depth was 36 degrees. It is a curious fact in connection with 
such basins as this that the water of the bottom of them is of 
exactly the same temperature as that which runs over the topof

— The Division of Entomology, Department of Agriculture, 
has begun the publication of a Bulletin. No. 1 contains reports 
of experiments, chiefly with kerosene, upon the insects injuriously 
affecting the orange tree and the cotton plant, made under direc- 
tion of the entomologist, Professor Riley. The second number 
includes the report by Mr. Lawrence Bruner, of his observations 
upon the distribution of the Rocky Mountain locust, in British 
North America, in 1882, in the region of Fort McLeod, and the 
Cypress hills and neighboring regions. Mr. S. A. Forbes com 
tributes memoranda of experiments relating to the use of kero- 
sene emulsions on chinch bugs. The correspondence contains 
items of considerable entomological interest. 
— An interesting case of breeding is reported from ee 
viz., the fruitful pairing at Halle, of a Gayal bull from India with 
a cow of the long-horned African Zebu race, from the Soudan. 
The latter belongs to the oldest races of horned cattle, whose 
forms, as the figures on ancient Egyptian monuments witness, 
ave remained the same for thousands of years. The result shows
