In Giessen Liebig was surrounded by industrious colleagues, who appreciated the value of his researches, and were ready in any manner to act under his direction for the advancement of the sciences they had at heart. It was in 1848 that Liebig proposed to his colleagues to draw up au annual report on the progress of chemistry. Professor Kopp was associated with Liebig in editing the work, whilst Professors Buff, Dieffenbach, Ettling, Knapp, Will, and Lammur were named as contributors. This work has appeared annually, and is a rich depository of chemical information. It was hoptd that an English translation would be sufficiently appreciated to have a remunerative sale, and the first four volumes were translated into English by Dr. Hofmann, M. Warren De la Rue, and Dr. Bence Jones, but it does not appear to have been continued for more than four years. One of the last works of Professor Liebig to which we think it necessary to allude, is his 'Familiar Letters on Chemistry.' This volume consists of letters on various subjects connected with chemistry, which are intended to show the importance of the study of chemistry as a general branch of education. Some of them were first published in Germany, end others appeared at intervals as a first and second series translated into English and edited by Dr. Gardner. They have gone through several editions, the last of which in one volume with con siderable additions was published in 1851. This is gracefully dedi cated to Sir James Clark, Bart., who has taken so much interest in the foundation and devclopmeut of the Royal College of Chemistry. This work is charmingly written, and indicates one of the sources of Liebig's influence on the public mind. Few men write more clearly or exhibit a more genuine enthusiasm in the importance and value of hie science than Professor Liebig. These letters have carried
chemistry and its results into localities where it would be impossible it should be found if treated in a dry and technical manner. The subjects on which he writes are those with which all are most familiar, and he clearly demonstrates that there is no one so humble in life, none so exalted in station, none so occupied, that a knowledge of the principles of chemistry may not be of the greatest possible advantage.
Such a man as Liebig was likely to receive honour. The Grand Dnke of Hesse made him en hereditary Baron in 1845. Ho was made a fellow of the Royal Society of London in 1840. He has been invited to fill chairs of chemistry in England, and also on the continent of Europe, especially that of Heidelberg. All these be refused. In 1852 however he was induced to accept the Professorship of Chemistry at Munich, with the position of President of the Chemical Labora tory. He has been elected foreign fellow of most of the scientific societies of Europe and America that recognise chemistry. In 1854 a subscription was raised in Europe for tho purpose of presenting him with some mark of the high esteem in which his labours were held. This subscription realised a sum above 1000/. A part of it was spent in purchasing five handsome pieces of plate. This number was selected in order that one piece may be handed down to each of the five children of the baron, should they survive their father. The remaining portion of the money, 4601., was presented him in the form of a cheque.
The Baron von Liebig has formed the moat intimate associations in England, and often visits this country. He was present at the meeting of the British Association held in York in 1b43, and again at the meeting held at Glasgow in 1855.
