A right hallow circular cylinder of quartz having its generator parallel to the principal axis liberates electricity when subjected to torsion about its axis. Charges of opposite signs appear on the inner and outer surfaces. When torsion is applied in the same sense as that of the optical rotation, positive electricity is developed on the outer surface, and vice versa. The quantity of electricity produced by the action of a couple of moment C on a hollow quartz cylinder of external diameter d0, internal...

A right hallow circular cylinder of quartz having its generator parallel to the principal axis liberates electricity when subjected to torsion about its axis. Charges of opposite signs appear on the inner and outer surfaces. When torsion is applied in the same sense as that of the optical rotation, positive electricity is developed on the outer surface, and vice versa. The quantity of electricity produced by the action of a couple of moment C on a hollow quartz cylinder of external diameter d0, internal diameter di and length l is klC/do do-di), where k is equal to 9.2x10-8 in absolute C.

割水晶成一圆柱,圆柱之轴即为晶体之光轴,在圆柱之中心穿一孔道,使成一空心圆柱壳,以金属箔敷於圆柱壳内外侧面成两电极。当圆柱之一端固定,一端被扭,则两电极发生异号而等量之电荷,扭转之方向既易,内外两极电荷之号亦互易。若扭力偶矩左旋,则左旋水晶柱之外极得正电;若扭力偶矩右旋则右旋水晶柱之外极得正电。 吾人曾由实验测定水晶圆柱之长短l,内外直径d_i及d_0之大小,与由扭偶矩C所生电量q之关系式如次: q=k(l/(d_0(d_0-d_i)))C式中K为一常数,在C.G.S.绝对静电单位制中等於9.2×10~(-8)。

1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are developed...

1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are developed from the asexual mother either singly or in combination with other kinds and asexual daughters.6. Parthenogonidia develope very early in young embryos long before the latter become matured and escaped from the mother colony. 7. During the early development of parthenogonidia, at least from first to fifth or sixth divisions, no growth of the whole embryo takes the place while the number of cells increases.8. Spermatogonia attain fully-grown size and begin to divide before the time of the birth of the colony.9. The development of spermatogonium consists of seven successive divisions in forming a bundle or platelet of one hundred and twenty eight spermatozoa or microgametes.10. The number of ovaries in a female colony varies from twelve to fourty six. Generally, the larger the colony, the more the ovaries developed.11. Risexual colonies contain only two or three spermatogonia in addition to fourteen to twenty seven ovaries.12. In general, specimens recorded in Nanking are identical to those from the tropical regions such as Africa and the Philippine Islands.

關於菲洲團走子之分佈,按記載所及。僅限於菲洲,菲列濱,南印度等熱带區域。今在南京發現,於地理分佈上實為一新記錄。此種團走子在羣體成熟之後,其體質细胞間,並無原生質線交相聯絡。無性羣體每含有二至六大小不同成對均置之無性幼羣體。幼羣體在脫離母體以前,往往含有第二代幼體。各種有性羣體,亦自無性母羣體中發達而成。雄性羣體,皆为橢圓形,而較其他羣體為小。雌性羣體中之卵或大配子约有十二至四十六。雙性羣體只含有二或三精原细胞,及十五至二十七卵或大配子。孤性生殖细胞在幼羣體内即發生。當最初五或六次分裂時,细胞雖增加,而幼胎並不長大。精原细胞经七次連續之均等分裂,而成一束一百二十八精子或小配子。

1. The conformity of the pattern of Cicindela anchoralis to what has been considered typical of the genus becomes in- telligible if the middle band, which is undoubtedly the most variable of the markings of this species, is assumed to have shifted forward and to have developed extensions both cephaled and caudad along the lateral margin and on the disc of the eIytron.2. The variation of the pattern is of the continuous type and proceeds in one principal direction. As expected, some in- dividuals depart...

1. The conformity of the pattern of Cicindela anchoralis to what has been considered typical of the genus becomes in- telligible if the middle band, which is undoubtedly the most variable of the markings of this species, is assumed to have shifted forward and to have developed extensions both cephaled and caudad along the lateral margin and on the disc of the eIytron.2. The variation of the pattern is of the continuous type and proceeds in one principal direction. As expected, some in- dividuals depart from this main series, in one way or another and ten such sub-types have been recognized in this study. The range of variation is very considerable.3. The male sex is found to have a greater tendency to lose its pigmentation, and this fact is interpreted as indicating its having a more variable middle band.4. Mating between the different types is entirely at random, the frequency of any given combination is apparently a function of the abundance of the individuals in a given class.5. In describing the elytral pattern of this species, Chevrolat (1845) used these words: "vitta anchorali, cum lienola pone humerum (femina amplioribus); cupreis". He evidently had regarded as typical the pattern showing fullest pigmentation. The present study shows, on the other hand, that such a pat- tern, while most primitive, is not the most representative. The typical pattern is to be sought in Class Ⅳ, the model class. This last remark certainly has wider application and merits the consideration of taxonomists describing highly variable forms.

斑蝥科甲虫翅鞘色型之差異,在一部份種類中,極为顯著。本篇所論,根據中國种錨紋斑蝥,於廿二年夏採於厦門北岸,計雌雄共九百餘個,內有交配者六十二對,所得結論如下: (一)本種色型,甚为異特。若以美人薛福特氏所立之本屬理想模式色型推解,則其中間淡色横斑,較为移前,其左右則向上下分枝成H形。 (二)此種色型之變異為連續式仝趨一主要方向,但依其變異之分岐,可别为十種副式色型,詳情已於西文中加以討論。 (三)雄虫翅鞘之中間淡色横斑變異較大,其深色紋斑之傾向於縮小亦因之較雌性为甚。 (四)兩性交配,与色型之差異,全無關係。 (五)大部份個數皆呈現中間色型。其趨向於兩極端者(深色或淡色特别發達者)乃屬少数。因此分類學者於記述变異極大之種類時,應发中間色型者為代表。
