THE MICROSCOPE. 57 



am glad to see you. A young lady has fallen and sprained her

The latest device, which is reported to be getting alarmingly 

 common in some parts of the Dominion, is the preparation and sale 

 of " galvanized " butter. This interesting article of merchandize is 

 made in rolls, the outside of which are of the primest product of the 

 dairy, plastered on in thin layers over huge lumps of lard, sheep's 

 fat, etc., of the poorest (\w3i}i\\.y.— Post and Tribune. 



Prof. Chandler, of N. Y. City, in obedience to a resolution of 

 the aldermen, reported to the Board of Health the result of his 

 inquiries into the subject of oleomargarine. He says that it is 

 superior in all respects to the poorer grades of dairy butter sold here ; 

 that there is nothing objectionable either in the material or its 

 manufacture, and as there is nothing unwholesome in oleomargarine 

 he sees no need of legislation in regard to it to protect the public 

 health. — ^.v. 



Cheap Microscopes. — Speaking of the importance of the 

 microscope to physicians, the neglect of medical schools, and to 

 provide proper instruction in its use, the Philadelphia Medical and 

 Surgical Reporter says, that " The needed facilities are not neces- 

 sarily expensive. Simple instruments, costing not more than ^50 

 or ^60, do all the work at Strasburg, Wurtzburg, and other German 

 schools." We are glad that microscopes are getting cheap, and trust 

 the day is not far distant when every apothecary, as well as every 

 physician, will have one of these instruments. — Druggist. 



Young microscopists in preparing their beautiful diatoms for the 

 slide find it very difficult, if not impossible, to rid them wholly of 

 dirt and flocculent matter. The usual process of v;ashing them with 

 nitric acid and bichromate of potassa leaves them still quite obscure. 

 The Hon. H. L. Smith, of the Royal Microscopical Society, cleans 

 them perfectly by putting them back into the test tube after com- 

 pleting this process, with clear, soft water and a bit of common 

 yellow soap, of about the size of a pea, boiling them, and washing 

 two or three times afterward with clean rain-water. — Ex.
