The dog: normal values for red cell counts, haemoglobin, blood sugar and blood urea nitrogen and a practical statistical method for evaluating such data’, Onderstepoort Journal of Veterinary Research, vol. 33, no. 2, pp. 353-361.0330-2465http://hdl.handle.net/2263/57891The journals have been scanned in colour with a HP 5590 scanner; 600 dpi. Adobe Acrobat v.11 was used to OCR the text and also for the merging and conversion to the final presentation PDF-format.The normal ranges for red cell counts, haemoglobin, blood sugar and blood urea nitrogen have been calculated for apparently healthy dogs emanating from the immediate surroundings of Onderstepoort. The statistical method involved makes use of cumulative relative frequency curves. A note is appended on the construction of these curves and the application of the "distribution-free tolerance limits test" to the results obtained.en© 1966 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
