but Dr. Charles Henry Brown. OF No -
West Forty -nftlIst checrully gave the reporter al
account Of recent experiments
Yes he said at first two large dogs were
trephined over the right Occiptal region Inc Dalh
tissue was cXciScd in one piece ana cAchahE""' t0
niece from dog-lct Us call him A-was put into the
opening in the brain OF dog b, and vice versa oh
the third day both dogs were killed. and che trans
panted pieces Of brain tissue looked normal ana ID
each case they were adhercDt and firmly covered
with fhrou oxidation that it was impossible 10 pun
them on wlth forccps without aceration' IouaI onnu

Dr. Brown then read a letter which DE- Thompson
had written fsr his medical publication relating to the
most successful experiment. 1t read as follows
A large dog was secured. \ halfnch trephlne
was used and button of bone was cut nearly throIsH
over the ft occipal region. leaving small attached
margin 80 that the button could be elevated ana teh
depressed like n tnpdOor. Through the opening tio
brain tissue was removed. \ cat was simultaneously
