Dr. O. D. von ENGELN has been promoted to 
an assistant professorship of geography at 
Cornell University. 
Dr. GraHamM Epear has been promoted to 
be associate professor of chemistry at the Uni- 
versity of Virginia. 
Proressor J. L. Giuin, of the State Uni- 
versity of Iowa, who has been teaching sociol- 
ogy there for the past five years, has accepted 
a call to the University of Wisconsin, service 
to begin with the opening of the next school 
year. The work of Professor Gillin at the 
University of Wisconsin will be to teach 
courses in sociology during one semester of 
the year and the remainder of his time will be 
spent as secretary of the department of general 
information and welfare, one of the four de- 
partments in the extension division of the 
university. 
Mr. M. Power, lecturer in mathematics at 
Dublin, has been appointed professor of 
mathematics at Galway.

clined the chair of chemistry at University 
College, London, vacant by the retirement of

DISCUSSION AND CORRESPONDENCE 
THE NATURE OF THE-INHERITANCE OF HORNS 
IN SHEEP 
To our communication in Science of March 
8 Professor Castle has offered* a vigorous 
critique. A wordy continuation of the dis- 
cussion of a matter most of whose points can 
be easily settled by experiments now under 
way would be to imitate the methods of an 
old continent and a past epoch in biology. 
We may add only that the simple Batesonian 
formula which Dr. Castle seems to find suffi- 
cient appears from the context no more fully 
satisfactory to the formulator than to our- 
selves. As to the effect of castration in 
eliminating horns in males, this is, apparently, 
a special result in Merinos and other races

possessing horns typically or prevailingly in 
the males only. Darwin has discussed this 
matter in the “Descent of Man,’ Chap. 
XVII.; and correspondence recently had with 
breeders of Merinos confirms Darwin’s (and 
Castle’s) statements. In Dorset Horns, on the 
other hand, as in reindeer and cattle, castra- 
tion has only a modifying effect. 
Finally, we wish to acknowledge kind sug- 
gestions (in letters) from Professor T. H. 
Morgan and Mr. A. H. Sturtevant, and we 
trust they will publish their formula, which 
differs in several respects from ours. The 
principal difficulty they find with our formula 
is that it does not account for a race in which, 
in successive generations, all males are horned 
and all females are hornless. Such a race of 
Merinos there may be; but there is much evi- 
dence that in many long and carefully bred 
strains of Merinos the standard of hornless- 
ness in the ewes is maintained only by hurry- 
ing the horned ewe lambs to the butcher.

AGRICULTURE IN SCHOOLS 
To tHE Epitor or Science: I note in the 
issue of Science dated April 27, 1912, an 
announcement concerning the signing of the 
Harte bill providing for the establishment of 
a New York State School of Agriculture on 
Long Island. The memorandum by the govy- 
ernor appended to this bill, as quoted in Sct- 
ENCE, might mislead the reader in regard to 
the status of the teaching of agriculture in 
New York. 
The Cortland State Normal School has had 
in operation for nearly a year a course for 
training teachers of agriculture. This course 
is open only to graduates of approved high 
schools who have had practical farm experi- 
ence. The course is for two years’ work. 
It may be that the fact that the governor has 
not been called upon to sign a bill of special 
appropriation for the establishment of this 
course has been the cause of his overlooking it. 
In regard to the high school situation I 
wish to call attention to the fact that seven-
