familiar ground, for in agropyrum he may recognize the old triticum 

 repcns or couch grass of our ancestors, whilst bael fruit, arnica flowers, 

 orindelia robusta, datura leaves and seeds, kara and oleum gynocardise 

 or chaulmoogra oil present no difficulty. The cotton root bark, gossy- 

 pii radicis cortex, is probably introduced as a substitute for ergot, as it 

 has been found useful in the same class of cases as that drug. Sesame 

 oil is a useful solvent, and may be employed in making the official lini- 

 ments, ointments, and plasters for which olive oil is usually employed. 

 Pecrohiza and olive bark will probably puzzle the most enthusiastic 

 student of materia medica who will consult the text-books in vain for 

 a description of their virtues. 



The new 1 Miarmacoptjeia is useful as an intellectual exercise, and 

 many patients will probably receive a certain amount of satisfaction 

 from having prescribed for them a series of drugs with the names of 

 which they are not acquainted."

Rapid and simple process for milk analysis. Guillett (Bull des 

 Sciences riianiiocoL, 1900, 201) has devised the following process 

 for milk analysis in which no other apparatus is necessary than filter 

 paper, a funnel, an analytical balance sensitive to .0001 mg. and 

 cruci1)le. Either a Swedish ashless filter of 9 cm. diameter or 

 ordinary of known ash weight is selected. 



1. Specific Gravity: — An accurately measured volume of 2 cc. 

 of the well-mixed sample is carefully measured (at 15° C.), spread- 

 ing over the inner of two filters placed one inside of the other, four 

 folds to each side. This is quickly weighed and then divided by 

 1.99832 which represents the specific gravity. 



2. Total Solids:— Six drops of dil acetic acid are then spread 

 around the edges of the filter which is dried at 95° C. After de- 

 ducting the tare of the filter and funnel, the difference in weight 

 represents the Total Solids. 



3. Butter Fat:— The butter fat is estimated by extracting the 

 filter with petroleum ether (40 to 60° C.) or ether, which is poured 

 over the upper edges until when a drop taken from the tip of the fun- 

 nel fails on evaporation to leave any appreciable fatty residue. The 

 filters are dried and weighed, the loss in weight represents fat. 



4. Lactose and Soluble Salts :— Wash the previously dried filter 

 with hot water into a 50 cc. cylinder until the washings measure 23 cc. 

 Filter is dried and weighed. The loss in weight represents Lactose 

 and Soluble Salts.
