Publication. 

 There has been no change during the past year in the general 

 poHey affecting publication. The change in plan of printing 

 described in the twenty-seventh annual report continues to 

 prove highly satisfactory. It has resulted in an important 

 reduction in expenditure, and it has made possible a much 

 more prompt and satisfactory distribution of the papers issued. 

 The following list includes both the pubHcations of the past 

 year and a few earlier issues not previously mentioned in 

 reports : —
