The content of hemoglobin and myoglobin in meat-beef, horse and whale-as estimated simultaneously by the spectrophotometry on the extract saturated with carbon monoxide. Hemoglobin and myoglobin were extracted from the homogenized meat with acetate buffer pH 4.5 as described by de Duve. The absorption spectra of the mixtures of carboxyhemoglobin and carboxymyoglobin were plotted by Beckman DK self-recording spectrophotometer or Hitachi EP U-1 spectrophotometer. The content of hemoglobin and myoglobin was obtained from the absorbancy at 560, 570, 576 and 580mμ by the nomograph made by Tsushima and Okazaki.The rate of hemoglobin and myoglobin was also calculated by other methods such as that of de Duve and that of Poel. The sum of these proteins was also checked by cyanide-methemoglobin method.The rate of hemoglobin and myoglobin as observed to remain constant in spite of the difference of the animal species and the localization in the body, accordingly in spite of the difference in the total content of the extractable heme-proteins. The content of hemoglobin was estimated to be approximately 10% of the total heme. No remarkable difference in the hemoglobin content was observed between whale and the other meat, although some difficulties in removing the blood might be conceivable in the former.The hemin content of dark muscles of bonito and tuna was also determined.

After the latter half of the 15th century, the deforestation of mountain became active in the northern frontier of Ming dynasty. Therefore, around the 16th century, Ming government prohibited the deforestation around Great Wall chiefly by military reasons. However, a lot of virgin forests have still extended at the northern foot of Qilian mountains in the upper reaches of Heihe river basin until about the 17th century. Tibetan and Mongolian people lived in this region from ancient times by nomadism, stock raising, hunting or farming. It was chiefly Han people who promoted the development and the use of timber resources. They came from Ganzhou in summer, cut down and carried away the forest woods in order to sell them. After the 18th century, under the rule of Qing dynasty, the full-scale deforestation of the Qilian mountains has begun in the upper reaches of Heihe river basin. Because the area of the forest reduced rapidly and the water-holding capacity of mountain forest decreased, the amount of water necessary for the irrigation agriculture came to be insufficient and the flood came to happen many times in the middle reaches. To deal with such a situation, the officials of Qing government understood the function of the mountain forest enough based on the field survey. They decided to make regulations concerning to the usage and the management of the mountain forest and severely punished the offender, but the effect was not so satisfactory.
