 draped off (fig. 3). A special apparatus for neuro-surgical operations and one with 

 possibility of tilting the patient and adjusting the height of the apparatus has been 

 constructed. The patient can thus be brought to the wanted rectal temperature, kept 

 there automatically and warmed in the same apparatus in an easy, simple, and 

 neat manner.
