The decrease in the scientific school is due to 
the loss of some eighty students who attended 
under the old land-grant fund régime. The 
freshmen academic class is the smallest of the 
five classes this year, whereas there is an in- 
crease in the scientific school of 16 students over 
last year’s class. 
A CONVENTION of American women propose 
to assemble in Washington on December 14th 
to decide on ways and means of arousing pub- 
lic sentiment in favor of a national university. 
They intend, it is said, to collect the $250,000 
necessary for the erection of an administration 
building, to form the nucleus of the university, 
and hope to be able to lay the corner stone on 
February 22, 1899. 
THE vacant professorship of pathology at 
Cambridge University has been filled by the 
election of Mr. A. A. Kanthack, M.A., of St. 
John’s College, who has acted as deputy for the 
late Professor Roy. Professor Kanthack, as we 
learn from the London Times, has had a distin- 
guished career at the University of London, 
where he has taken with honors the degrees of 
B.A., Bachelor in Surgery, Bachelor in Medi- 
cine, was gold medalist, and proceeded to the 
degree of M.D. in 1892. He has pursued his 
studies at University College, Liverpool ; St. 
Bartholomew’s Hospital, at the Universities of 
Berlin and Cambridge. His introduction to 
Cambridge was in 1891, when he was elected to 
the John Lucas Walter studentship of the value 
of £200, open to all students for the purpose 
of conducting original research in pathology. 
Before that year he had been lecturer in pa- 
thology at St. Bartholomew’s Hospital, medical

tutor at the Royal Infirmary, Liverpool, and 
senior demonstrator in pathology at University 
College, Liverpool. He has devoted many 
years to original research, and was a member 
of the Leprosy Commission in India. He is 
the author of a Manual of Practical Morbid 
Anatomy and of a Handbook of Practical Bac- 
teriology, and also an extensive and frequent 
contributor to the journals of physiology and 
anatomy. 
Dr. THEODORE DES CoupDRES has been pro- 
moted to an associate professorship of physics 
in the University at Gottingen and Dr. Otto 
Knopf to an associate professorship of as- 
tronomy in the University at Jena. Dr. Schmitz- 
Dumond, of Tarand, has been appointed Director 
of the Agricultural Experiment Station to be 
established in Pretoria and Dr. A. Ostroumoff 
to be professor of zoology in the University of 
Kasan. Professor Kuster, of Gottingen, has 
been appointed head of the division for ana- 
lytical, inorganic and physical chemistry in 
the Chemical Institute of the University at 
Breslau. 
DISCUSSION AND CORRESPONDENCE. 
THE MESA ENCANTADA. 
To THE EDITOR OF SCIENCE: I thought that 
Thad said the last word as far as I was con- 
cerned upon the subject of the Mesa Encantada, 
but now that Mr. Hodge’s pictures have ap- 
peared there is one more word to besaid. I 
never dreamed that he or anybody else would 
have mistaken the manifestly modern and 
humanly constructed cairn which he figures, 
and about which so much noise has been made, 
for the cairn-like object of which I spoke. The 
latter is a very different object, and its loca- 
tion gave it some significance, while the former 
has none of any importance. 
The cairn he figures was certainly built by a 
human being on the 23d of July, 1897, and not 
by ghosts.

OBSERVATIONS ON ‘THE PRINCIPLE OF 
IDENTITY.’ 
THE principle that a thing or relation is iden-
