Dear Listservers

I have had a successful response to my message about the TVB procedure in the 7th edition of Pearson's book and have been sent a copy of the relevant pages. If you are interested the method described there is that of Lücke and Geidel, 1935, that is direct distillation of fish muscle with magnesium oxide. It was dropped from the 8th edition which does not describe measurement of TVB by any procedure.

Thanks.

Dear Listservers

I am reviewing methods of measuring TVB in fish, especially early methods. Some publications refer to a method in 'Chemical Analysis of Foods' by D. Pearson, 7th edn. published in 1977. I have the 8th edn., now titled 'Pearson's Chemical Analysis of Foods', but it does not contain a procedure for measurement of TVB. Does anyone on the Listserve have access to the 7th edn and can confirm that it does have a description of a procedure for TVB determination, and possibly send me a copy or transcript of the procedure.

Thanks.
