Our ChemSci Pick of the Week demonstrates a more efficient way to turn hydrocarbon feedstock compounds into valuable fine chemicals. This could be used for the synthesis of a variety of natural products or pharmaceutically relevant compounds, and help overcome a drug discovery bottleneck. We are sad to have learned of the death of Professor Sir Chris Dobson, Master of St John's College in Cambridge and long-standing friend and colleague to many in our community. There are many words, especially i n German, for which several abbreviations are in use.
These generally differ only i n length. A s examples 95 through show, i t can be assumed that originally the longer, and consequently less ambiguous, forms were i n use and that these were later shortened until only a single letter came to be accepted. B u t because these single-letter abbreviations could have several meanings and confusion set in, editors reluctantly agreed to revert to the earlier, longer forms. I n Italian, this form of confusion is rare.

As examples through show, the abbreviation of an adjective and that of its corresponding noun are frequently the same, except for the initial capital in the abbreviation of the noun. In examples through , the fact that one of two otherwise identical abbreviations begins with a capital letter is of considerable help in distinguishing between two or more meanings. In German abbreviations containing both upper and lower case letters with or without periods or spaces between them , it can be assumed for all practical purposes that the capital letter or letters will invariably refer to nouns, as evidenced by examples through In two-letter abbreviations representing compound words, if both letters are capitals followed by periods, the abbreviation generally represents a compound noun, each of its two letters being the initial letter of each noun examples through If the second letter is in lower case, both letters were taken from the first element of the compound word and there is no period between them examples and There are exceptions, as examples and indicate.
German compound nouns may also be abbreviated with three letters, in which case either only the initial one example or all three example are in upper case. Table III. Dictionaries Baudry, Hubert. De Vries, Louis. See pp. Kettridge, J. Wilson Co. Mansion, J. Patterson, Austin M.
