Dr. Engelmann submitted an abstract from his meteoro- 

 logical journal as follows: 



Though February had been milder than usual, March and April were 

 much colder than these months generally are; thus the spring was unus- 

 ually backward, and vegetation was retarded nearly three weeks. The 

 Peach and wild Plum trees are commonly in bloom about the end of 

 the first week of April ; this year, owing to the cold on New- Year's night, 

 we had no peach blossoms ; the first Plum trees he observed in bloom 

 April 25 ; similar late springs were those of 1843 and 1857. By far the 

 earliest season observed by him was that of 1842, when Peach trees were 

 in bloom, March 19, and Apple trees, March 28. The mean temperature 

 of March and April together he had found to be 50". 2 ; in the years of 

 latest spring it was 5° to 9° less ; in 1843, 41°. 4 ; in 1857, 42°, and in this 

 spring 45 J .3; while in the year of earliest spring, in 1842, it rose to 59°.9.
