part cut away is fastened. Warm Canada balsam is the best 

 thing to use to slick the himels to the glass. By this mean a 

 slide is obtained with a cavity in it which cavity can be filled 

 up with the liquid to be examined. This liquid will not run 

 out in consequence of the capillarity, then it will be very easy 

 to place horizontally the aquarium slide under the microscope. 



It will be naturally advantageous to. fasten at the two ends 

 of the slide and on each of the faces some little strips of 

 glass which will protect the aquarium. 



One of the greatest advantages which small similar appa- 

 ratuses present is this: Once the organisms are placed upon 

 the cover glass it is easy to fix them. Balsam can be dis- 

 solved in xylol and the cover glass be used for a preparation. 



These apparatuses are to be found in the stores and are 

 sold by Klonne and MuUer from Berlin. — Translated from the

MEDICAL MICROSCOPY. 



A Physician's Outfit, — The present day tendency of med- 

 ical practice is, very markedly, to rely on microscopical meth- 

 ods of diagnosis. Not only is a microscope essential, as an ed- 

 ucational instrument, to every student of medicine, it is also 

 hardly to be dispensed with in the course of any single day's 

 work by any intelligent and capable practitioner. Every state 

 of disease is expressed and characterized by some micro-organic 

 change. And the number of such afiections that may be dis- 

 covered by microscopical examination of the secretions is great, 

 and continually increasing. When, indeed, any conscientious 

 physician is found to be without the aid of this invaluable diag- 

 nostic means, that state of things may safely be attributed to 

 poverty and not intention. We deduce the suggestion ihat a 

 '' hire purchase " system, for the acquisition of microscopes by 

 the poorer members of the medical profession, could be worked 

 out to some advantage. 



A. cheap microscope is of little value to the physician, but, 

 on the other hand, one must not forget that the course of med- 

 ical education is, in itself, an expensive introduction to the bus- 

 iness of life. It is, therefore, not seldom that the young doctor 

 finds himself quite unable to buy a powerful and reliable mi-
