    PREFACE OF THE AUTHOR. With the exception of a work* published ten years ago, literature has as yet been wholly unrepresented by a manual of phyto-chemic analysis. For this reason alone the above work met with a very favourable reception, which moreover was doubtless enhanced by the name of the author, who had for a long time been engaged in researches ofthat particular direction. My expectations on receiving it were great. But although I found a considerable treasure of ex- periences deposited therein, I had soon to arrive at the conclusion, that the course recommended by the author renders the performance of a phyto-chemical analysis an extremely tiresome and slow pro- cess, and one requiring a large share of patience; consequently, instead of animating to attempt analyses of such kind, it rather deters therefrom. Besides, the course of the analysis indicated therein did not meet with my approval. I decided therefore, not being inexperienced myself in these kinds of operations, to publish the method, which I have followed for many years, and which after numerous repetitions and correc- tions has been proved most practical, since it is considerably shorter than any other, and, I venture to say, is not less accurate. By this I will not assume, that my work is not capable of im- provement; indeed, I myself am striving for that incessantly still, and shall gladly acknowledge any aid from anyone, who may pur- sue the same objects. * AaleUutKj zur Analyse von Pflanzen und Pflanzen/heilen, von Friedr.
