is the Bromo-clilor. alum, which should be frequently sprinkled from a watering 

 pot through the stalls and passages, a pint to a bucket full of water suffices. 

 The addition of Carbolic acid, i^ oz. to the same measure, may be advanta- 

 geously added. The Bromo-chlor. alum may be obtained, as well as the Golden 

 Seal infusion, at any drug store. 



This disinfectant freely sprinkled into the manure pit will not injure the fer- 

 tilizing properties of that substance. But here Chloride of Lime may also 

 enter. But if Chloride of Lime is too freely used in the stable, the chlorine 

 set at liberty will make the horses cough, and increase the nasal catarrh. 



Before closing we venture the enquiry, may not the glanders (farcin) be 

 closely allied to the malarious contagious ; and, although the glanders is always 

 considered an incurable, fatal disease, might not this same treatment prove that 

 this disease may likewise be cured ? 



Prof. Davidson said he had a series of problems in mensuration 

 similar to those offered on a previous evening ; of these, he pre- 

 sented the following : 



V. Given, the side of a square, to determine, in terms of that 

 side, the consecutive sides of the interior squares which will divide 

 it into a series of hollow squares and a central square, of equal 

 values with each other. 



To divide it into w hollow squares and a central square, call I the 

 given side, a;, ^, etc., the sides next interior, (w-1) and w the last 

 two ; then,

yi. Given the sides of a hollow square, to determine, in terms 

 of those sides, the consecutive sides of the squares which will sub- 

 divide the hollow square into a given number of hollow squares of 

 equal areas with each other. 



Let I' represent the outer, and I the inner sides of the given 

 hollow square ; n the number of hollow squares, x the first side 

 interior to t, y the second, (w-1) and iv the last two ; then,
