in the urine when any of the three causes mentioned reduce the oxyd- 

 ation in the system to its minimum. In other words, by stopping the 

 combustion that occurs iii the body, diabetes should be produced arti- 

 ficially. 



TEMPERATURE OF THE SEXES. 



At the British Association, 1864, Dr. J. Davy gave the results of 

 some experiments he had made as to the relative temperature of the two 

 sexes. The theory of Aristotle, that a man possessed more warmth 

 than a woman, had been disputed ; and it had been held by some, as 

 the result of modern research, that the temperature of woman was 

 slightly superior to that of men. Notwithstanding this, however, 

 iVoni such observations as he had been able to make, he considered 

 the early opinion the more correct. Taking the average, it appeared 

 that the temperature of males and females was as 10*58 to lOlo. He 

 had more recently made some additional observations, using a ther- 

 mometer of great delicacy, and taking for the purpose of his experi- 

 ments six persons, three men and three women, all in good health. 

 The result was that the temperature in the case of the men varied be- 

 tween 90 and 99^, that of the women was between 975 and 98. An 

 examination of other animals gave a somewhat higher temperature for 

 the male than the female : six fowls showing the proportion of 108'33 

 for the former, to 107 '79 for the latter. 



THE HAIRY MEN OF YESSO. 



At a recent meeting of the Ethnological Society (London) a paper 

 descriptive of the hairy people of the island of Yesso was read by Mr. 

 Martin Wood. Yesso, which is inhabited in the southern portion only 

 by the Japanese, has an infertile soil and dreary climate. Its northern 

 parts are inhabited by the Mosinos, or " all hairy people 11 of the Japan- 

 ese, who number about 100, 000, and dwell principally in two large cities, 

 Mato-mai and Hako-dadi. These people are short, thick-set, and 

 muscular, but clumsy and uncouth in their movements, In appear- 

 ance they are wild and repulsive, in consequence of the enormous 

 amount of hair with which they are covered. The hair on the scalp 

 forms a matted mass of gigantic! size, their beards are long and thick, 

 growing from the greater part of the face, and the whole of their 

 bodies is covered with an extraordinary prolusion of hair. The women 

 stain that part of the face which is covered by the beard in males. 

 The skin, when not bronzed by exposure, is somewhat paler in color 

 than that of the Japanese. These people, though timid from long 

 subjugation to the Japanese, and isolation from the rest of the world, 

 appear intelligent and lively. They have well-developed, prominent 

 foreheads, and dark, expressive eyes. 



PRODUCTION OF THE SEXES AT WILL. 



In the Annual of Scientific Discovery for 18G4, a brief notice was 

 given of the researches and theory of Prof. Thury of Geneva, in respect 

 to the above interesting subject. In a memoir published by M. Thury 

 during the past year, he gives the following summary of his observa- 

 tions and deductions, which bid fair to be of special value to agri- 

 culturalists and stock-growers :
