The advantages of the method are many ; it is extremely rapid, samples can be comfortably analysed in 

 five minutes, with reliable results. It can be recommended to public analysts to sort out milk samples which 

 may be sent them. The trouble of making a fat estimation by this method is very little, if any, more trouble 

 than weighing out of the milk, etc., for the determination of total solids. By the determination of the density, 

 also, the solids not fat can be estimated by the formula o Hehner and Ricnmond (The Analyst, xiii., 32), or 

 the milk scale (The Analyst, xiii., 65), with sufficient exactitude to decide whether the milk is undoubtedly 

 genuine or suspicious. A great advantage is obtained by this method, as the necessary further determination 

 can at once be proceeded with while the milk is fresh. For commercial purposes it is also sufficient ; the cost 

 of reagents is small, and the use of ether with its objections is avoided. The error, with care, does not exceed o.i 

 per cent. Machines to be driven at a moderate speed only.
