gelatin gel in each instance. After standing for 12 hours duplicate 

 rectangles 5 x 2.5 cm. in surface area were cut and placed on watch 

 glasses to dry in a current of warm air (3o°-40° C.) to a moisture 

 content which did not exceed 3.5 per cent. The rate of moisture 

 loss was followed by frequent weighings of the gelatin plates 

 during the drying process, but no marked differences in rate of 

 moisture loss were observed. The dried sections were then placed
