Estimations of sodium, potassium, calcium, magnesium, chloride and sulphate have been made on the blood and muscle of marine molluscs and of the freshwater clam,Anodonta.On comparing marine blood with sea water it appears that the cephalopods show a regulatory power (i.e. difference between blood and sea water) with respect to all ions tested except sulphate. The gastropods have a regulatory power for calcium, magnesium and chloride; the pelecypods for calcium and magnesium.Calcium is always higher in blood than in sea water, while magnesium is lower. Chloride, where it differs, is lower.If muscle is considered as two phases, cells and intercellular blood space, then from whole muscle and blood analyses it is possible to calculate the spaces between the cells, which work out at 11 % for pelecypods and 18 % for the other two groups. Further calculation gives the constitution of the cells themselves, leading to the conclusion that, of the ions under consideration, only K is present in the Pelecypoda and Cephalopoda, while the Gastropoda may have some Ca and Mg as well as K.As expected the fresh-water clam contains little inorganic material. In relative proportions its blood is characterized by more calcium and less magnesium and chloride than that of marine forms. In muscle cells potassium dominates but other ions are present as well.This work was carried out at the Laboratory of the Marine Biological Association, Plymouth, in the summers of 1936 and 1937, and at the Oceanographic Institution, Woods Hole, in 1939. It is a pleasure to express our thanks to the Directors and Staffs of these establishments for accommodation,facilities and advice during the progress of the investigation.

软体动物血液和肌肉的无机结构

已经对海洋软体动物和淡水蛤的血液和肌肉进行了钠、钾、钙、镁、氯化物和硫酸盐的估计,无齿目. 在比较海洋血液和海水时,似乎头足类动物对除硫酸盐以外的所有测试离子都表现出调节能力(即血液和海水之间的差异)。腹足动物对钙、镁和氯化物具有调节能力;钙和镁的钙和镁。血液中的钙总是比海水中的高,而镁则较低。不同之处的氯化物较低。如果将肌肉视为两个阶段,即细胞和细胞间的血液空间,那么从整个肌肉和血液分析中可以计算出细胞之间的空间,对于 pelecypods 和其他两组为 18%。进一步的计算给出了细胞本身的构成,得出的结论是,在所考虑的离子中,只有 K 存在于 Pelecypoda 和 Cephalopoda 中,而腹足纲动物可能含有一些钙和镁以及钾。正如预期的那样,淡水蛤几乎不含无机物质。在相对比例上,其血液的特征是比海洋形式的血液含有更多的钙,更少的镁和氯化物。在肌肉细胞中,钾占主导地位,但也存在其他离子。这项工作于 1936 年和 1937 年夏天在普利茅斯海洋生物协会实验室和 1939 年在伍兹霍尔海洋研究所进行。很高兴感谢这些机构的董事和工作人员在调查过程中提供的住宿、设施和建议。在相对比例上,其血液的特征是比海洋形式的血液含有更多的钙,更少的镁和氯化物。在肌肉细胞中,钾占主导地位,但也存在其他离子。这项工作于 1936 年和 1937 年夏天在普利茅斯海洋生物协会实验室和 1939 年在伍兹霍尔海洋研究所进行。很高兴感谢这些机构的董事和工作人员在调查过程中提供的住宿、设施和建议。在相对比例上,其血液的特征是比海洋形式的血液含有更多的钙,更少的镁和氯化物。在肌肉细胞中,钾占主导地位,但也存在其他离子。这项工作于 1936 年和 1937 年夏天在普利茅斯海洋生物协会实验室和 1939 年在伍兹霍尔海洋研究所进行。很高兴感谢这些机构的董事和工作人员在调查过程中提供的住宿、设施和建议。
