permanent toward alkalies. It also oc- 

 curs in the form of a powder, which is 

 amorphous, heavy, and faintly yellow in 

 color. It dissolves freely in water, but 

 only slowly. It must be protected from 

 light, and undue changes in temperature. 

 It is used in certain forms of syphilis, in 

 doses of I mil, gradually mcreased to 2 

 mils, administered 2 or three times week- 

 ly, by injection into the gluteal muscles. 



Oleum fcrricuui coUoidale, Carlson is 

 the name given to a solution containing 

 5 per cent, of colloidal iron oxide in 

 oleic acid, containing a small quantity of 

 iron oleate. It is furnished in the form 

 of a reddish-brown, clear oily liquid, 

 which is miscible in all propoitions with 

 cod-liver oil, and other fixed oils, form- 

 ing clear solutions, which are permanent 

 in nature. The oleic acid used in its 

 manufacture is obtained from expressed 

 oil of almond. The preparation is very 

 useful in the extemporaneous manufac- 

 ture of an iron containing cod liver oil. 

 As the preparation contains a definite 

 quantity of iron, the iron content of oils 

 is readily controlled. 



Kratalgin. This is the name given to 

 a preparation used in place of algoeratin 

 which is a mixture of cafifein, phenace- 

 tih and pyramidon together with phenyl- 

 amido-xanthin. The latter however does 

 not form one of the constitutes of krat- 

 algin. 



Anti-Diarrhoein. This is the name 

 given to tablets containing salicylate and 

 tannate of bismuth. 



Polygalysat, formerly known as sene- 



galysat, is a dialysate or dififusate of sen- 

 ega root. It is given in doses of 10 to 12 



drops, every two or three hours, in place 



of the infusion. 



Ergopan is a preparation containing 

 amino bodies and a number of the active 

 constituents of ergot. 



Anti-Influenzol is the name given to 

 tablets, each of which contains 0.5 

 gramme of acetyl-salicylic acid. 



APPLIED SCIENCE. 



It does not seem unwarrantable to 

 suspect that Mr. Stephen Leacock, who 

 contributed the following to the London 

 Outlook, has learned in suffering what he 

 teaches in boarding-house geometry. 

 Here are some of Mr. Leacock's defi- 

 nitions and axioms : 



1. All boarding-houses are the same 

 boarding-houses. 



2. Boarders in the same boarding-house 

 and on the same flat are equal to one 

 another. 



3. A single room is that which has no 

 parts and no magnitude. 



4. The landlady of a boarding-house 

 is a parallelogram; an oblong, angular 

 figure which cannot be described, but is 

 equal to anything. 



5. All the other rooms being taken, a 

 single room is said to be a double room. 



Among postulates and propositions the 

 following are worthy of consideration: 



1. A pie may be produced any number 

 of times. 



2. The landlady may be reduced to her 

 lowest terms by a series of propositions. 



3. A bee-line may be made from one 

 boarding-house to another. 



4. The clothes of a boarding-house 

 bed, although produced ever so far both 

 ways, will not meet. 



5. Any two meals at a boarding-house 

 are together less than one square meal.
