OF Daniel schrumpf who is now undergoing his
trial on the indictment charging him with selling
adueratcd milk, the distinguished chemist, Professor
r. Ogden Doremus, was 10 give his opinion as an ex-
pert the value OF the acomcter used by the Board
Of Health. After a brief cross examination OF DR..
Thomas C. Doremus. the witness stand was occupied
by the Professor who, in response to Mr. Lawrence,
OF counsel for the defence, referred to experience
as a chemist The questions PROFOUND IN this
spect elected the fact, already well known, that the
Professors scientist had been successful Ho
testified that he mad made the subject OF milk a
speciality and lecturcd the subject since $780, and
then went on state that he visited Orange county
number OF times Tor the purpose OF examining milk to
determine its gravity by the Iactometor. Tho exami-
nations which he made demonstrated the fact that the
lactometer not proper indication OF The value OF
milk, as it registered higher quality OF milk when

mentioned, however, that the case having ready

an expert was extremely valuable ~ case OF ms

OF his testimony Dr. Doremus referred 10 SOW
eral authorities who, lie sad, had condemned ihc IN
strument on the ground OF its unreabilty. He fur
ther stated that no deduction could safely be drawn
as to the dulteraton OF milk by from the
ner IN which the milk from The lactometer when
taken out Hc had seen samples OF mix

ecriped characteristic Of aduitera;ed milk In
response TO the inquiry as 10 whether he had made
the tests IN this Case previously made by Dr. White,
that would be willing testify that the fluid tested

Professor porenus then detailed al length the causes
that might tend vary the specific gravity OF ms.
Water and cream make II lighter already inttmatcd,
while cheese and salt reversed this condition.
He considered the laciomcter most erroneous GUIDE,

and opinion that the best method to
determine whether milk was pure impure was by
analys SIS In support OF his saicmcnt that the lac
tometcr was unreliable as test Dr. Doremus read ses-
eral from foreign authors He was then cross
examined by Mr. Prentice, but the Professor NAM

legal assailaDt anu his direct testimony not dis
turbed The further hearing oi the adjourned
until this morning.
