The Microscope. 



To give the intestines cilimentaiy problems to solve, which shotild 

 be solved by cooking, is 

 putting man between two 

 mill-stones, on of which 

 may represent the inevitable 

 battles of life without the 

 body, and the other the 

 needless intestinal wars with- 

 in, the latter uselessly handi- 

 capping from the outset.

As to the sweet potato. — 

 It is interesting to note the 

 difference between the raw 

 and cooked, as shown by 

 figures 5 and 6. There is the 

 same reticulation in the raw 

 and the same formation in 

 the cooked as found in the 

 white potato, whose stems 

 are clustered stalks, while 

 the sweet potato is a climb -

HOW TO MOUNT A TAPE-WORM. 



W. S. JACKMAN. 



A JOINT or segment of tape- worm, mounted in the following 

 -*• ^ manner, will show the ovaries and eggs very clearly. Procure 

 good-sized specimens with well-filled ovaries. Remove from the alcohol 

 in which they have hardened, wash, and immerse in glycerin for a 

 few days, until clear and pulpy in appearance. Place between two 

 strips of glass and squeeze until the specimen is quite thin. Clamp 

 with a stiff spring clothes-pin and allow it to remain thus for several 

 hours — a day is not too long. Sufficient glycerin will adhere to the 

 glass to keep it moist; next place in the stain; a few minutes will 

 usually be long enough. Pass it then through the fixing solution.
