 Gat, G. — [Home-made Microtome.] 



[" The materials needed are a block of hard wood 5 in. by 3| in. by 2 in., a fine 

 thumbscrew with a nut on it, a piece of glass tubing, and a glass slide cut length- 

 wise through the middle. Plane the top of the block perfectly true, then bore a 

 hole, the centre of which should be IJ in. from the end, which the glass tube 

 will exactly fit. Saw a strip from the bottom of the block, and fit the nut in the 

 hole. Cement the glass tube in the hole in the large block with marine elue, 

 allowing it to project through nearly the thickness of the glass side. Cement 

 the glass slips on the top touching each side of tiie tube. Fit a block of wood 

 1| in. long, with a rivet in the bottom, so that the thumbscrew will work smoothly 

 on it, to the glass tube. Screw the 3/8 in. strip with the notch in it to the block, 

 and cut a notch l\ in. by 2J in. in the block to fasten it to a table, and the 

 microtome is complete. Sections may be cut with a flat or common razor."]

Perenyi's Mikrolektron, for hardening, staining, and imbedding.*— 

 Prof. J. V. Perenyi has devised an apparatus, which he calls a "Mikro- 

 lektron," for facilitating the processes of hardening, staining, and imbed- 

 ding without incurring the risk of damaging the preparation. Figs. 250-252

give a complete idea of the apparatus, which is nothing more than a 

 rectangular vessel made of glazed majolica, and placed for convenience on a 

 metal stand A (fig. 250). A dish of the size recommended, measures 16 cm.
