    amounting to 50 over Rajputana and the neighbouring parts of the United Prov¬ inces and over the Bombay Deccan and Khandesh. On the 5th rain commenced over the southern half of the Peninsula and fairly heavy daily rain continued over that region from the 5th to the 21st, when, owing to the formation of a depres¬ sion over the Bay, and the consequent diversion of the moist current from the south of the Peninsula to the depression area, the fall somewhat abruptly ceased. In consequence of the above rainfall the mean temperature of the Peninsula was generally lower than usual. During this period temperature over northern India was unsteady and varied by small amounts from the normal. On the nth, 12th, and 13th there was some snow and rain over Kashmir and light rain over the Punjab. In consequence a decided fall of temperature took place in the north-west and in some divisions the mean daily temperature was reduced to below the normal. On the 14th and 15th it became rapidly hotter in Sind and these high temperatures spread eastward over Gujarat, Rajputana and Central India. On the 21st a large shallow low pressure area lay over the Bay of Bengal and rain was falling over Burma, deltaic Bengal, Orissa and the Circars : the low pressure area gradually concentrated and on the 23rd a depression was shown off the coast near Vizagapatam. This depression advanced north-north-eastward and north-eastward up the coast, entered Bengal on the 25th and then passed eastward through Upper Burma and Cachar during the 26th. The storm occasioned a considerable fall of rain in the north-east and the temperature over Burma, Assam and Bengal was somewhat lower than usual. During this period the mean temperature was very excessive in the north¬ west. From the 27th to the end of the month the weather was practically rainless throughout the country and the mean temperature was generally above the normal—more especially in the north-west where the average excess ranged between 2° and io.° Quiet weather prevailed over the Indian land area during November. From the 1st to the 9th the only rainfall reported was same scattered showers, mainly over Burma, Assam and the extreme south of the Peninsula. During this period the most marked feature of the weather was the excessive heat prevailing over north-west India, where the mean temperature varied between 40 and io° above the normal. Temperature was also higher than usual—though to a less extent than in the north-west—over north-east India, the showers in that area having been less frequent and less heavy than usual. On the 10th moderate to heavy rain set in over the southern half of Madras. The rainfall diminished both in amount and extent between the 12th and the 16th, extended again on the 17th and 18th, was light between the 19th and 23rd, but became heavier and more general on the 24th and subsequently extended along the west coast reaching as far north as Bombay, Poona and Ahmednagar on the 27th and 28th. During the period from the 1 ith to the 15th the temperature was unsteady over northern India but was very high over north-west and central India. On the 16th a fall took place, but, though the mean temperature in the north-west was lowered, the fall was not sufficiently large to bring it below the normal in that area. In the north, east and centre, on the contrary, the mean temperature fell to below the normal and remained normal or below till the 24th. On the 25th a decided increase of temperature occurred over the Peninsula, and though the rainfall over the south of the Peninsula, the west coast and the Bombay Deccan temporarily made the air cooler than usual in those regions, the interior of the Peninsula remained warmer
