The analysis of the data shows that the growth of roe deer from the eastern part of Greater Poland (Wielkopolska) is very similar to that of specimens from other areas in Poland. A comparison with excavated bone material revealed only slight and fluctuating differences. The roe deer from the areas to the west of Poland are larger and those from the areas to the east of the country are the largest.
The objective of the study was to analyze the wing musculature of the African ostrich. The investigation was conducted on four three-day old chicks of the ostrich. The muscles were characterized by poor development due to a very young age, and no flight abilities. The basic muscle units were described, the measurements of their length and width were taken and their mutual relation was calculated. All values were collected in a table. The photographic documentation was also prepared.
