Observations on the coronary arteries of 100 embalmed and 20 fresh hearts of Chinese children were made. The results were as follows: 1. The point of origin of the coronary arteries was found horizontally at the middle third of the aortic sinus in 90.5%, and vertically below the upper margin of the aortic sinus in 91.5%. The diameter of the opening of the left coronary artery was greater than that of the right side in 77%' lesser than that of the right side in 4%, and equivalent to that of the right side in 19%. 2. The accessory coronary arteries occurred in 47% of the cases, and all were found on the right side. In one case, an accessory coronary artery distributed to the anterior wail of the right atrium. 3. Type II, i.e. the posterior wall of the left ventricle which was mainly supplied by the right circumflex branch, was the most common type of distribution. It occurred in 59%. 4. The interventricular septum was supplied by both the anterior and posterior descending branches, the proportion of which is determined by the length of the two descending branches. 5. The left coronary artery divided into 3 main branches (anterior descending, diagonal, left circumflex) in 56%. 6. Ramus septi fibrosi which originated from the right circumflex was found in 97% and from the left circumflex in 3%. 7. Ramus ostii cavae superioris was a constant branch, originating from the right side in 64% and from the left side in 36%. 8. The difference in number of the blood vessels to the left and right ventricles was not obvious.

In cat under the influence of a suitable combination of anesthetic and convulsant, e.g. chloralose and semicarbazide, both click and flash elicited electrical response in extensive regions of the cerebral cortex. Making use of the response in the sensorimotor cortex as the indicator, the nervous pathways mediating the productions of such response were analysed. The initial complex positive phase of the electric response in the sensorimotor cortex elicited by a click showed three distinct wavelets having latencies of 8-9, 18-20 and 30-35 msecs respectively, the 2nd and 3rd wavelets being much larger than the 1st. The response persisted essentially unchanged after complete bilateral destruction of the auditory cortex, but disappeared completely after bilateral destruction of the medial geniculate bodies(MG). Conversely direct stimulation of MG elicited a response in the sensorimotor cortex practically the same as that called forth by a click. When the regions around the thalamic nuclei ventralis medialis(VM) and ventralis anterior(VA) were destroyed, the 2nd and 3rd wavelets of the response disappeared together. The 1st wavelet appeared to be a subcortical event electrically spread to the cortex, as it could be still picked up from the white matter after the removal of the cortex. Under the same experimental conditions the response set up in the sensorimotor cortex by a flash of light in comparison with that elicited by a click, appeared to have a longer latency of 29-33 msec. Three suscessive positive wavelets could also be distinguished in this response, although the separation of these wavelets was not always as distinct as in the case of auditory stimu- lation. The second and the third wavelets had a latency of about 38-42 msec. and 48-52 msec. respectively. Complete bilateral removal of the visual cortices decreased the size of the response and increased its latency. However, even in the complete absence of the visual cortices, stimulation of the lateral geniculate body(LG) could elicit essentially the same electrical response in the sensorimotor cortex as usually called forth by a flash of light, apart from the difference in latency. Analogously as in the case of auditory stimulation, bilateral destruction of LG caused a complete disappearance of the response to the flash. An amount of destruction in the region of VA and VM such as sufficient to abolish completely the 2nd and 3rd wavelets of the response due to a click, usually also greatly diminished the 2nd and 3rd wavelets of the response to a flash, leaving the 1st wavelet practically unaffected. This 1st wavelet in the response to a flash, like the 1st wavelet in the response to a click, was also due to thalamic activity electrically spread to cortex. Our general conclusion regarding the irradiation of auditory and visual impulses to the sensorimotor cortex as indicated by the kind of responses being studied is that the pathways involved are basically subcortical, the chief routes being from the geniculate bodies via the thalamic diffuse projection system. However, the effective working of the subcortical pathways may require varying degrees of facilitation from the cortex. Results such as that the removal of the visual cortex decreased the size and lengthened the latency of the response of the sensorimotor cortex to the photic stimulus, may be interpreted on this basis.

The majority of seamen in China can predict the time of tide at the ports of their navigational activities by means of the method of using the daily log of 0.8 hour from new moon or full moon instead of the moon's transit which is added to the luni-tidal intervals.The equations used in the method are as follows:1.Time of high water=(No.of lunar date-1)×0.8 hour+high water interval.2.Time of low water=(No.of lunar date-1)×0.8 hour+low water interval.3.Time of high weter=time of low water±06124.Time of low water=time...

The majority of seamen in China can predict the time of tide at the ports of their navigational activities by means of the method of using the daily log of 0.8 hour from new moon or full moon instead of the moon's transit which is added to the luni-tidal intervals.The equations used in the method are as follows:1.Time of high water=(No.of lunar date-1)×0.8 hour+high water interval.2.Time of low water=(No.of lunar date-1)×0.8 hour+low water interval.3.Time of high weter=time of low water±06124.Time of low water=time of high water±06125.Time of next high water = time of high water±1224 6.Time of next low water=time of low water±1224The method can be used to predict the tidal time of any day at a port where the luni-tidal interval and the lunar date are known.It can also be employed for a port to make a short half-monthly tidal table used alternatively in every half-month according to the lunar calendar.In the present paper,a full account of the method is given in two parts,the first part dealing with the method of predicting the time of tide of any day,and the second part describing in detail the procedure of making the half-monthly tidal table.It is hoped that the present paper may be useful to sea-fisheries and navigation.
