I will now direct the attention of scientists to a previously unnoticed cause which brings about the metamorphosis and decomposition phenomena which are usually called decay, putrefaction, rotting, fermentation and moldering. This cause is the ability possessed by a body… — Justus von Liebig Copy Share
By the deficiency or absence of one necessary constituent, all the others being present, the soil is rendered barren for all those crops to… — Justus von Liebig Copy Share Image
I will now direct the attention of scientists to a previously unnoticed cause which brings about the metamorphosis and decomposition phenomena which are usually called decay, putrefaction, rotting, fermentation and moldering. This cause is the ability possessed by a body engaged in decomposition or combination, i.e. in chemical action, to give rise in a body in contact with it the… — Justus von Liebig Copy Share
The loveliest theories are being overthrown by these damned experiments; it's no fun being a chemist anymore. — Justus von Liebig Copy Share Image
The secret of all those who make discoveries is that they regard nothing as impossible. — Justus von Liebig Copy Share Image
If it is impossible to judge merit and guilt in the field of natural science, then it is not possible in any field, and… — Justus von Liebig Copy Share Image

And yet the latter are the proper source from which the others flow. Practice alone can never lead to the discovery of a truth or… — Justus von Liebig Copy Share
There is in the chemist a form of thought by which all ideas become visible in the mind as strains of an imagined piece of music. This form of thought is developed in Faraday in the highest degree, whence it arises that to one who is not acquainted with this method of thinking, his scientific works seem barren and dry,… — Justus von Liebig Copy Share
Chemistry, in its application to animals and vegetables. Endeavours jointly with physiology to enlighten us respecting the mysterious processes and sources of organic life. — Justus von Liebig Copy Share Image
The more fodder, the more flesh; the more flesh, the more manure; the more manure, the more grain. — Justus von Liebig Copy Share Image
But it must not be forgotten that ... glass and porcelain were manufactured, stuffs dyed and metals separated from their ores by mere empirical… — Justus von Liebig Copy Share Image
A time will come, when fields will be manured with a solution of glass (silicate of potash), with the ashes of burnt straw, and… — Justus von Liebig Copy Share Image
