The field of knowledge was adapted to new developments by mcludmg the keywords Ferroelectncs (12pp), Fatty Ammes (6 pp ), Fatty Ammo Oxides (2 pp ), Flocculation Agents (6 pp ), hqmd Crystals (16 pp ) and Formazan Dyes (8 pp ) The section about Lighters was superseded by an title about Refractory Materials (18pp ) Several keywords were assigned to other chapters, such as Explos~ous and Dyemg, Esters are now treated m an isolated section (10 pp ) For a great number of keywords the previous extent was mamtamed. for mstance Vmegar (16pp ), Fats, Chls and Fatty Acids (94 pp ). Fluorme (70 pp ) and Formaldehyde (16 pp ) should be mentioned Fmally, the treatment of Felt (4pp ) IS an example for the comprehenswe appbcabtity of thus reference work, which mves valuable mformahons to the chemist m the laboratory, to the engmeer m an mdustnal plant as well as to the user of a special subject hke clothmg mdustry

notes Sentences whuzh may have sounded reasonably satlsfactory, mven the benefit of all the mflexlons possible in speech, look dull and clumsy on the prmted page Poor punctuation of such sentences IS a frequent cause of n-ntatlon On p 88 there IS the stnkmg phrase “For the remamder of tbs course” (my ~tahcs) which seems odd m a book but approptrate enough m a lecture, and on several occasions a colloqmal use of the second person plural turns up m the text for no particular reason There IS very little mathematics m the book which 1s not m Itself a fault though symbols are not always properly explamed and some defimtions, such as mtrms~c vlscoslty on p 78, are actually wrong An expelrenced sclentic pubhsher should have detected the absur&ty of sphttmg the short equation f -fL = aAT between the bottom of p 79 and the top of the next page overleaf The fist thud of the book concerns the nature of Iugh polymers, the mteraction of polymer molecules, and the amorphous and crystalhne states Tlus 1s by far the best w&ten and most satisfactory part Later on the book becomes mcreasmgly scrappy and unrehable Overall I cannot see that It IS hkely to serve any useful purpose D A BLACKADDER
