The application of the paraflin-imbedding method in botany. 
DR. J. W. MOLL. ' 
In the following lines it is my purpose to introduce into 
botanical science the paraflin-imbedding method which zool- 
ogists generally have employed for several years, and with 
great success. It will be understood that the method here 
studied with ease. That, notwithstanding these advantages, 
the imbedding method has not been made use of to any 
extent! in botany must be probably ascribed to various 
causes. One cause of the failure of experiments in this direc- 
tion may have been owing to the fact that the imbedding 
method was not combined with other methods ; and still, as 
has already been remarked, this is necessary in order to-in- 
sure ‘success. In the second place no vegetable parts pre- 
served in alcohol should be used for imbedding, as it will be 
often found very difficult to permeate them with paraffin. On 
the contrary, it is necessary to employ chromic or picric acid,
