The smaller water bath (Fig. 2) was 

 made for the use of individual (research) 

 students. It is cylindrical in form, 

 twenty-five centimeters high and of 

 about the same diameter. On one side 

 there is a semicircular projection form- 

 ing a chamber for the thermostat. This 

 is separated from the main tank by 



experienced considerable annoyance 

 from the accumulation of paraffin sec- 

 tions which could not be mounted at the 

 time they were cut. In conference with 



means of several narrow strips of copper 

 soldered at each side. The tank is 

 provided, like the larger one, with a 

 perforated false bottom. The cover has 

 an opening for a thermometer. An 

 apparatus of this size makes an admira- 

 ble milk pasteurizer. It is not expensive 

 and when properly set up requires 

 comparatively little time to operate it. 



The Friedberg burner has been found 

 to be very satisfactory for these baths, 

 as they possess to an unusual degree, 

 when properly adjusted, the desirable 

 quality of maintaining a very small 

 flame without striking back. The Roux 

 thermostat seems to be the best regu- 

 lator for this particular purpose. It 

 is constructed out of metal and conse- 

 quently it is not easily broken. It is 

 readily adjusted and quite as sensitive 

 as the ordinary spirit or mercury 

 thermo-regulators. veranus A. Moore.

A Cabinet for Paraffin Sections. 



In my classes in embryology, where 

 each student is required to section 

 and study several embryos, I have

our college carpenter, a cabinet for the 

 temporary storing of these sections was 

 devised which has been found to be very 

 convenient, both in embryology and his- 

 tology. It fills three conditions, com- 

 pactness, freedom from dust, and 

 renders it impossible to pile up sheets 

 of sections. 



I give herewith a description, hoping 

 that it may be suggestive, if not directly 

 available in its present form, to those 

 who have had similar difficulties. 



It is a box 27J inches by 121 inches by 

 8i inches wide, outside measure- 

 ments, and is made of one-half inch 

 basswood and picture backing. The end 

 is closed with a closely fitting door 

 opening downward. There are twelve 

 trays constructed as shown in detail 

 drawings. 



The sides are made of one-half inch 

 stuff grooved one-fourth inch deep to 

 receive edges of trays. The space be-
