The Warmest Month. — M. E. Renou re- 

 marks, in the "Annuaire" of the French 

 Meteorological Society, that throughout the 

 northern temperate zone the maximum of 

 temperature occurs, as a rule, in July. In 

 the corresponding zone on the other side of 

 the equator the maximmn comes in Janua- 

 ry. Between these two zones, or at the equa- 

 tor, the epoch of maximum falls at various 

 dates, according to the storms that rule in 

 the region. They are not so important there 

 as in the other regions, for the difference 

 between the coolest and the warmest month 

 is little at the most. A curious law seems. 

 to prevail in the distribution of the maxi- 

 mum. In North America the warmest 

 month is almost universally July ; but in the 

 southern regions of that continent it occurs 

 in August. In the Antilles it may be 'looked 

 for in September, and at Cayenne in Octo- 

 ber. Passing through South America, be- 

 fore reaching the latitude where it comes in 

 January, we find countries where it occurs, 

 in November and then in December. The 

 maximum is found in January through all 

 the southern part of that continent and in 

 Chili. In Peru it occurs in March ; there is, 

 therefore, a region between Peru and Chili 

 where it must be looked for in February. 

 North of Lima it is found in April, and far- 

 ther north in May. Finally, it comes in 

 June as we approach Sonora, and in July in 

 California, where we are brought back in 

 the returning circle to our starting-point. 

 Between Cayenne and Peru we shall evi- 

 dently find places in which the maximum 

 moves from October into November, etc., 

 and at last into March. Li the Gulf of 

 Mexico we mg^ also remark a rapid varia- 

 tion in the time of the maximum tempera- 

 ture as we go from east to west. A similar 

 distribution, marked by the same peculiari- 

 ties, is noticeable in the Old World. The
