Garbini's Closed Water-bath.* — Dr. A. Garbini uses a moclification 

 of the wfttcr-bath described in his ' Manualc per la tecnica del micro- 

 Bcopio,' for the purpose of heating slides on which sections are to be 

 stuck by Giesbrecht's or Mayer's methods. 



The apparatus (fig. 184) consists of a rectangiilar box 20 cm. long, 

 15 cm. broad, and 4 cm. high, closed hermetically. From the middle of 

 the bottom projects the copper bulb a, having a diameter of 8 cm. On 

 one side is a small tube b, with a stop-cock. It connects with a wider tube 

 c, into which may be fitted a cork bung, and a glass funnel, for the purpose 

 of filling the box. Upon the top of the box, by means of four fluted pillars

(the two front ones • 5 cm. high, the two hind ones 4 cm. high) and 

 three plates of glass fitting into the flutings a compartment is formed. 

 This is closed above by a glass lid moving on hinges fixed to the posterior 

 columns. From the figure it will be evident that this compartment is not 

 quite closed Avhen the lid is down, as there is a narrow aperture in front, 

 and a wider one behind. 



Behind the box are two glass tubes 3 cm. high, and with a diameter of 

 1 • 5 cm. Into one of these cl fits a thermometer, and into the other a 

 bent glass tube e, to carry off the steam. 



Loss of water may be prevented by using, instead of the tube c, a
