Hog cholera (pp. 25-31), (illustrated). — An account of this dis- 

 ease and its treatment, compiled in large part from the reports of 

 the Bureau of Animal Industry of the United States Department 

 of Agriculture. As a result of his own investigations the author 

 obtained from diseased animals a bacillus which he regards as iden- 

 tical with that described by Dr. Salmon as the cause of hog cholera, 

 as well as some other bacteria which did not appear to have any con- 

 nectioji with this disease. The bulletin is illustrated by two photo- 

 engravings of the ulcerated caecum of diseased animals.

Meteok(»lo(4ical data, Milton ^A^HITNEY (pp. 35-51). — The me- 

 teorological conditions of the Northern and Southern States, espe- 

 cially the latter, as affecting the growth of staple crops, are discussed. 

 The temperature and moisture of air and soil and their relation to 

 the development of the cotton plant, are especial subjects of the 

 article. For the observation of soil tem])eratures the author has 

 devised a modified form of soil thermometer which records very 

 conveniently the maxinuim and minimum temperatures. In lack 

 of a satisfactory method for determining the amount of moisture 

 in the soil the author has sought and has found, as he thinks, one 

 which will prove satisfactory in the electrical resistance of the soil, 

 which changes with the moistui-e content. Though the details of 

 this method are not completely worked out, it has led to some very 

 interesting observations of physical ]H'oiierties of the soil. 



"One of these is an actual movement of soil particles, due. prob- 

 ably, to changing moisture content; to change of temperature; and 

 possibly, as there is some reason to believe, the changing atmospheric
